The first part of this chapter covers CAE (Caprine
Arthritis Encephalitis). The complexity of the disease renders a
section on its own necessary. It is only through understanding the
implications and testing for this disease that it will be brought
under control in our goat populations.
CAE
— Caprine Arthritis Encephalitis
This
is a disease which is immuno-suppressive and is caused by a retrovirus
(sometimes called lentivirus) and, in this particular instance,
affects goats. Initially the disease was known as "Big Knees" which
was one of the obvious signs when arthritis was present — actually
many other parts of the body are affected when the knees are swollen,
but that was discovered later. However, we soon learned that arthritis
was only one part of it; encephalitis, hard udder, irreparable lung
damage (with persistent pneumonia), outbreaks of CLA (Caseus Lymphadenitis)
that would not clear up, one-sided udders, brain lesions, spinal
damage, chronic mastitis and a host of generally unexplainable wasting
conditions were all due, directly or indirectly, to CAE. The goat
is left without immune defenses against even the most ordinary ailments.
AIDS
in humans, Maedi Visna in sheep, Bovine Visna in cattle, Equine
Infectious Anemia in horses and so on, every species has its own
variety of immune system disease. We can only speculate on the reasons
for the sudden upsurge in immune system afflictions. Some schools
of thought blame our over enthusiastic use of vaccines, drugs, sprays
and artificial fertilizers — our general health has declined seriously
and immune systems do not seem to be what they were. All the different
autoimmune diseases are remarkably similar, all that differs is
the mode of transmission — the net results seem to be the same —
a slow, lingering death once the disease becomes active.
There
are many different opinions about the frequency and mode of spread
in goats (as in other species), lateral or vertical in other words.
However, there is absolutely no doubt that the chief mode of infection
in goats is via the milk and colostrum. Of course, the blood, as
in all kinds of autoimmune diseases, is the greatest carrier; however
in properly carried out animal husbandry, infection by blood (via
injection needles or tattooing) should not occur.
CAE
and Copper
There
is a strong link between CAE and lack of copper in the diet. Before
anyone knew what it was, the disease had been documented in the
United States as a condition where the goat either had not received,
or had been unable to assimilate, the correct amount of copper.
It seems that a diet deficient in that mineral would predispose
an animal to lateral infection.
My
goats have always had supplementary copper since before the start
of the CAE era (or what we considered to be the start). This was
due to Dr. Alan Clark, B.V.Sc. who tested copper levels in my herd
so we could establish the dietary amounts needed. Seeing the copper
levels are correct would be a small price to pay in the control
of this illness. In 1990, in the United States, St. Johnswort, a
plant high in copper, was first used to help combat AIDS. Also in
the United States, the very rapid spread of AIDS had been linked
to inadequate copper in the food chain — perhaps due to the advent
of plastic plumbing — caught the FDA on the hop. They had always
assumed that most people got more than enough copper in their diets
and found that when they tested AIDS sufferers in particular, they
had only one twentieth of what they should have had (Acres U.S.A).
Johnes disease, a simple bacterial condition also needs a copper-deficient
host.
I
realized that my management of CAE was working and about as bloodless
as it could be, but still a nightmare. Others were not so lucky.
A certain breeder who was obeying all the rules about separate herds,
sheds, etc., rang me to say that yet again her goatlings had come
up positive. I asked how much copper she was feeding: "None, everyone
told me not to listen to you." I suggested that she take some copper
and see if the goats were interested. She took out an enamel pudding
dish full of it and 11 goats stood and ate the lot — after that
she believed me.
When
the copper level tests were done on my herd, I had about one third
showing "big knees." Alan Clark and I confidently expected them
to show low calcium/magnesium levels as it appeared to be an arthritic
condition. To our surprise, they only showed low copper levels,
even though I was supplementing with a small amount of the mineral.
From these tests, we established the lower level of copper supplementation.
I later raised the levels slightly in the diet after reading information
from Japan that dark haired people needed six times more copper
than those with fair hair (I ran predominantly black British Alpines).
Over the ensuing ten years, while fighting to eradicate CAE from
a fairly large herd of dairy goats, I had no lateral spread at all.
The only transmission of the disease was by milk and/or colostrum.
My goats have a minimum of one teaspoon of copper sulfate a head
per week, this is run through the feed on a daily basis as suggested
in this book.
Because
of having to make my living from milking, I could not afford either
to run a double farm (difficult if you are single handed) or wholesale
slaughter. I had to do the best I could, which was to run a mixed
herd. This I did for 10 years coming up to 1989 — and probably before
that without knowing it. By the time I quit full-time milking in
1992, the herd had been CAE-free for two years.
I
have used positive bucks over negative does and vice versa. I have,
from the time that I was able to afford testing the whole herd,
tried to feed positives together and negatives likewise. Even that
came unstuck when someone gave me a negative which was not truly
negative; she spent her youth and adolescence feeding with two negatives.
In spite of that I have only had one case of a grown animal becoming
infected and it was not from the supposedly negative animal. It
was doe who managed to raid the bucket into which I put the first
squirt of milk from each doe taken off before I start milking. I
was called to the phone and, to my horror, when I returned I found
she had slipped the chain and had milk all over her face. Two months
later she tested positive having had, prior to that time, negative
tests and two negative kids. She and another doe that was accidentally
infected at birth were the last two before the herd was clear.
Probably
the biggest cause of lateral infection is via milking machines.
An article from La Chevre quoted in the British Goat Journal
said that it had been discovered that for a few milliseconds, when
the clusters are first put on, the pressure in the udder is lower
than that in the clusters and the milk is sucked back into the udder.
The newest cow clusters in Europe are now being fitted with anti
suck-back shields to prevent the spread of disease. In this country
Diversey now markets a small valve that does the same task.
So
it is absolutely essential that commercial herds know the status
of their goats. Negatives must be milked before positives.
It is an ongoing program which must be kept up-to-date until the
herd is totally free of the disease. Sadly, every country in the
world, except apparently South Africa, has CAE. A run down but beautifully
set-up commercial concern I saw in Sussex, England in 1988 had reached
the stage where 50 percent of the milking herd showed clinical CAE
(big knees). Status was totally unknown as was the fact that they
had CAE at all. I had the unenviable task of telling them to get
the vet in and start testing. The new managers (of two days) knew
all was not well, but did not have the slightest idea of the cause.
Once they institute a control program, a couple of years should
see the situation well on the way to being clarified.
One
excellent preparation called VAM (Vitamins, Amino Acids and Minerals),
which is an injection available in Australia, enabled me to nurse
my positives along so that they could bear their kids. It kept them
going and feeling reasonable well when all else failed. In normal
goats a two cc intramuscular injection lasts about two months. The
CAE goats needed it weekly in some cases, but it was worth it to
see them enjoying life.
Testing
in the United Kingdom is easy compared with Australia because the
test for Maedi Visna in sheep (a disease which is not in
Australia yet, thank goodness) can also be used for CAE. The sometimes
outrageous prices asked here for CAE testing have been a great setback
in bringing the illness under control. Particularly in Victoria
where there has been no Department of Agriculture sponsored scheme,
as there is in other States.
Catching
the kids may be time consuming but, in all cases of straightforward
births, it seems to be successful. If the birth has complications
and the placenta is broken inside the doe, there is a very real
chance that CAE will have been passed to the kid before it is born.
I know of two cases where the first one or two kids were "caught"
quite successfully, but the last kid was born after much difficulty
and it was infected — one was the doe referred to earlier in this
section who was supposed to be clear. Kids from such births should
be assumed to be positive until they are proven otherwise. Tests
must not be done on kids under six months who are fed milk from
negative does, and not before twelve months for kids fed sterilized
infected milk. The latter must not be tested until at least four
to five months after they have stopped having the sterilized milk.
The dead virus will cause passive immunity which will show up as
a positive in any test for CAE done before that time.
Kids
must be kept separate from positive adults or those of unknown status
until they are four or five months at least. Kids that suckle their
dams must never be run with positives or goats of unknown status
— one cannot be quite sure that they may not suck from the wrong
doe.
Care
should be taken at shows to make sure the judge’s hands are washed
between handling each goat’s udder. Leaders must open their goat’s
mouths for the judge and, if you are leading up someone else’s goats,
make sure you wash before and after doing so.
Tattoo
letters and numbers must be disinfected between doing each animal,
particularly if they are goats or kids from another farm. Make sure
that injection needles are not used on more than one animal at a
time — particularly when testing for CAE — regrettably, I once had
to tell a vet to use a fresh needle each time when bleeding the
goats. These are all possible methods of spread.
In
1991 a further and very disturbing factor emerged, the ELISA test
commonly used in detecting CAE picks up a similar signal if the
tested goats are sick (with something other than CAE). Only after
careful and exhaustive re-running of tests was this fact verified
and so saved some perfectly sound goats from death. At last tests
on milk are being suggested, the virus was first detected in milk
so it is feasible and would perhaps stop any anomalies arising from
using the ELISA test.
Catching
Kids
Make
arrangements for a special kidding area into which all positive
does or those of unknown status are removed the moment they show
signs of kidding. Have chains with snap hooks at head height on
the wall to which the doe can be attached so she cannot reach the
kid to lick it. Occasionally kids arrive rather fast. Have clean
newspaper ready, catch the kid in it as it is being born and remove
it as far away as possible — preferably out of earshot of its mother.
Dry and clean the kid with the newspaper, rubbing it quite hard
as this helps the circulation, then put the kid away to await its
first feed. Some people suggest bathing the kid, I have never done
it and all my "snatched" births have been successful.
If
the kids are taken away in this way, so that the doe cannot see
or hear them, it helps stop her fretting. Some people leave unwanted
buck kids on positives, but I think it is unwise to take the risk
if they are running with negative does as they might suck the wrong
doe. One of the sadder aspects of CAE is that the does cannot ever
suckle their kids.
Feeding
Caught Kids
I
have tried feeding kids cow’s colostrum, but felt that it was really
of doubtful value (and it too, can transmit disease) as immunity
is not conferred by any animal save the mother of the kid concerned.
Heat treating positive colostrum is a tricky business and it only
needs one mistake for the infection to be spread all over again.
I
learned to make the first drink from either unpasteurized milk from
a clean negative (of at least two generations), or pasteurized milk
from positive does, which we all had to do at first. To the warm
milk I added one teaspoon of cod liver oil and half a teaspoon of
liquid seaweed concentrate (I use Vitec Fish and Kelp Stock drench
or the product that Maxicrop put up — these do not have any additives
and are the safest). The kids passed their first manure very quickly
and never looked back on this regimen and at least there was no
chance of some odd disease being contracted from another animal’s
colostrum.
Heat
Treating Milk
This
can be done fairly easily by raising the milk to 165 degrees fahrenheit
and keeping it there for five seconds. Use a cooking thermometer
and suspend it over the pasteurizing pan so it is in the middle.
My first whole season of feeding kids from positive does by this
method resulted in all negatives. As mentioned above, do not test
until the kids are a year old since before that they could show
"passive" positive even though they are not infected. Unfortunately,
far too many kids were killed until this fact was pointed out by
a vet.
Even when the herd has reached negative status, I think it would
be very unwise to feed pooled milk to the kids. They should be fed
from a select few tested does who are several generations clear.
We did, after all, hasten the spread of CAE, which has quite definitely
been in Australia for nearly 40 years at least (since 1960 if not
before), by feeding pooled milk. In a situation where does always
fed their own kids, it could not spread so far or fast.
I
remember one quite beautiful black doe that I was given, an excellent
milker who showed absolutely no signs of ill health at all, no "big
knees" (I would not have known what it was anyway at that time).
I always used her milk to feed the kids. When she was nine years
old the goats came under great stress from nitrate poisoning and
up her knees came. Too late. Most of the kids had been destroyed
because we soon learned that any kid whose knees came up — usually
at six months or so — became an unthrifty adult, so they were never
allowed to live once it happened.
The
above story bears out what one of the vets who researched CAE here
said to me. He postulated that, in herds where the management was
good and there was no stress, he felt that up to 90 percent of the
goats could be positives and show no signs until they died and possibly
not even then. Many people tell me that they have never seen any
signs of the disease so they do not test. But, as soon as those
goats are sold to another farm — no matter how good the management
— the stress of moving (if they are positive) activates the virus
and they start to show big knees, lung troubles, hard udder or whatever.
Never
buy a doe unless she is negative, with a vets certificate, unless
she comes from a tested herd. A test done while a doe is pregnant
is likely to show negative regardless because being in kid often
temporarily suppresses the virus in the blood. Does should not be
tested until at least two months after they have kidded. When I
needed to buy two goats here, as I had lost most of mine in the
move, I did not heed the above information. The doe I purchased
was from a reputable stud, all advertized as being CAE free. I had
to kill her and her two kids and by that time her milk had infected
two more.
I
have not gone into details of the disease from the clinical point
of view to avoid confusing goat keepers with too much information.
Only one fact should be borne in mind; for humane reasons, any goat
that shows big knees should immediately be shot or otherwise euthanized.
The vet who destroyed six of my positives some years ago emphasized
this fact, because the post-mortem examinations showed that the
first place to be affected by the virus is the brain (neurotic goats
nearly always turned out to be positives), the second sign was spinal
lesions and the knees were the last to come up. So by the time the
animal’s knees showed the effects of the disesase, the goat was
already suffering quite badly.
Bucks
and CAE
It
is obviously important that bucks do not suffer from CAE, therefore
they too should be "caught." However, the vets in Western Australia
who first isolated the virus and found that it was transmitted in
the milk now say that it is not passed on by bucks and positive
bucks may be used over healthy negative does. This bears out what
I have found, I had to use positives over negatives and vice versa
because I could not afford to do anything else. There was never
any transmission of CAE at the time of mating in either direction.
This is a merciful dispensation of nature, otherwise we would have
lost even more valuable genetic material than we have already. Obviously
we want our bucks to last well into double figures, which is what
used to happen before CAE, so they should be reared CAE free.
First
Generation Negatives
In
my mind there is no doubt that these animals are not quite as robust
as the later generations, especially if both the parents were positives.
They have to be looked after extra well, after all, it is a small
price to pay to be free of what is financially, emotionally and
physically a ghastly illness.

Unfortunately
we cannot be like David Mackenzie and say there should be no health
problems since he had the ideal environment for his goats — three
miles of coast line and plenty of room. In those circumstances and
with the feeding he suggests, illnesses would be at a minimum —
even in the United Kingdom few people can aspire to similar surroundings.
In Australia we do not have a hope of emulating him. Here our goats
have to face a series of soil deficiencies and imbalances and farmers
— of milking goats particularly — have to be very good at their
job to keep the goats healthy and productive.
Goats
in the wild travel vast distances to find the feeds they want and
only suckle their own kids, like their sisters of the meat and fiber
sorority, for about three months or less. In these circumstances
nutritional stresses should not occur. But those who have brought
feral goats into farm situations will tell a very different story,
with goats dying by the hundreds in some cases.
The
more that we know about the effect of nutritional stress causing
disease conditions, the more do I feel that hereditary conditions
are not quite as frequent as we are led to believe. Several conditions
hitherto considered hereditary are now found to be due to nutritional
stress at one stage or another.
In some cases the stress is caused by overfeeding; this was much
more common about thirty years ago — acetonemia was the most dreaded
illness then, but it is hardly ever heard of now. Generally, a lack
of the correct minerals in the right amounts is the culprit.
Sick
land with calcium, magnesium and/or sulfur deficiencies coupled
with a pH so low that the acidity of the soil inhibits the uptake
of trace minerals, is also a medium where dung beetles cannot do
their task of taking animal manures below the ground. So the result
is a double-edged sword, increasing worm burdens suffered by goats
who are not receiving the nutrients they need from their grazing.
In other words — disaster. In my experience, it takes three years
for people to realize the truth of this and then they have to take
steps to improve their land.
Goats
are by nature browsers, worm larvae and eggs are found in wet pasture
not up trees, so goats in their natural state would not encounter
many worm problems. The same happened in Africa when giraffes were
first confined in game reserves and were expected to eat grass instead
of the trees they preferred — I’d rather drench a goat than a giraffe.
Nursing
In
any illness good nursing and confidence of the patient in the nurse
are generally more than half the battle. This is the great argument
in favor of well-handled goats. I have bought in poorly handled
animals who still, several years later, shrink from human contact
(except at milking time); to these animals, drenching or any treatment
is an experience so traumatic that often it seems to do more harm
than good.
Treatments
Most
of the treatments I suggest have been discussed with or emanate
from the veterinary profession in many countries. Papers given at
various conferences world-wide have yielded much information. Some
are learned from an older (and wiser) generation of farmers. For
example, the late Mrs. Maura Mackay of Glenroy (Angora and Saanen)
fame should have the thanks of countless dairy farmers (both goat
and cattle) for teaching us how to use dolomite as a cure, control
and preventative for mastitis.
Many
people do not notice an animal that is off color until it is really
ill — and quite frequently it is often too late by that stage. The
goat that is lying down when all the others are standing eating,
or is lying apart from the others — that is the animal that should
be checked. My method of shedding ensures that I immediately see
any goat that does not dive straight into her food night and morning,
or any goat that has a dirty back end — both indicators that all
is not well. Teeth grinding, yawning and repeated stretching tells
the goat farmer that the animal has a pain somewhere and trouble
will soon follow if steps are not taken to rectify matters. It is
not fair to a vet to allow the goat to reach a semi-moribund state
and then expect a cure. Goats often give up when they feel ill and
then it will very likely be too late by the time the vet arrives
unless some supportive measures like B12 and vitamin C injections
have been used.
I
use vitamin C instead of antibiotics for infections, whether bacterial
or viral. If it is used in large enough quantities, it works for
viruses, unlike antibiotics, and it has no side effects. Antibiotics
are used to offset the secondary (generally bacterial) infections
which usually occur after a viral infection. Much of the work with
vitamin C has been done with friends who are vets and we have been
amazed at some of the results when all else has failed.
I
have had unfortunate experiences with some antibiotics, but in those
early days no one, vets included, knew the right amounts for goats.
They were assessed like sheep, as the weights were similar, until
several very unlooked for results made us all realize that we had
to have a totally different yardstick for goats. All antibiotics
have their side effects and I prefer not to use them, although one
vet I know of uses vitamins with them and gives good reports of
the results. I do not use immunizations — and have found no need
to do so — that is my choice. Like David Mackenzie, I see no use
for them in properly looked after goats.
It
is important to learn how to properly give an injection to a goat.
The University of Melbourne taught me years ago never to
give a goat an injection in the rump or rear of the back legs. This
followed a post-mortem on a goat that died from an antibiotic which
had been injected in her rear of the legs. I was told by a butcher
that animals have a gland around there, and very few people even
know of it. The needle had evidently hit it and the leg was already
atrophying and the back leg would have eventually become useless.
The vets told me that for intramuscular injections, the muscle in
the side of the neck was always absolutely safe and never to give
any injection without thoroughly cleaning the site first.
Intravenous
injections are often very good if there are two people present,
one to hold the animal still and one to inject. But if the goat
is in a state of shock, or when the veins collapse, it is no use
trying to find one. This frequently happens in the case of snake
bite.
The
bottom line in any sickness is good nursing, keeping a goat warm
and as happy as possible under the circumstances. This can pose
problems because sometimes a goat will fret if removed from its
companions. A sick bay within sight and sound of the other goats
is sometimes a good idea — other times they are better totally segregated
— one has to play it by ear. It is no good just giving the animal
the appropriate treatment and leaving it to sort itself out, they
need care and reassurance.
Abscess
An
abscess can be caused by grass seed working out from the back of
the mouth or an organism entering a break in the skin. The body
tries to expel the foreign matter and an abscess forms in the process.
It can be hurried up by hot fomentations, or occasionally extra
vitamin C, but it is really best to leave it to come to a head naturally.
The vitamin C can be given as an injection of three grams for two
days running which speeds up the process by detoxifying the poison.
When
the abscess comes to a head and breaks, clean the pus away — burning
all material used in the process. Wear rubber gloves if you have
broken skin on your hands. Then syringe out the site with a mixture
of 10 percent copper sulfate and water, trying to remove the core
of the abscess. Allow it to drain and close up of its own accord
and be careful it does not become fly blown, Flints oils or septicide
ointment are both good preventatives against fly strike and the
wound can be filled with either.
If
an abscess is allowed to come to a head naturally and cleaned out
as described, the healing will be very fast indeed. If however,
the abscess is lanced before it is ready, a very nasty mess ensues
which often takes several weeks to clear up.
Acetonemia
This
used to be the goat disease when I started goat keeping at the beginning
of the 1960s. It was almost endemic in studs where goats were fed
a great deal of high protein feed without the balancing carbohydrates
and dolomite. This was done to encourage high production and many
of the goats were over fat and under exercised.
Signs
are misery, irregular cudding, lack of appetite, dark, sticky looking
droppings and breath smelling of pear drops. Remove the cause and
treat first as a cobalt deficiency, giving two cc of B12 by injection
three days running and a dessertspoon of dolomite daily for three
days. Rethink the feed program and see that the goats are exercised.
Goats
that are heavily hand fed become lazy about going out to look for
grazing, a bit of mild starvation will usually give them the idea.
Goats that regularly receive the correct minerals and whose food
does not exceed 14 percent protein should not succumb to acetonemia.
Anemia
This
is due to a shortage of hemoglobin, or red blood cells. In any country
except Australia this could mean a lack of iron in the fodder. In
Australia most soils have adequate to too much iron so it will mean
that the anemia will be due to a lack of copper. Without copper,
iron cannot be utilized (see section on copper). The other causes
could be liver fluke, blood-sucking worms like barbers pole (haemonchus
contortus) brown stomach worms (ostertagia) or bleeding
from an internal injury.
The
most obvious sign of anemia is goats that are lethargic and off
their feed. Examine the membranes of the eyes, they should be a
good deep pink to red but will possibly be a rather pale pink to
white. Checking the membranes of the eye should be a weekly, if
not daily, part of good husbandry.
If
lack of copper is the cause of the anemia, this can be fairly easily
adjusted if the animals are fed copper through their ration as suggested
in Chapter 6. But a worm count should also be taken because blood-sucking
worms kill goats, especially kids, very quickly indeed. Kids with
barber’s pole infestation will be found to have chalk white eye
membranes. Act very fast; administer B12 injections (one
cc) every four hours, the mildest possible worm drench as a very
strong drug could kill at this stage, and for the next three days
provide an iron tonic (ironcyclene or similar). Give them
seaweed meal ad lib which will go some way to building up the copper,
which should be in the feed as already described. Worms and fluke
are not interested in hosts whose copper requirements are being
met.
Uncharacteristically
low butterfats are often due to anemia, they are not always hereditary.
A failed milk test is quite often a goat owner’s first clue that
something is wrong. I was told years ago always to give the goats
a course of vitamin B12 injections coming up to a milk test (where
butter fats are recorded). Sometimes I did it, not knowing why and
wondered if it made any difference, but obviously the person who
had told me found that it did.
Arthritis
Beginning
from the late 1970s until now, we have come to equate this condition
with CAE. However, goats can and do get arthritis that does not
owe its origin to that virus.
Signs
are creaking joints (audible a few feet away) in mild cases, heat,
stiffness and sometimes swelling in the joints — knee and stifle
in particular. Arthritis is caused by nutritional stress due to
an imbalance of the minerals in the feed. When it occurs in animals
that are already receiving the correct amount of dolomite, it will
be due to insufficient vitamins A and D and/or copper and/or boron
— all are needed to assimilate calcium and magnesium.
One
of the papers presented at the Tours International Conference of
Goats also implicated a lack of copper as a predisposing factor
(copper bracelets on horses have had good press). The lack of A
and D can be due to reasons suggested in the section on those two
vitamins (see Chapter 10). Lack of boron necessary for vitamin A
and D absorption will be due to a shortfall in the soil. One teaspoon
of borax between twenty goats once a week supplies enough boron.
Treat
arthritis by removing the grains from the ration initially — give
plenty of good quality grass hay, green feed and a little chaff
and bran. Give vitamin A and D in some form regularly and include
seaweed meal ad lib for the boron and copper. Cider vinegar is also
a great help and should be added to the feed, or let the patient
help itself. As much borax as will adhere to the tip of a finger
can be fed daily. These days, in any case of arthritis, the goat
must be tested for CAE and if it is positive no treatment will work.
Arthritis
— Infective/Septic
This
is caused by an organism that has gained entry through a wound,
or possibly the navel cord (which may not have been properly disinfected
at birth), or, more rarely, following mating to an infected animal
— this can work either way. It usually takes about six weeks for
the organism — generally corynebacteria — to show up. It happens
very suddenly, with arthritic symptoms and a high temperature. Very
occasionally high doses of antibiotics work, but this bacteria is
notoriously difficult to treat, especially when it is in a joint
where it can cause irremediable damage. Vitamin C therapy started
immediately when signs are observed could possibly be successful
— give a kid five grams (10 cc) intravenously if possible, if not,
inject in the muscle and repeat every 12 hours. Give half a teaspoon
of cod liver oil every two days, preferably by mouth. Good nursing
procedures and giving afflicted adults twice the above dosage may
work. Make sure the patients have unlimited access to seaweed meal.
Infective
arthritis, whether from the navel or otherwise, is an unfortunate
condition because it lies dormant for quite a long period while
the causative organism is already doing damage. I bought a kid from
interstate which was seven weeks old before a navel abscess showed
up closely followed by infectious arthritis. We did not know about
vitamin C in those days and the available drugs had little if any
effect. It is also probable that it would have been too late for
vitamin C to work. Its navel cord had not been disinfected and it
was born in an old sheep yard, a frequent source of infection.
I
learned about the venereal variety when a doe, who I afterwards
learned had aborted previously and was in poor health, was brought
to a good young buck for service. The first I knew was several weeks
later when the buck suddenly became crippled with arthritis in all
four legs. Everything was tried, and eventually he was put down
and a post-mortem was performed. The cause was then discovered,
corynebacteria and a swab of the last four does he had covered revealed
the culprit, who appeared perfectly well. She did not hold to the
service and was probably incapable of conceiving.
Do
not let a doe come to your buck if there is any history of abortion
or similar trouble. Insist on a clean swab (a swab can only be done
when she is in season) before she comes back.
Avitaminosis
This
condition literally means that the goat has run out of essential
minerals and therefore vitamins rather suddenly. Unusual lethargy,
unwillingness to move, eat or drink are the first signs of this
ailment. Examine the membranes of the mouth, according to the severity
of the condition they will either be streaked with scarlet lines
or be a bright pillarbox red all over. Give the affected goat a
dessertspoon of dolomite, the same of vitamin C, and two ml of VAM
in the muscle — also give seaweed meal straight into the mouth and
leave it for the animal to take as much as it wants. Usually this
is enough, but in a severe case the treatment may be repeated eight
hours later. I first met this affliction in a doe belonging to a
friend who had bought the minerals for it but had not fed them.
I suggested that she weigh the minerals, put them out for the goat
and see what happened — the goat in question ate a pound without
stopping and recovered almost instantaneously.
Bent Leg
(Kids)
This
is caused by a bad calcium/magnesium to phosphate imbalance which
is almost invariably produced by overfeeding with milk. In one case
where I was consulted a kid was being given 12 pints of milk a day
— far too much. The bones (and the kid) grow very fast when this
happens, too fast for the bone to form as it should — hard and flinty.
The imbalance makes bones soft and porous, so the weight of the
body causes the legs, usually front, to bend.
To
treat it reduce, preferably stop, the milk intake, (see Chapter
8 on the reasons against overfeeding kids with milk) to about a
pint a day at most. Give a teaspoon of cider vinegar daily and some
form of cod liver oil, (A and D injection or by mouth). Grain must
not be fed, only a little oaten chaff, bran and good grass hay.
Dolomite must be mixed in the feed, a teaspoon a day, and the same
for yellow sulfur — no more. Seaweed meal should be obtainable ad
lib, and a gram of copper a day in the feed (dissolved in the cider
vinegar). If caught in time, the legs usually straighten by the
time the kid is full grown.
Bent
Leg in the Newborn (Contracted Tendons)
The
kids are born with their front legs bent under them so they stand
on their toes — this can affect either one leg or both legs. The
impression is that the flexor tendons are pulled up too tight, which
is exactly what has happened. In extreme cases the leg or legs assume
an "S" bend. I used to think this was just one of those things that
would right itself — it usually did — eventually. Some authorities
list it as being hereditary, but it is not. Drought or overhead
main grid power lines can both interfere with the correct synthesis
of vitamins A and D.
My
last untested (for CAE) doe to kid produced two does with badly
contracted tendons. I gave them the homemade colostrum mentioned
in the section on CAE. Within a few hours, the kid’s legs had straightened
completely instead of taking the usual week. The next doe to kid
was from the same place as the first one; both had ongoing vitamin
A deficiencies, possibly due to the fact they were reared under
power lines. Again the kid’s front legs were deformed and the A
and D worked just as fast. In this case the mother was able to feed
her own kids, so I gave each one half a teaspoon of cod liver oil
straight in the mouth.
Recently
a friend called me with a six-week-old kid that had a contracted
tendon in one leg only. It was so bad that the leg was twisted right
around. I felt that in one leg there could be a deformity, but suggested
that she try the A and D. To her amazement (and mine) the kid came
good in a few hours.
Goat
farmers should make a note of does who produce kids with this complaint
and give them a cod liver oil booster about three weeks before kidding.
This should prevent contracted tendons from occurring. The does
could be given either A, D and E injections, or oral cod liver oil.
Bent
Leg in Adults
This
is usually caused by a sudden increase in phosphate-rich feed resulting
in a possible withdrawal of calcium and magnesium from the bones.
The goat pictured here was given extra alfalfa hay coming up to
kidding because it was a particularly hard winter. The diet should
have been altered by giving extra oaten chaff, bran and little barley
with as much good quality grass hay as desired. I also recommend
the following additions to routine supplements:
- Give
1 tablespoon of dolomite with each feed for a week, then cut it
back to the regular dessertspoon
- 1
tablespoon of cod liver oil 1 pinch of borax in the feed twice
a week
- 1
cup of cider vinegar with each feed
- Seaweed
meal ad lib
Once
the leg starts to harden up, go back to the regular ration but avoid
sudden increases in rich feed.
Beta
Mannisidosis
This
is an hereditary cell storage disease, similar to Alpha Mannisidosis
in Angus cattle. The cells cease to function properly and store
material that should be expelled until finally the system, loaded
with toxins, breaks down. The brain cells appear to be the worst
affected. Up until the present time in Australia this problem has
mainly been found in Nubians and a few Saanens. The signs are usually
fairly conclusive and it shows up in kids as spasticity. There appears
to be no known cure and affected animals usually live no more than
a few weeks.
Owen
Dawson visited one property where Nubian bucks had been used over
ferals for meat production and there was a very high proportion
of spastic kids. Thus it would seem that it possibly is not necessary
for both individuals to carry the disease — perhaps it can be transmitted
by one animal. Certainly in one Nubian stud that I knew well — from
a herd where the status of all the animals was known — the transmission
was very uneven, often two positives did not produce a spastic kid,
then, or in later generations.
Beta
Mannisidosis appears to be another of those inconclusive conditions.
It is thought to be hereditary and to need two carriers. But considered
opinion in many cases links this condition to management. In studs
where goats are well looked after it has rarely been a problem;
lack of viability due to inbreeding may have triggered it off originally.
Blackleg
— Clostridium Feseri (Chauvoei, Bacillus Chauvoei and B.
Anthracis Symptomatis)
This
clostridial disease is caused by a scratch or surface wound, often
on old sheep country, that has not been disinfected properly — again
because it may have been too small to see. The first lesson the
vets I worked with in the United Kingdom hammered home was that
a wound must be properly disinfected at once. The vets used peroxide,
iodine, disinfectant (Lysol in those days) and said that if all
else fails alcohol — gin, whisky or whatever (a 10 percent copper
sulfate solution is also very effective). This disinfectant must
be syringed into the wound if necessary, and all dirt removed if
possible.
Blackleg
is rare in goats in Australia and is reported in Hungerford’s Diseases
of Livestock to be incurable. As of 1990 only three cases had
been reported here, two indirectly due to five-in-one vaccinations.
In the first case, a dirty needle was used, and the other followed
two days after a routine five-in-one vaccination where every care
had been taken. The vet concerned in the latter case said that in
the future he would not recommend this type of vaccination for goats,
but rather would use only the two-in-one (tetanus and enterotoxemia).
The
third case followed a goatling being cut along the side by barbed
wire on an old sheep farm. The wound was not cleaned and three days
later the first signs of blackleg appeared. The goatling was saved,
but it took three weeks because, when the owner first rang, I did
not realize there had been a wound. So I imagined it to be a bite
and not Blackleg. I advised a small injection of vitamin C, five
grams, which kept it alive but meant the cure took two weeks. I
now know that the treatment was inadequate and the suggestions below
work in hours not days. This goat was the fourth case I knew of
and happened on my own farm. I felt the goatling had pierced her
leg just above the stifle joint, but there was nothing visible.
In
Blackleg the limb, generally a rear one, swells to grotesque proportions
and the goat is in great pain, usually lying with the leg sticking
straight up in the air due to the swelling. If no action is taken,
shortly afterwards the head starts to swell and the goat will die
very soon from the enormous pressure of the swollen parts, which
rupture and turn black, giving the disease its name.
Do
not try injecting into the neck as usual, because Blackleg makes
the whole body super sensitive. Inject straight into the affected
limb repeatedly (every few hours) with 25 grams of vitamin C, give
good supportive nursing and an injection of VAM and B12 in the neck.
As soon as the goat is eating again provide ascorbic acid powder
in the feed. Continue to inject the affected limb with vitamin C
until it goes down (about 24 hours). Find and disinfect the cause
if possible.
Bloat
This
condition is caused by potassium and magnesium being unavailable
— generally in an overly rich pasture where clover is dominant.
On a minerally balanced farm, the clover and grass are equal and
bloat does not arise, however good the year. Tallow is another cause
of bloat in kids which have been fed a milk replacer that contains
processed or just plain tallow. Both stop the kids from obtaining
the necessary nutrients from the milk and they die of bloat (and
starvation). No therapeutic measures work when bloat is caused this
way. This is because the tallow coats the inside of the alimentary
canal and no nutrients can be absorbed.
In
bloat the goat’s abdomen will be much distended, especially on the
left side. If the goat is still able to walk, drench a quarter of
a pint of cooking oil down the throat, then exercise while massaging
the sides. This usually persuades the wind to be passed from one
end or the other. As soon as the goat is relieved, give a dessertspoon
of dolomite mixed in half a pint of cider vinegar which will help
replace the missing magnesium and potassium.
If
the animal is down and in distress, call a vet immediately because
the pressure in the abdomen will quite soon stop the lungs and heart
from working. The vet will release the gas with a trochar (a sharp
hollow surgical instrument with a retractable center) allowing the
gas to escape. The incision is made four fingers width behind the
bottom of the ribs on the left side of the goat as it lies.
If
the vet is unobtainable, a sharp, pointed knife will work in an
emergency. Disinfect first, insert the knife point until the gas
starts to escape, twist it slightly, remove the knife, and close
the wound once the distension is relieved.
Again,
a drench of seaweed meal with dolomite and cider vinegar (about
10 fluid ounces altogether) should be given as soon as possible
to build up the magnesium and potassium in the system.
With
bloat, prevention is easier than the cure — or death. Have the paddocks
analyzed as soon as possible and top dress with the necessary lime
minerals. Do not use chemical fertilizers under any circumstances.
If the bloated goats are still feeding on the paddock that caused
the trouble, make sure that all the necessary minerals are in the
ration. Seaweed meal should be ad lib as usual.
Blood in
the Milk
Unless
caused by a blow from another (usually horned) goat or animal, this
usually occurs in first lactation milkers when the udder is expanding
rather fast. It is the result of ruptured blood vessels in the udder.
If accompanied by viscous or offensive smelling milk, treat as for
mastitis (see mastitis below). Treatment is to give at least a teaspoon
(five grams) of vitamin C powder orally and six cc by injection.
Repeat the oral dose daily until the milk is clear. Milk with blood
in it must, of course, not be included in a contract. To check that
the milk is clear, leave it in a glass container for a 24 hours
— the blood will be seen as a dark line through the bottom of the
glass.
Boils
See
Abscess.
Bottle Jaw
This
is a hardened swelling under the jaw and is almost invariably caused
by worms or liver fluke — occasionally it will also arise in cases
of extreme debility. Dealing with the worm problem usually clears
it up, consult the section on worms. If this is not the cause, attend
to the goats general health. If the goat’s CAE status is unknown,
have a blood test taken. If the goat is positive it can only become
worse.
Broken Bones
An
ordinary bone break where the skin is unbroken is fairly easy to
heal in a light animal like a goat. If the fracture is compound
(where the bone protrudes), call the vet quickly.
When
splinting, pull the limb out carefully so that the ends of the bones
meet and try to set it in that position. Plaster of Paris is not
really a success on small animals, as it is difficult to keep dry
and tends to be too heavy. A leg can easily be splinted — first
apply a soft bandage the full length of the affected limb. It is
usually better to bandage the whole leg, especially if the injury
is above the knee or hock. Then put on the splint, the side cut
out of a plastic bottle, a metal "ladder" (obtainable from a vet),
split bamboo or other light wood, all work equally well. Then bandage
the splint in place and sew the end of the bandage. Do not use safety
pins, clips or knots, they can end up inside the goat or be undone
(or both). Bandaging is an art, too loose and it comes off, too
tight and the limb drops off. Experience teaches you, so check an
hour later to see that pressure has not built up because the bandage
is too tight.
Years
ago I treated a two-month-old kid who was staying on my farm as
described above and she was returned, unblemished, to her owner.
Standing beside the animal at a show years later, I told the owner
to feel carefully down the lower part of the leg; she could just
feel a very faint ridge where healing had taken place and asked
me what it was.
Goats
are excellent patients; they never attempt to put weight on an injured
limb until the fracture is healed. It is best to keep them away
from long undergrowth while the splint is on, otherwise the leg
may become caught up and twisted. Do not keep the patient indoors,
it is better off leading a normal life. A healthy goat will be fully
healed in ten days or less. At that time remove the splint, but
leave the leg strapped up for another week as a support.
In
both cases, compound and ordinary fractures, add one 500 iu capsule
of vitamin E and three to five grams of oral vitamin C to the diet,
plus one teaspoon of cod liver oil a week. An extra teaspoon of
dolomite daily should also be given. Those who have comfrey growing
should feed three to four leaves a day to a kid and double or more
to an adult goat. If you can find comfrey tablets, give two a day
for a kid, and four for an adult until healing is complete — goats
will often chew the comfrey tabs up — otherwise crush them in the
feed.
Brown Stomach
Worms
See
worms.
Cancer
This
illness seems to be on the increase in all animals, probably for
many of the same reasons that it is increasing in humans. Goats,
like most animals, have a head start over us because they manufacture
their own vitamin C and are therefore never without it in the system
(see section on vitamin C in Chapter 10). Fluoridated
drinking water can be a contributory factor in cancer (see section
on magnesium in Chapter 10).
The
following treatment has been used successfully on a number of different
animals and would be worth trying. For an adult, give five grams
of vitamin C, with one cc of vitamin B12 (in the same syringe) daily
for two days. Then five grams of vitamin C alone by injection for
the next week. Add a dessertspoon of vitamin C daily in the feed
as well and continue the oral dose for another month if the cancer
has gone down.
In
addition, 50,000 units of vitamin A and 1,000 units of vitamin E
must be given daily for two or three weeks, then bring the dose
down to 10,000 units of vitamin A and the same vitamin E as before
for another two weeks (dissolving the capsules is the easiest).
Feed
the normal minerals as usual, including the copper (which helps
the immune system) and make sure seaweed meal is available on demand.
Andre voisin links cancer with lack of copper.
If
no improvement at all is noted in ten days, it is probably kinder
to put the goat out of its misery. Actual tumors should regress
totally in six weeks or less, but a large improvement in general
well being, lessening of pain and decrease in the size of the tumor
should be seen in about ten days or less. If so, continue with the
vitamin A, E and oral C daily until healing is complete.
Tumors
rarely disappear altogether and most often a small node is left
— keep an eye on it, if it starts to enlarge institute treatment
once more. Occasionally if the tumor is on the surface, it will
discharge like an abscess after a few weeks. This should be cleaned
up as suggested in the section on abscesses. This is preferable
to the tumor dissolving inside where it inevitably sets up toxicity
— hence the elevated doses of vitamin C to prevent any reaction.
During
treatment the goat should be on a grain-free diet with really good
plain grass hay and grazing. If the goat contracted the cancer on
your farm, analyze and top dress the paddocks with the lime minerals
as fast as possible.
Cane Toad
Poisoning
Give
vitamin C by injection and orally as for snake bite.
Car Sickness
See
travel tetany.
Casein in
the Milk
This
is a fairly unusual complaint. I have only met one case, but I understand
some does are prone to it. Obviously something is wrong with the
metabolism, but the cause is unknown. I never had another case once
I started to feed dolomite and cider vinegar regularly, so it is
possibly dietary.
A
hard lump forms in the teat, which is almost crystalline in appearance
when extracted. Massage it very gently down the teat and try to
persuade it through the orifice, causing as little pain and damage
as possible. Make sure the teat and hands are spotless, and give
a teaspoon of dolomite with the same of vitamin C powder each time
to counter the risk of mastitis.
Caseus
Lymphadenitis (CLA), Cheesy Gland
This
is quite different from a grass seed abscess, although it may take
a vet to tell the difference. The latter has been covered at the
beginning of this section. CLA is due to an organism — corynebacterium
pseudotuberculosis — which gains entry through a wound, often invisible,
or even from a grass seed. The abscesses are located on the lymph
system and usually start at the back of the jaw. They then follow
the lymph system down via the shoulder and underarm to the stifle
from whence they will form inside the animal, usually resulting
in debility and death. If the goat’s immune system is in good order,
one abscess is usually the only result, but should the goat be CAE
positive, with no natural immunity, the abscesses will, in my experience,
become endemic.
The
abscess starts as a flat hardening at the back of the jaw, developing
into a boil varying from the size of a dime to that of a tennis
ball, depending on the goat’s natural immunity. The treatment is
the same as described earlier in the section on abscesses, but extra
care must be taken in the handling of the pus from the abscess.
Rubber gloves must be worn if there is any likelihood of a skin
break in the hands and all material from the cleaning must be burnt.
A British Veterinary Society meeting in April 1990 classifies CLA
as a zoonoses, in other words, an animal disease that can be contracted
by man, often in a form more unpleasant than the original.
I
had an experience with an outbreak of this disease many years before
CAE became a problem. Every goat in the herd, about 15, produced
an abscess of some kind (often very small). From then on, even if
a new goat came with an abscess, my herd appeared to have built
up a natural immunity that lasted for years. The organism re-sponds
to no known antibiotic; exhaustive tests were done at the time of
that outbreak by veterinary researchers. They established that it
could sometimes be halted if measures were taken before the swelling
started — an obvious impossibility.
The
only measures I have taken have involved using megadoses of vitamin
C when the abscesses are internal. This does not stop them, but
it detoxifies the material from the abscess so it does not affect
the system — this, of course, only applies to CAE-free animals.
Many
years ago a woman rang me about a goat in the last stages of debility.
About three boils had burst on the exterior of her doe and then
started through the interior lymph system. The vet had diagnosed
them as being in the lungs and liver and advised putting her down
and I felt the same. The owner believed that while there was life
there was hope, so we decided to try vitamin C. The doe was given
10 grams intramuscularly daily for 10 days, with several injections
of two cc of B12 and good supportive nursing. I did not hear any
more and assumed the doe had succumbed until several months later
when I opened a letter and a picture of an absolutely blooming Saanen
doe fell out — she had made a full recovery.
In
some countries, the United Kingdom included, CLA is a notifiable
disease. It most often emanates from sheep, among which it causes
havoc because the abscesses cannot be dealt with or seen in the
wool. Exporters of goats may have to produce certificates of freedom
from the disease.
Several
attempts, mostly in South Africa where it has been a scourge to
fleece goat breeders, have been made to produce a vaccine. These
apparently have not been very successful. It was found that good
husbandry, such as avoiding deep litter situations and making sure
that the kidding yards were never on the same ground two years running,
were found to be far more effective.
Coccidiosis
This
is caused by an order of parasitic protozoa. There are several varieties
and each is species specific. In other words, each animal has its
own particular strain. Goats cannot catch it off birds or cats,
but birds can carry it from another of the same species. I personally
have doubts on that one since cases of this illness have arisen
— a specific instance was in a horse (which is rather rare) in the
United Kingdom and no other horses were known in the county with
the disease.
Apparently
many older goats can carry, and shed, the disease all their lives,
showing no signs of actually having it although a worm count might
reveal it. For this reason, especially in small goat operations,
kids are better segregated from the older goats for grazing. All
animals develop an immunity with age.
Signs
are ill thrift that does not respond to the usual measures and,
in severe cases of coccidiosis, blood will be seen in the droppings.
A test of the manure would confirm its presence. The drugs used
to treat the condition are severe and prevention is best. Rudducks
used to make an oral or injectable mixture of sulfadimidine for
treatment that was the least traumatic of those on offer.
I
prefer to make sure that all goats, especially kids, have access
to mallow (Malva) plants. This herb has the reputation of preventing
coccidiosis. Lately I have seen it listed as poisonous — it is no
more so than any other herb when eaten in excess. Certainly I never
had any more problems once I made sure it was growing round the
kid yards.
Also
it seems that properly supplemented stock of all kinds that are
receiving the right amount of copper do not contract coccidiosis.
This has been especially noticeable in the dairy cattle industry
where it was a scourge in calves. Owners report that since proper
feeding of minerals was started they have had no more cases.

Coughing
A
vet friend of mine used to be able to make a goat cough by exerting
slight pressure under the neck. It will be noticed that goats often
cough while being led if they have not been properly trained and
are pulling.
Persistent
coughing with no sign of fever can mean lungworm (see worms) and
any goat that has had lungworms is often left with scarred lungs
and will cough intermittently for the rest of its life. A course
of 500 units of vitamin E daily for one or two weeks could help
clear it up as this vitamin minimizes scarring.
If
the coughing is accompanied by distress and a high temperature,
treat as pneumonia — start treatment as quickly as possible. See
section on pneumonia.
Respiratory
problems traditionally affect goats or any other stock whose calcium/magnesium
levels are not correct. Have the paddock analyzed and do the necessary
remedial work.
Chilled
Animals
Adults
These
should be brought into a sheltered area and friction applied. Tie
a jute sack around them if possible. Hay must be offered ad lib,
food in the rumen is the goats natural way of keeping warm. If the
animal is hungry, cold stress can occur. Give a heaped teaspoon
of vitamin C orally and repeat two hours later, 10 cc injections
can be given if preferred. See pneumonia section for further treatments
if necessary.
In
spite of warnings to the contrary, a big teaspoon of brandy in some
milk — an old fashioned remedy — is still highly effective on occasion.
To heat up a chilled large goat, pour methylated spirit along the
spine and immediately rug it up and keep the goat warm. This remedy
has been used effectively to warm up animals — it depends on the
latent heat of evaporation.
Kids
These
can become chilled right through and will require a lot of attention
if they are to live. Put a finger in its mouth and if it feels cold
all way down, bring it inside by a fire (the bottom oven of a slow
combustion stove, with the door open, is good). Otherwise keep it
wrapped up. Give it a little warm milk with half a teaspoon of brandy
in it. I know this method is frowned on these days, but I have saved
countless lambs and several kids using it.
I
had a kid which fell into the irrigation channel in the winter.
I did not find out until feeding time that she was missing. She
had possibly been in the water for four hours and she was cold right
through. I gave her a teaspoon of brandy in milk, six cc of vitamin
C by injection and wrapped her up and placed her by the bottom oven.
She was still terribly cold when I went to bed, so I repeated the
treatment and took her, well wrapped up, along to bed. I wanted
to know how long it would be before she warmed up. It was two a.m.
when it happened and she finally relaxed and slept. She suffered
no ill effects.
Circling
Disease
This
can be a result of listeriosis, occasionally corynebacteria or a
nasal bot that has got into the wrong place, affecting the brain.
All these can make the goat one-sided and the animal then circles
incessantly. The gait is stiff and the animal walks with its head
stuck forward; post-mortem will confirm which was the cause. If
it was a bot, the meat will be quite safe to eat, not otherwise.
In any case, the ailment is incurable.
Cow
Hocks
These
cannot be classed as an ailment. Though for many years they were
considered hereditary — and probably were in the United Kingdom
originally where deficiencies were not so frequent as here. In Australia
all too often goats with perfectly straight back legs produce offspring
that become cow hocked with age. I have judged young kids with really
good back legs, only to meet them again a year later with their
hocks almost touching. A course of cod liver oil, (orally, as the
straight liquid, an emulsion, or as an intramuscular A, D and E
injection) should be given. Assuming, of course, that the goat is
receiving the correct minerals in its feed and has seaweed ad lib
available (see Chapter 6). Very young kids whose back legs suddenly
go weak can be given two or three cod liver oil capsules (as for
humans), which will effectively reverse the condition.
Cow
Pox (Goat Pox)
This
is a herpes linked illness. Small pustules appear on the udder and
sometimes around the tail and mouth. If unchecked it can spread
into large sore scabby areas. I have seen a buck who was literally
covered with pox and had to be treated with large doses of vitamin
C to arrest secondary infections. Like many herpes diseases, goat
pox is supposed to run a three weeks course. In my experience, if
goats are copper deficient it can become almost endemic.
To
treat the exterior, make up a wash of a tablespoon of copper sulfate
and the same of vinegar in about a pint of water. This can either
be administered from a garden spray bottle or rubbed on with a sponge,
the scabs will dry up and start to drop off. However, the disease
is more prevalent in colored and black goats whose copper requirements
are not being met. A British Alpine goat that I saw at a show, which
was slightly afflicted, was given half a teaspoon of copper sulfate
in her feed for two nights in a row and the condition cleared up
without any exterior treatment. First lactation does who, because
they had not been receiving the same amount of copper as the adults
due to lighter feeding when goatlings, always seem to be prone to
pox. Goat pox is occasionally infectious to humans. Most people
who milk by hand will have built up an immunity, especially if they
have had chicken pox.
Cystic
Ovaries
See
hereditary defects.
Dandruff,
Scurf
This
is caused by a deficiency — or excess — of iodine. In goats that
have been on the farm and have either been on the stock lick (if
fleece or meat) or ad lib seaweed meal (if milkers) this should
not arise. However, should goats arrive from another farm with bad
dandruff, check that the previous owner has not been using too much
iodine in some form. If seaweed is fed ad lib, goats with an excess
would not touch it, and if caused by a deficiency, they will make
it up from the ad lib meal.
Dandruff
can be a problem in fleece goats as it can affect the quality of
the clip, but more seriously, it means any goat that has it is below
par — read the section on iodine. In dairy animals dandruff should
be taken seriously as a sign of an iodine deficiency, as well as
being a nuisance if the goats are shown. Make sure that the stock
lick is out for the meat and fiber goats and ad lib seaweed meal
for the milk goats.
Deformities
Some
of these are hereditary and are listed in that section. If a kid
is born with a deformity (not contracted tendons, see that section),
it is probably hereditary; but if the condition develops later it
is more likely environmental (nutritional). Lack of magnesium can
and does lead to postnatal bone abnormalities, but this can occasionally
be caused by overfeeding of protein.
One
of the more usual and apparently hereditary deformities are twisted
and either under or overshot jaws and, of course, abnormal teats.
Some
years ago I sold a perfectly normal kid which, as usual with stud
animals, I had photographed first. A few years later I heard that
it had a developed a parrot mouth by the time it was two-years old.
I could not understand what had happened until later on when another
goat was brought back at two years of age for mating; so bad was
the deformity of the mouth that, until I checked the tattoo, I doubted
if it was the same goat. The doe duly kidded and came back to be
mated; this time I really thought I was seeing things because the
mouth was 100 percent normal. I asked the owner what she had done
to accomplish the miracle.
"Oh,
I knew you were always rattling on about dolomite, so I started
feeding it and the mouth gradually became normal in couple of months."
If
the damage is allowed to persist into old age, it may be incurable.
The cases I have seen in goats had been cured before the animals
reached full maturity — four years for a goat — but I know of a
14-year-old horse whose bones normalized after being fed correctly
for a year, so perhaps there is no time limit.
Dermatitis
This
is rather like goat pox in appearance. Symptoms are pustules on
the udder, which can also spread to other parts of the body as the
goat rubs the udder with her mouth, then scratches her face with
a foot, etc. Unlike goat pox, dermatitis seems to be fairly contagious.
Contaminat- ed teat dip cups, udder cloths and dirty hands can all
spread it. A copper wash made up of a tablespoon of copper sulfate,
the same of cider vinegar in about a pint of water and used as a
spray will help clear it up. An A, D and E supplement should also
be given along with half a teaspoon of copper sulfate with a teaspoon
of ascorbic acid in the mouth for two consecutive days. The normal
dose of copper in the ration should be given along with the above
as well. After two days the vitamin C alone may be given to help
recovery and avert secondary infections from the lesions.
The
condition is staph related and likes a copper deficient host, but
is not serious enough to warrant using a vaccine as is often suggested.
Goats appear to develop a natural immunity after a while. It is
noticeable that in herds with a high incidence of the complaint
the dietary copper is nearly always non-existent.
Diarrhea
(Scouring)
Intestinal
worms and infections, cobalt, copper deficiencies and enterotoxemia
are the most usual causes of this complaint. Other reasons can be
imbalance in the feed, paddocks too high in nitrate-rich feed such
as capeweed (already mentioned), and feed that produces acidity.
In small kids overfeeding of milk often causes mild scouring.
For
an adult a dessertspoon of dolomite, a quarter of a teaspoon of
copper sulfate and the dessertspoon of vitamin C down the throat
is always worth trying first, especially if there are no other signs
of illness. If the goat is listless, lacking in appetite or has
cold ears, suspect a cobalt shortfall and give two ml of VAM and
two ml of vitamin B12 intramuscularly. Quite often both or either
will clear the scouring up. Scouring is not (as is generally supposed)
always caused by worms. Hungerford’s Diseases of Livestock states
that unexplained scouring is often due to a copper deficiency and
sheep farmers have found that weaner lambs have responded to half
a teaspoon of copper and the same of dolomite quite remarkably when
all else failed. The same could be tried with young goats, the dolomite
should always be given at the same time (a teaspoon of dolomite
and a quarter teaspoon of copper sulfate).
If
intestinal infection is suspected, treat as for enterotoxemia (see
section on that ailment).
Scouring,
especially in kids, often kills by dehydration. Make sure they receive
enough liquids, two ml of Vitec Stock drench in 100 ml of water
would be safe, but no extra milk. In cases of adults with heavy
scouring, minerals are lost from the system and need to be replaced.
Drenching with 10 ml of the Vitec liquid, a teaspoon of dolomite
and cider vinegar made up to one pint with water, will help replace
them. This condition should not arise in animals properly supplemented
with ad lib seaweed, and/or the stock lick. In very severe cases
an electrolyte replacer may also be used.
In
any obstinate case of scouring, presuming it is not due to worms,
an injection of vitamin C should be given daily until it stops —
four grams for an adult, half the dose for a kid. All this is assuming
that the goats are on a tested and remineralized paddock.
Edema
This
is caused by the body tissues holding excess fluid and generally
occurs in the legs and along the sides of the abdomen. It is generally
found in grossly overfed animals, especially if the diet is too
high in protein and possibly salt. Years ago goat keepers tended
to feed far too much salt to their charges. If they are getting
seaweed meal ad lib, salt is quite unnecessary. More exercise, less
feed and a balanced ration with all the minerals in it should correct
the situation quite quickly.
Edema
of the Udder
This
is rare and has been mentioned in the section on parsley — usually
only elderly does are affected. The udder feels full but cannot
be milked. It is engorged with fluid and does not necessarily follow
just after kidding. It is very uncomfortable. One of the reasons
for this happening and it was a contributory factor in this case,
was the old practice of not milking a goat before she kidded. This
is very cruel and I never could understand why it was promulgated.
Does should never be forcibly dried up and, if the milk does come
down, milk them as usual. The colostrum does not come down until
the kids are born. Some vitamin C orally will do no harm, but the
sovereign remedy if obtainable, is parsley — give the doe all she
will eat. I found this remedy in Juliette de Bairacli-Levy’s Herbal
Handbook for Farm and Stable and luckily I had parsley growing
in the garden (see section on parsley, Chapter 10).
Encephalitis
This
is (I hope) very rare in goats. I have only had one case in 35 years
and she was not CAE positive. No one had any suggestions
as to how she could have contracted it and none of the other goats
were affected.
When
all the goats came in for their tea she was missing; I could see
her about half a mile up the farm standing quite rigid. Luckily
my son was home, so I got him to drive the Kombi, while I armed
myself with a bottle of injectable vitamin C and a syringe. We found
her with her legs stiff together under her, her back arched and
tail and head up rigid. We got her into the van, and I had given
her about 50 cc (in the muscle) of vitamin C by the time we got
her back to the shed. She soon collapsed and could neither move,
bleat, eat nor drink and I suspected meningitis.
As
it was rather late, we bedded her down on her side and made her
as comfortable and warm as possible. The vet came out first thing
next morning. The doe was still the same so we gave her 15 grams
of vitamin C in the vein of each front leg. Carol, the vet, told
her partner that I really had gone mad expecting to save the animal
as she had diagnosed encephalitis.
Within
two hours of the 30 gram injection of vitamin C the doe gave a bleat
— rather a pained one — and managed to drink a little fluid. I offered
her hot and cold water, molasses, and then in desperation straight
cider vinegar which she drank avidly. The next morning Carol came
out and repeated the first day’s dose of vitamin C and was very
much surprised to find her alive at all. By the evening she was
picking at green feed and hay, drinking as she wanted and could
now lie happily in the normal position instead of spread out flat
on her side.
The
last thing that night, when I went out to her, she staggered to
her feet and on the next day, although a little groggy, she seemed
fine. I continued the vitamin C orally, a tablespoon night and morning,
with dolomite and seaweed meal all in one dose for two or three
mornings. By the fourth day she was objecting strongly to being
away from the other animals so I let her resume her place in the
herd. There were no recurrences. She was quite a highly bred British
Alpine and lived on as though nothing had happened.
Enterotoxemia
(Pulpy Kidney)
This
is caused by the organism Clostridium Welchii and/or occasionally
Clostridium Perfringens D. Both are normal inhabitants of
the gut and only when the goat is under nutritional or other stress
— usually worms — do these organisms start to proliferate and in
so doing give off a deadly toxin.
David
Mackenzie in the first (not updated) edition of Goat Husbandry
claimed that immunization against entero was not necessary in properly
looked after goats. He knew nothing of the often terrible environmental
conditions in which goats farmed in Australia are expected to live.
But, even so, in goats whose mineral requirements are fully met,
changes in habitat or feed — often the cause of an entero attack
— make no difference to their health. In fact, many vets have told
me in recent years they consider entero to be a much over-rated
disease in goats because, on the average, goat farmers see to the
mineral requirements of their stock. Unfortunately vaccination,
two-in-one for entero and tetanus, often only confers a false sense
of security to the goat owner. A vaccinated goat can develop entero
(or tetanus) just as easily as an unvaccinated one if the conditions
are right for either disease. A goat that is dying from some other
