Beginning her observation of animals in their natural
environment in the early 1930s, long before harsh, toxic chemicals
were used on our soils and our animals, Pat Coleby’s experience
has given her a rich understanding of the complex connections between
the soil quality, food and the health of animals. Coleby has raised
stock on her farm in Australia, and successfully cared for her own
animals while also acting as a resource on animal care for farmers
all over Australia, New Zealand and the United Kingdom. In "Natural
Goat Care" she brings us her encyclopedic knowledge of goats and
their health care needs to North America. Through the use of vitamins
and herbs, she teaches us how to prevent, and if it is too late
for prevention, then how to treat any number of ailments that afflict
the goat population. Coleby’s prescribed treatments for the following
"Top Ten" goat ailments are just an example of the depth and breadth
of her understanding of the needs and requirements of the goat world.

Pat Coleby’s
Natural Treatments
for the Top Ten Goat Ailments
Treatments
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.
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.
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, 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.
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
cause usually is stricken down by entero in the final stages. Vaccination
makes no difference to this process.
Kids
and young stock are most prone to entero because usually older goats
have developed an immunity. Therein lies a large snag. If an older
goat that has developed its own immunity — either naturally from
contact or from an earlier vaccination — is given an entero vaccination,
it may die from anaphylaxis and this will happen very fast. Do not
vaccinate all new arrivals as a matter of course, they are better
left alone if up in years and their previous history is not known.
Signs
of entero are misery and scouring which, if not attended to, rapidly
reach the stage where the animal loses the use of its back legs.
In advanced cases the scour will contain sloughed off pieces of
intestine. Unlike sheep, where entero kills fairly fast, goats always
give the farmer plenty of warning and time to take remedial action.
An
excellent initial treatment is quarter of a pint of warm cooking
oil; this always seems to be beneficial in any case of bad scouring.
Give 10 grams of vitamin C, with one gram of vitamin B12 and two
ml VAM in the same syringe, by injection. Then two teaspoons (10
grams) of ascorbic acid powder orally, followed by a large teaspoon
of each of the following: dolomite, slippery elm powder and crushed
garlic tablets. Repeat all except the oil, B12 and VAM at two hour
intervals.
I
had a vaccinated Angora buck boarding with me many years ago. When
I found him in the last stages of entero, after I’d been out for
the day, with bits of his gut in the scour and he was unable to
walk, I was wondering how I was going to explain his death to the
owner. He was very valuable and destined for the sales four days
later. I took the measures listed above and by the time I went to
bed he was back on his feet taking an interest in life once more.
I continued the vitamin C injections for the next three days, but
he was back to normal feeding by next day. He was washed and duly
presented at the sales on time.
There
is an antitoxin available for enterotoxemia; I have only used it
three times when goats under my care were dying from capeweed poisoning.
In all three cases, the does which had kidded normally before, produced
abnormal kids next time. Coincidence or not, it was enough to make
me decide not to use it again. None of the kids from other does
who were not given the antitoxin showed any abnormalities.
Foot and
Mouth Disease
This
is a notifiable disease in Australia (and many other countries).
Call the vet immediately if in doubt; most foot and mouth scares
here have turned out to be just that. There have only been two outbreaks
here as far as I know — one in Melton in the 1880s, and one in Gippsland
this century — and both cleared up very quickly. The disease appears
to like colder and wetter conditions than those found in Australia.
It
only affects cloven-hooved animals and signs are sudden lameness
and dribbling, with small vesicles around the feet, between the
toes and in and around the mouth area. It is acutely painful and
animals lose condition very fast. Foot and mouth disease is endemic
in many countries, including some of our nearer neighbors. In Europe
birds are usually blamed for its spread.
Anyone
who has lived through a foot and mouth outbreak in a country like
the United Kingdom where total eradication is the policy, and seen
whole herds of cattle slaughtered to prevent its spread, will realize
that the disease is best avoided at all costs. The organism can
live 120 days on clothing, possibly longer, so if travelling take
great care to have clothing and footwear disinfected on re-entry.
Foot and mouth disease is reputedly endemic in the islands to the
north of Australia.
Goats
seldom contract the disease, possibly because their mineral intake
gives them a degree of immunity. In Europe total eradication is
not carried out (as it will be here) so that valuable genetic material
can be saved. There are documented cases from Europe of cattle who
had free access to seaweed meal failing to catch foot and mouth
even after close contact with the disease. It is a highly contagious
disease. Dettman and Kalokerinos report that it has been cured with
megadoses of vitamin C. Thirty years ago in Holland cows on ad lib
seaweed meal did not succumb during an epidemic.
Injury
Call
a vet if possible, especially if there is badly torn flesh. All
wounds must be thoroughly disinfected straight away. Any good germicide
will do and it is important to do a thorough job as the initial
disinfecting should be the last. Years ago the vets taught me that
disinfectant of any sort inhibits healing and should not be used
more than once. Both tetanus and blackleg are the result of uncleaned
(often unnoticed) wounds. Fresh, clean cuts can be disinfected quite
easily and then stitched with an upholstery or surgical needle and
linen thread, both properly disinfected. The goats I have done showed
absolutely no discomfort, and did not appear to feel what I was
doing. If they do, try to get a vet to give a local anaesthetic.
If
a vet is unobtainable, after disinfection tidy up badly torn wounds
as best you can. Put on a packing of comfrey ointment if possible,
otherwise aloe vera — Septicide and Savlon are good proprietary
lines. If none of these are available, use a dressing thoroughly
soaked in Flints Oils and bind up the wound. If the wound is deep
and has not bled much, tetanus or blackleg will be a real possibility.
The former takes around 10 or more days to come out, the latter
three or four. If a vet is available the goat will have been given
antitoxin for both, otherwise keep the animal on an elevated oral
dose of vitamin C for the 10 day period, a dessertspoon a day (about
10 grams) would prevent either disease and any other condition that
might arise.
Once
the wound is safely bandaged give four grams of vitamin C by intramuscular
injection, as well as some form of supplementary vitamin E — about
2,000 units either by dissolved capsule or injection (intramuscular).
Continue with the oral dose as suggested above. If there is any
sign of blood poisoning, like heat around the wound or elevated
temperature, resume the injections of vitamin C until they disappear.
Mastitis
There
are several types of mastitis, all caused by different organisms,
but in a doe that is being properly fed (i.e., receiving her dolomite
and minerals in their correct levels regularly) mastitis should
not occur. Too high protein in the diet can be a causative factor,
this depresses the copper and when that happens the immune system
does not function as it should. If the protein in the food is excessive,
lower it.
If
a doe persistently becomes infected with mastitis, have her tested
for Caprine Arthritis Encephalitis. It is, sadly, the usual reason
for the inability of the immune system to do its task. She is incurable,
except in the short term, if that.
All
mastitis appears to be due to an imbalance in the health of the
udder, particularly the pH, caused by incorrect calcium/magnesium
ratios in the diet. Cows and goats that are regularly supplemented
with dolomite in their ration stay free from the disease. Many cow
dairymen as well as goat farmers have found this, as did I, from
the first time I was told about dolomite in the late sixties. For
reasons as yet unknown, low levels of these minerals place the udder
at risk for invasive bacteria. Diseases only occur when the food
is unbalanced and missing the proper nutrients.
There
is no doubt that badly adjusted milking machines can be a causative
factor, but the cowmen to whom I have suggested using dolomite used
milking machines. They said that mastitis (and acetonemia) became
a thing of the past from the time they started to feed it. As stated,
feeding a diet too high in protein can also be a causative factor
— check the section on feeding.
I
ran up against this with English commercial goat keepers. I had
forgotten how good the soils were over there and the fodder on offer
had double the protein we would get here. Extra copper added to
the ration of any goat getting mastitis made the dolomite and vitamin
C work, but on their own they did not.
The
advantage of using vitamins and minerals to cure mastitis is that
the goat does not develop drug resistance — nor is the farmer left
with a goat with a wrecked udder, as often happens when drugs are
used. When an antibiotic is used on mastitis, a new one has to be
found next time. I was told to destroy all my oldest goats with
subclinical mastitis as they were incurable, which was when I had
to find an alternative because my goats were too valuable.
I
learned about adjusting the calcium/magnesium balance originally
from Mrs. Maura Mackay who used to run a goat dairy before they
changed over to breed the famous Glenroy Angoras. I used dolomite
alone to cure many stubborn cases of mastitis in the early days
as some of the goats I originally bought had advanced staph mastitis.
I was informed by the sellers that lumps in the udder were hereditary.
When I first learned to use vitamin C as well as the dolomite, I
found that the cure worked considerably faster.
Long
standing cases where the udder is a total wreck are usually beyond
anyone’s powers, particularly with organisms like Klebsiella, which
have usually moved in by that stage.
One
doe I bought, who had not been milkable for three years because
of staph mastitis, became a useful member of the herd after four
weeks of treatment. She was given a dessertspoon of dolomite and
vitamin C powder daily, as well as the routine dolomite and other
minerals in her feed. I also gave her a course of five grams of
vitamin C by injection for the first three days.
The
alert farmer may nip mastitis in the bud by being observant at milking
time — a doe who kicks and makes an unusual fuss at milking should
be carefully checked.
Kinds
of Mastitis
Black
mastitis, Streptococcus, staphylococcus, myco- plasma agalactia,
klebsiella, and possibly CAE as a predisposing factor in some cases,
are some of the organisms that can invade an unhealthy udder
and cause mastitis.
Black
Mastitis
This
is the term for a very sudden and severe attack of mastitis. In
a matter of an hour or two the whole udder will become contused
and, unless immediate action is taken, it will be wrecked and the
goat will die. In such a case the doe may be alright at morning
milking and be in extremis five or less hours later, often
following a wound. The udder is hot, hard and inflamed and the goat
is obviously very ill with a high temperature. In severe cases that
are not treated immediately, the udder will turn a greenish color
and slough off (if the doe lives long enough).
Quick
action is essential. Five grams of intravenous vitamin C first,
if possible; if not, give intramuscularly with a heaped teaspoon
of dolomite and the same of vitamin C orally. My cattle dairy farmers
are using six percent pharmaceutical grade hydrogen peroxide for
this complaint and one of them told me he cured a cow with black
mastitis the same day. A goat would need three ml of hydrogen peroxide
straight into the teat orifice, break it down 50 percent with rainwater.
If this works as well as it did with the cattle it will be
a breakthrough because one has to be very quick to cure this complaint.
Repeat the entire regimen described above in one hour, then every
three hours for the first day and again the second day if no improvement
is seen. Otherwise continue to give the oral dose night and morning,
with five cc of vitamin C by injection daily until the udder starts
to look and feel normal. Cease the injections, but continue with
the oral dose of vitamin C and dolomite daily until all lumps are
gone. This usually takes about ten days. During this time, milk
the udder out as gently and as much as possible. The doe will need
careful and patient handling.
Clinical
Mastitis
This
is usually due to a streptococcus infection. The milk becomes viscous,
stringy and offensive. Treatment as above will bring about a recovery.
Subclinical
Mastitis
This
is an insidious complaint usually caused by a staph infection and
is difficult to diagnose. The first sign will be that the milk,
instead of keeping the usual seven to 10 days, will "go off" by
the third or fourth day which clean, properly cooled milk from healthy
goats does not do. The test for subclinical mastitis cannot be done
with a rapid mastitis check, it has to be plated for at least 36
hours for diagnosis. If the condition is allowed to continue unchecked,
round, hard lumps will start forming in the udder and eventually
the doe will become ill and the udder useless.
A
heaped teaspoon each of dolomite and vitamin C powder night and
morning for three days, or as long as it takes for the milk to be
tested clear, will effect a cure. The lumps, if long standing, may
take a week or two of this treatment to disperse.
Mastitis
Caused by Avocado Foliage
It
is only in the last few years that farmers have realized that this
can happen to both cows and goats. Initially, the avocado reduces
the amount of milk quite materially and, if the beasts are not prevented
from grazing it, mastitis follows. Do not allow goats (or other
lactating animals) to eat avocado trees.
Procedures
In
all cases of mastitis, milk out the affected animals as usual, but
milk them after the healthy animals and take strict hygienic precautions.
The mandatory dose of "dry cow" when a goat goes dry (if she does)
is quite unnecessary if the does (fresh milkers as well) are fed
their normal amount of minerals regularly. This, of course, includes
cider vinegar fed on a regular basis; it is another great help in
complete udder health, 10 to 20 ml a day per goat.
Metritis
This
is an inflammation of the uterus and quite often the only sign is
slightly lowered health. It can occur at any time, not always just
after kidding. Sometimes a slight offensive discharge is seen, but
more often it is lowered health that alerts the farmer. Metritis
should not occur in healthy animals. In recent years it seems to
have been confined to CAE-positive does. A vet will confirm the
presence of the disease. If it occurs out of the breeding season,
the vet will possibly say the same thing that I was told when one
of my goats first contracted it: "Feed her up well and she will
get over it." I did just that and by the breeding season the swab
was clear (this has to be done when the doe is in season).
However,
a base lack of the necessary vitamins A and D is the chief cause
for all diseases of this kind. Extra vitamin A in the form of a
teaspoon of cod liver oil orally for three days, with a dessertspoon
of vitamin C orally for the same time, will usually make certain
the next swab is clear. However if the doe is very ill, five grams
of vitamin C by injection should be given daily for three days as
well, followed by a dessertspoon of the powder orally for at least
a week. Continue with the vitamin A and D for the same time. (If
does contract metritis out of the breeding season, it may well be
seven months before they can be swabbed). These uterine disturbances
often mean that the doe’s diet has been low in vitamin A — due to
drought or poor quality feed. A long dry period puts animals who
do not get their cod liver oil occasionally at risk.
Any
doe that has had metritis whether on the farm or coming for service
must have a clear swab (done when she first comes into season) before
going to the buck again.
Metritis
can make milk unsafe to drink and it must be heat treated before
being fed to a kid (goat) or human.
Milk Fever
This
is not really a fever, rather the reverse. The doe will be low in
spirits to the point of lethargy following kidding. She will have
poor muscle control, difficulty in standing at all, her pupils will
be enlarged because the eye muscles have relaxed — all very similar
to snake bite.
The
sudden drain of calcium and magnesium from the doe’s system following
kidding will mean there is not enough to sustain her. Milk fever
does not seem to occur in does who have been receiving the correct
minerals.
Quick
action is necessary or she will die, give calcium borogluconate
(with magnesium) or any proprietary milk fever preparation as per
directions on the bottle. This is easily obtained at any farm store.
The injections can be given in four doses to speed the process.
Give injections to each side of the shoulder and each side of the
rump. Hungerford states in his works that this injection must include
both calcium and magnesium.
Some
does are more prone to milk fever than others, usually (but not
invariably) the high producers. It would be wise to give them a
little extra dolomite coming up to kidding and an A, D and E injection.
Poisons
Poisonous
plants have been covered in Chapter 6. Other toxic materials are
occasionally met on the goat farm.
Arsenic
I
have nursed a goat through this form of poisoning. She was vomiting
and it is rare for a goat to do that and live. Her breath had a
strange smell and she was in a state of total collapse. I used everything
I knew, massive intramuscular injections of vitamin C (10 grams),
B12 (three ml), B1 (three cc), B15 (three ml), vitamin E (2,000
units orally). A tablespoon of vitamin C and the same of dolomite
were also given orally with slippery elm. Both of these have an
absorbent action in the case of toxins. All this was given every
hour for the first few hours until the extreme signs abated — it
took 12 hours of fighting before I realized that she would live.
A hollow victory, because further enquiry elicited the fact that
arsenic causes chromosome, bone marrow and possible renal damage
and, in spite of all efforts, the doe was never very strong again
— but one has to try.
Fireweed
(Senecio spp.)
This
is generally found in the northern parts of New South Wales and
invariably grows on very poor, played-out land. A farmer who had
top dressed his fireweed-infested farm three years ago in northern
New South Wales called to tell me it was all gone the following
year — much easier and more effective than pulling it up. He spread
the lime, gypsum and dolomite as advised on the soil analysis.
Goats
would not normally eat fireweed unless grazing was very scarce,
which it usually is if the land is poor enough for it to proliferate.
There is no sign of any malaise for about 18 months. The doe I had
kidded normally and a few months later she started to go down hill.
I was fighting with everything I knew; the vets had no clue as to
how to treat her either. Then I went up to Queensland to talk at
a goat seminar and Dr. Ross Mackenzie was one of the speakers; he
spoke on poison plants (see the excellent book he and Ralph Dowling
wrote in the bibliography) and he mentioned the poisonous action
of fireweed and its effects on animals. The description so exactly
fitted my doe that I had a talk with him saying she had come from
northern New South Wales. He told me to post-mortem her when I got
home and that I would find the liver had become, small, flat and
hard and the edges would have a scalloped appearance. He was right
and I kicked myself for having let her suffer.
Nitrate
Poisoning
The
classic sign of this sort of poisoning is a strange sweet smell
on the scour. It is quite unlike the smell of normal manure or of
a scouring goat with intestinal disturbances — and only occurs with
nitrate poisoning. Motor disturbances, such as convulsing at sudden
noises, could easily cause the condition to be mistaken for tetanus
in the first instance, as was done by the vet and myself in the
first case I had.
As
mentioned in Chapter 6, Dr. Selwyn Everist said that vitamin C was
the only remedy he could suggest, but it does not always work. An
initial injection of five to seven grams followed by a teaspoon
of ascorbic acid and dolomite powder, a drench of 10 ml of Vitec
liquid seaweed should be given immediately. I found that the poisoning
had set up a long-term fatal iodine deficiency. The deaths stopped
once I made iodine available in the form of ad lib seaweed meal.
On post-mortem the blood appears a black color due to lack of oxygen,
have it checked.
Organophosphate
Poisoning
This
poisoning is the most dreaded by any vet or doctor because there
is so little that can be done. According to Dr. Kalokerinos, vitamins
C, A, E, and zinc are the best antidotes for humans. This saved
some alpacas willfully poisoned in New Zealand some years ago. The
latter could be introduced in the form of seaweed meal in small
quantities as it contains high zinc. Give a teaspoon a day and let
the goat take more if it wants it. For one week provide daily doses
of 60,000 units of vitamin A, 20 grams orally (two tablespoons)
of vitamin C orally and 10 cc daily by injection, and 2,000 units
of vitamin E either orally in dissolved capsules or by injection.
This poisoning would be very much a case of "playing it by ear";
it will depend on good nursing and offering any feed that the animal
would take — no grain in any form — just bran, alfalfa chaff and
green stuff, depending on the rate of recovery.
Phosphorus
This
is found in some rat and vermin baits and produces a sweet smell
on the breath accompanied by a craving for water. On no account
must the goat be allowed to touch any liquid — the phosphorus needs
water to activate its lethal effects which burn the intestines away.
If it has drunk, shoot it as quickly as possible or it will die
in awful agony. Give the goat egg whites (six at a time) mixed with
a little glucose every hour by mouth and by injection provide five
cc of vitamin C and one cc of B12 every three hours. These must
be given until the animal shows signs of relief. This procedure
may have to go on around the clock for 24 to 48 hours (it took 36
hours with a dog under the instructions of a vet). The burning sensation
in the gut makes the animal stretch as though trying to cool its
abdomen. Once it is recovered a drink of milk and water, about two
pints all together, may be given and gradually the goat can be reintroduced
to bland feed and green stuff.
Prussic
Acid
The
antidote is a neutralizing substance such as pharmaceutical chalk
or fine dolomite. Either should be mixed with water and drenched
in — a tablespoon of powder in 200 ml of water, both work equally
well and fast. This poison is most usually found in young sugar
gum shoots and occasionally in wilted peach tree leaves.
Poison
Baits
If
the constituent is unknown (but not 1080) proceed as for arsenic
poisoning. Once the animal is stable give 10 cc of vitamin C by
injection and 1,000 units of vitamin E (consult the bottle) by injection
daily. A dessertspoon of sodium ascorbate and bland feed, such as
bran and alfalfa chaff, as well as branches and good grass — all
will aid in recovery.
Slug
Bait (Metaldehyde)
Goats
should not usually have access to slug bait. However I had a case
where a goat got into the garden and ate an ice cream container
of bait. I had chased her out and did not know she had eaten it
until after she was cured. That evening she came into milking looking
very ill indeed and, having no clue as to the cause, I gave her
10 grams of vitamin C by injection. She looked much better the next
day so I gave her half the initial quantity and then noticed that
she had a row of bumps down her spine. These came up as large boils
so I continued the 10 grams of vitamin C daily until they cleared
up and burst. She recovered fully and then I found the empty bait
container and realized what had happened. Since then no poisons
whatsoever have figured on my farm.
1080
This
poison is made up of 23 ppm sodium fluoride (fluoro-acetate). If
the antidote, which is glycerol mono-acetate, is not given within
20 minutes of ingesting the bait — shoot the goat. When carrots
are used as a baiting medium and birds pick them up and drop them,
goats taking in 1080 is real possibility.
The
animal will live for three or four hours after taking the bait and
die in terrible pain. The antidote cannot work after the initial
20 minutes. Vets do not, as a rule, carry the antidote because it
is expensive and apparently does not keep indefinitely. The vet
who investigated this for me after we tried in vain to save a neighbor’s
dog, said it was also very difficult to obtain. I am told that 1080
does not cause pain, both the vet and I would seriously query this;
the dog died in her surgery.
Fluoride
— as in reticulated water (sodium fluoride)
This
substance has an enzyme-inhibiting action. This is caused by fluoride
rendering calcium and magnesium unobtainable in the body. Without
magnesium the enzyme system cannot function according to a paper
recently printed in the Townsend Letter for Doctors from the United
States. Fortunately this does not too often affect goats, although
I have read of one herd that was quite unwell until they were taken
off fluoride treated reticulated water.
Snakebite
Snakebite
either kills instantaneously by immediate nervous paralysis or,
more usually, by slow loss of muscle control which allows time to
deal with the problem. The eye muscle is the first to relax; the
pupil appears to be spread right across the eye. People often call
me and say that their animal is ill and the eye "looks all funny
and black."
In
the section on milk fever I mentioned that the signs were almost
identical. Loss of motor control is the next step, followed by death
in bad cases, or a long illness if the bite was low in venom.
Give
15 cc of vitamin C by injection intramuscularly in the side of the
neck and repeat in two hours if necessary, although often the first
dose is enough. There is no use in looking for a vein to do an intravenous
injection because when an animal is in a state of shock, as in snakebite,
the veins collapse and cannot be found. Failing injectable vitamin
C, give a heaped teaspoon by mouth every half hour until the goat
looks better. The first time I cured a goat of snakebite was before
vitamin C injections became obtainable. The goat was bitten on the
mouth. (I did not find this out until two days later). Somehow some
of the venom must have landed in his eyes because they had clouded
over, so I gave him vitamins A and D as well as the heaped teaspoon
of vitamin C. He was staggering a little, but was quite alright
half an hour later. I repeated the dose once more. The puncture
marks, when they did show up, were on the top lip and it appeared
slightly swollen, so I squeezed out some clear colored fluid.
Keep
the patient quiet and comfortable until it is back on its feet and
eating well. The great advantage of using vitamin C — pioneered
by American Dr. Klenner in the 1930s and much used by a Californian
dog vet (Dr. Bellfield, DVM) — is that the type of snake is totally
immaterial, which is not the case if antivenin is to be used. So
often one never sees the snake anyway and vitamin C is also cheaper
and more easily available. In my experience (vets tell me I am unlucky),
anaphylactic shock to a lesser or greater degree can follow the
use of antivenin and it is almost worse than the bite. Another disadvantage
of antivenin is that if it has to be used twice in a short time,
a reaction is inevitable and could kill.
If
the location of the bite can be found — do not waste time looking
for it until after the vitamin C treatment has been implemented
— rub some sodium ascorbate powder well into it as this effectively
stops the pain which can be considerable. (I rate a red-backed spider
bite as the most painful bite I have experienced, the pain went
away within three minutes of rubbing the vitamin C well in). However,
often it is not possible, as in the case above, to see the bite
marks until the hair falls way from around them. Goats bitten on
the udder are a different story, nothing seems to help the udder.
The bite generally does not affect the rest of the animal, but in
the one case I had it totally wrecked the udder. Try large doses
of vitamin C with extra dolomite, it might work or, as in blackleg,
putting the vitamin C straight into the udder might work. I saved
the udder on another doe that had been bitten by using hydrogen
peroxide as for black mastitis. Prevention is always easier than
cure — put bells on the collars of the goats. Anyone handy at brazing
can make them from copper or brass pipe. Snakes are reputedly deaf,
but they can definitely sense the vibrations from bells. I never
had another goat bitten once I fitted them and tiger snakes were
endemic on that farm.
The
vitamin C dosage should be 2 mls to a gram, nothing less. There
have been cases of snakebite where the animals died from too low
a dose of vitamin C.
Worms
Drenches
In
Australian Goat Husbandry, written in 1978, I wrote that good husbandry
and not drenches was the long term answer to worms. Twenty years
later it is truer than ever; drench resistance — which means that
the worms mutate to cope with each drench as it is invented — is
a fact of life.
When
I was doing a talk for the local Department of Agriculture, the
convener said as he introduced me: "Well, I hope you have an answer
to worms, they are becoming resistant to drenches faster than they
can make the new ones." Quite so. Before that, when talking to a
Department of Agriculture vet who was monitoring the bloods sent
up for CAE testing, he asked me what I was up to now — a fairly
common question in the profession. I told him I had forsaken chemical
drenches and was using copper and that it was working: "Thank God
for that because soon we will need something that will work and
go on working." Again, quite so.
Natural
Resistance
As
in other species, there are hereditary lines of goats with resistance
to worms. I was fortunate to have one such line. They needed one
third the amount of drenches that the others did — before I learned
to improve my management and keep the worm problem at bay. Careful
record keeping will show up the characteristic. However we cannot
pin our faith in a number which is probably .00001 of the total
population.
Seasonal
Upsurges in Parasitic Worms
Strict
adherence to the practice and principles of organic farming are
really the only long-term defense. Nature did not intend animals
to be wiped out by worms (nor did she intend Australia to be inhabited
by our domestic stock). David Mackenzie’s statement that worms are
needed to preserve a balance in the gut at times of extra high protein
in the spring pasture was sound in the United Kingdom, Europe and
maybe New Zealand — unfortunately not here. In Australia, due to
our inherently poor soil, the herbage does not become too rich.
Farmers who do not realize that at kidding time (spring) there is
a natural upsurge of worms in the gut, will find themselves with
dead goats unless the supplements are being fed. Since I learned
to see that all goats got their copper regularly in the ration,
I have not had to give what we called the "kidding drench." The
copper in the system stops a blow-out in the worm population.
Restoring
Soil Health to Encourage Soil Fauna
If
the soil has been analyzed and remineralized and the pH is in reasonable
balance — between 5.0 and 6.5 — earth worms, dung beetles and the
soil mycorrhiza will, between them, take down and process the dung
just as fast as they can obtain it. Parasitic worms can do no harm
underground, they need damp pasture so that the larvae can crawl
up the grass and be ingested.
A
word of warning here; according to Acres U.S.A., tests running for
two years from 1988 in the United States reported that manure from
animals treated with the Ivermectin group of drugs was not processed
by soil fauna.
Good
Husbandry
Good
husbandry is the other weapon of the farmer. A goat given a choice
will not go out and graze damp grass — they are browsers by nature
and worms do not live in trees. On damp days goats must have hay
ad lib so they are not forced by hunger to graze dewy worm-infested
herbage. In the higher rainfall areas, they should have hay on demand
at all times. Overstocking is another potent cause of worm problems.
Worms
in Winter and Summer
In
areas of Europe and the United States where there is a winter freeze
up, and in the drier belts of Australia and the United States, there
is virtually a closed season for worms. They cannot operate in freezing
or extremely dry conditions. But in the more temperate parts of
the world usually chosen for goat dairying (partly due to the proximity
of markets) this does not apply — worms thrive all the year round.
Goats
are clever animals. Watch them when they go out to graze. If they
have a choice and plenty of room, they will first graze the areas
that the sun has been on longest, ensuring that the grass they graze
is dry and relatively clear of worm larvae and eggs.
Alternating
Paddocks and Giving Goats a Choice
Another
weapon against worms is to run stock that do not share the same
type of worms. With goats, horses are the only animal that is suitable.
If the horses are well mannered and handled there should be no problem,
but on no account allow the goats to be chased. Buck paddocks should
be alternated and spelled regularly and be big enough to put a horse
in when the bucks come out, so that the horse can graze them to
the ground. Then a few buckets of dolomite can be spread and the
runs left until the fresh new growth comes away. I found this a
very successful strategy for years and the bucks were hardly ever
wormed. Do not run goats with sheep or cattle if it is avoidable.
As a preference, allow a year to elapse before running goats on
sheep country. If the land has been tested and remineralized, followed
by aeration, this time can be cut considerably. I have always let
the goats have the run of the farm — I have "goat bars" on the gates.
This is a bar about three feet long with a hole at each end with
a split link and strong snap clip in it. This bar is fastened at
one end to the gate and at the other end to the fence, keeping the
gate open, but horses are prevented from pushing through. Similarly
the fences are usually made with one high "sight" (white) wire,
with two or three plain strands underneath, confining the horses
but allowing the goats to pass where they will.
Signs
of Worm Infestation
Signs
of wormy goats are runny eyes, picky appetite, lowered milk yield,
scouring, anemia with some types of worms and occasionally bottle
jaw (illustrated in the section on liver fluke). Any or all of these
signs can mean worm infestation.
Copper
and Worms
Hungerford,
in his Diseases of Livestock, avers that unexplained scouring
is nearly always caused by a copper deficiency. After two years
of experimenting with copper levels in stock, I would enlarge on
that and say that any animal receiving its correct amount of copper
will not be troubled by worms (The Albrecht Papers
confirm this.)
It
seems that no one really knows what are the correct copper requirements
of a goat. Following the publication of an article I sent to the
United Kingdom about colored goats and copper needs, some vets decided
to work out what these were. Initially they started by trying to
fix a fatal level for the mineral. They administered what they considered
to be a lethal dose to a white goat (which does not need so much
copper as a colored one) and then waited for it to die. At the time
of the letter telling me of the experiment (a few weeks after the
experiment), the goat had never looked better and flatly refused
even to be ill.
Old-fashioned
Drenches
The
two drenches most commonly in use before proprietary drenches became
the norm were copper sulfate with either nicotine sulfate or lead
arsenate — both the latter are poisonous and, luckily, unobtainable
now — so not surprisingly this mixture killed a few animals. I did
know a few people who kept their goats healthy by giving them a
plug of good quality pipe tobacco occasionally.
Apparently,
not very many people used straight copper sulfate although, in early
1960 I asked the landlords for a worm dose for an old reprobate
who passed as a goat (which they had given me), they sent down a
tablespoon of copper sulfate. I drenched her with it — not knowing
any better or worse. After the copper sulfate the goat looked better
and that was that.
Using
Copper Sulfate as a Vermifuge
Dr.
William A. Albrecht, a highly qualified and much respected soil
scientist who studied in the United States, but lectured all over
the world (including Australia), did much research with minerals
and plants and animals. His work on copper is of particular interest.
He found that the Bordeaux mixture we used so successfully on our
orchard trees (made up of lime and copper sulfate) did not actually
kill the fungus by contact as was supposed. The tree absorbed the
copper, and fungus will not stay on a plant with adequate copper
in its tissues. Similarly, he found that when animals which had
been given copper sulfate recovered from worms, the copper did not
actually kill the worms, rather the copper was absorbed by the animal
and no worms of any kind would stay in or suck blood from an animal
that has plenty of copper in its tissues. I and others had experimented
along these lines for 10 years with horses, cattle, sheep and goats,
with 100 percent success.
Initially
I tried a maintenance dose with the goats which I kept up for nine
months, but it was so high that it seemed unrealistic. At that rate
(a small teaspoon of copper sulfate per head per day), each goat
was receiving the equivalent of nearly a two pounds of copper sulfate
per year, so I cut the amount to half. After that I did occasionally
have to give extra copper. During that nine months, the goats were
mated and kidded without having to be wormed as usual. Additionally,
the first kidders did not get the almost mandatory dose of cowpox,
there were no foot problems in spite of the fact that it was an
abnormally wet winter, and they never looked better. Ninety-five
percent of them were British Alpines, the other five percent were
either Saanens or all blacks, but they all received the same dose
of copper sulfate per head daily, run through their feed. The farm
was also low in copper.
Permanent
Supplementation
A
simple stock lick recipe for fiber and meat goats consisting of
25 pounds of dolomite, 4 pounds of yellow dusting sulfur, 4 pounds
of copper sulfate and 4 pounds of seaweed meal seems to work very
well with paddock animals. The lick must be kept dry, if not, the
dolomite will neutralize the copper and the main purpose of the
lick will be lost. A shelter of some kind is probably the best course
because the type of feeder used for sheep would not be big enough
for horned goats. The only possible addition to this lick, where
the cobalt levels are very low on the analysis, would be about a
quarter of a pound of cobalt sulphate. This lick can be used as
a dairy supplement at the rate of two grams per head per day and
it would also be a good idea to have seaweed on free access as well.
For hand-fed goats I run the copper sulfate through the feed at
a rate of a full teaspoon per head per week. Dark-colored goats
may need more than this and the rate can be increased; those who
run the all blacks should make a note. If the copper is incorporated
in the water that soaks the barley (as well as the cider vinegar
and any other minerals such as cobalt or boron (borax) that are
needed), it is mixed in with the dry feed and also dampens it; so
the copper intake is as near natural as can be managed.
Drenching
If
a drench is needed — and I do not advocate it because I find it
is unnecessary even at kidding time if the normal supplementation
of copper has been ongoing — I use a teaspoon of dolomite, half
a teaspoon of copper sulfate and a teaspoon of vitamin C powder.
Put this dry straight into the mouth from a film container.
Veterinary
Reactions
See
the comments in Drenching section. Several other vets (but not all)
with whom I have discussed these worm strategies are interested
in the possibilities; they realize only too well we are somewhere
near the end of the line with chemical drenches. It is not necessary
to withhold milking after drenching with copper. With proprietary
drenches, one goat through the milking line by mistake and the whole
day’s milk has to be thrown out — it’s happened to me.
A
British Veterinary Codex lent to me for notes by Dr. Greg
Morrison (a retired veterinary surgeon) did list copper as a vermifuge
and gave amounts slightly below what we use now. But, as mentioned,
the copper was mixed with either lead arsenate or nicotine sulfate
— no wonder the drench got a bad name.
Natural
Wormers
Copper
has already been discussed at length throughout "Natural Goat Care";
but there are other herbs and plants that also have a inhibiting
action on worms. Honeysuckle and wormwood, both of which goats may
help themselves to preferably through a fence, are two such plants;
garlic is not an option where milkers are concerned, nor is it 100
percent successful. Chenopodium oil (oil of American wormwood) was
used in Europe for many years by sheep and cattle farmers and may
still be a standby. I tried to import some years ago, but the chemist
who was doing the importation was turned down as soon as he stated
why we wanted it
I feel that the last part of this chapter is not necessary, given
that the above suggestions mean healthy goats naturally. I include
this section only for reference and stress that chemical drenches
are not the best way to deal with the problem.
Chemical
Drenches
In
1990 I wrote that there were roughly 20 drenches on the market;
eight years later many of those have been superseded and many more
"cocktails" invented. The chemicals, of which there are about 15,
remain roughly the same.
A
rough rule of thumb for using drenches is not to alternate although
this was very fashionable some years ago. Vet friends agree that
it led to massive, persistant and sometimes insoluble drench resistance
problems. Use a drench, be it "white" or "gold," for at least a
year, or more if the results are satisfactory, before changing.
The final resort, when the goats are dry, is the Ivermectin group
under the strict supervision of a vet. It is very powerful and kills
everything in the system (including the goat if the wrong amount
is used) — both beneficial and otherwise — and the milk from that
lactation cannot be used again according to industry printouts when
these drenches first came out.
Personally,
I used the "white" group — the earliest drench that became available
— with satisfactory results for 20 years. But I never "strategically"
drenched, animals were only drenched when they showed unmistakable
signs of infestation. Then the formula was apparently changed and
it started to make the goats rather ill, taking three or four days
before they came back on their milk again. This was when I started
to shop around and finally had to work it out for myself.
Strategic
Drenching
Like
alternating drenches, this practice has ensured that any drench
used will become useless fairly soon. To drench an animal because
it is a certain time of year, without taking a worm count, borders
on lunacy and yet countless people have done it for years, never
thinking what trouble they were laying up for themselves.
It
is not good to drench pregnant goats and any goats who have the
copper supplied on a permanent basis do not need worming anyway.
The moment the doe kids, the act of parturition in some way (hormonal)
triggers off a massive upsurge in the worm population. Since using
copper I have not had to do a kidding drench at all.
Doing
Worm Counts
If
the cost is not too prohibitive, having a worm count done on the
goats at fairly regular intervals is a good idea. If the goats were
found to be wormy and still looked unthrifty, the farmer would have
to look to the mineral levels and the copper sulfate in the feed
could be raised to two grams daily for a while — which could be
a lot cheaper and probably safer than drenching. Purchasing a small
microscope and learning how to use it is another option. I know
several fiber and meat breeders who have done their own counts quite
successfully for years.
Types
of Worms
An
ICI printout of 1978 listed 11 types of worms commonly found in
goats. Many of them do not seem to raise problems in my experience,
so I have listed below the most usual ones that cause trouble.
Barber’s
Pole Worm (Haemonchus Contortus)
Under
a microscope this worm looks like the old-fashioned barber’s pole
— white with blood bands (its host’s) running around it. Until the
late 1960s no one seems to have been aware of this worm in the southern
states, but it has been a dangerous scourge ever since. It is a
blood sucking worm which can debilitate a quite healthy looking
adult goat with shocking speed and kill kids even faster. Action
must be taken at once if it is suspected. It is not a problem in
goats who are receiving the correct minerals in their feed or licks.
The
worm only becomes a problem with the warm weather and sometimes
due to hormonal activity at kidding. In cold weather it encapsulates
itself in the gut, doing no harm (nor is it apparently affected
by drenches at this stage). Again this does not happen in copper
fed goats. I used to have bets with myself on the first really warm
day of spring as to how many telephone calls there would be saying
that the caller’s goat had suddenly collapsed. I always told them
to drench it — and quickly.
Signs
of barber’s pole infestation are always anemia — examine the membranes
under the eye — and the extreme suddenness of the attack. Other
signs of worm infestation such as scouring and runny eyes will show
up, but acute and sudden anemia is the chief one. I was brought
a kid very late one night that was frothing at the mouth and very
ill. It was dark and I feared poison of some sort. I managed to
keep it alive half the night, but that was all. The next day I took
the body into the local Department of Agriculture. Later on that
day, the sister was brought around in the same state, but as it
was light, I had a quick look at her eyelids, realized what the
problem was and we saved her. Barber’s
pole worm — a rapid and insidious killer — the report from the Department
confirmed next day.
In
the first instance, give a worm drench and a quick acting iron tonic
(Ironcyclene is good), and at least two cc of vitamin B12 and VAM
by injection; give the B12 every hour if necessary. Injected vitamin
C will also be found to be helpful, four to five cc for a kid, double
for an older goat (intramuscularly). Once the color of the eyelids
starts to return to normal, ensure that the patient receives copper
sulfate and has access to its ad lib seaweed meal.
Another
insidious characteristic of barber’s pole worm is that, unlike most
other worms, it has a life cycle of 10 to 14 days so if there is
a parasite problem involving more than one type of worm, it will
be necessary to give the backup drench on the 10th, 14th and 21st
days to be absolutely safe.
Brown
Stomach Worm (Ostertagia sp.)
Another
bloodsucker, but this one embeds itself in the walls of the stomach
to do its task, as well as being found in the gut — it can be active
all the year round.
This
is not so sudden or dangerous as barber’s pole, but action should
be taken with goats that appear below par and anemic (check that
it is not a copper deficiency, see sections on that mineral and
iron). A characteristic of treating this worm is that sometimes
when drenching for it, the goat will appear to recover and then
relapse again the following day. Apparently the drench can only
deal with the worms out in the gut; when they are killed, the ones
in the stomach wall detach themselves and start to work. So the
signs, generally scouring, will persist and the drench must be given
two days running. A buck I leased from Western Australia in the
1970s needed four days of drenching before he was alright — he must
have had a very heavy infestation. Ostertagia has a three-week life
cycle.
Lungworm
(Muelaris cappilaris, Dirofilaria immitis)
Persistent
coughing and below par animals are the usual sign of a lungworm
infestation. Some areas are more prone to it than others. One of
the "golden" drenches is usually indicated for lungworm; it will
kill the mature and young worms. But check before using that it
is specific for both kinds of lungworm. There was much trouble some
years ago because some drenches were only formulated for Meularis,
not for Dirofilaria and drenching often did no good at all.
The
danger of lungworm infestation is that, if there are a lot of worms
in the lungs, the drench suddenly killing them gives the goat a
lung full of dead worms and these in effect cause mechanical pneumonia.
The goat dies from suffocation — it has happened a number of times.
If a very heavy infestation is suspected give a drench that is not
specific for lungworm first, some of the "white" drenches are usually
suitable, so that the worms in the intestines are killed. Apparently
this gives the ones in the lungs a chance to move on and there is
not as great a chance of damage when the correct lungworm drench
is used.
Any
goat that has been infected with lungworm often has a slight chronic
cough for life due to lung scarring. Goats are short on lung area,
so try to avoid a lungworm epidemic if possible. Lungworm are not
so usual in dry areas, but in some of the wetter places they can
be a problem. They have a three week life cycle.
Pin
or Thread Worms (Nematodes)
These
resemble human thread worms with rather similar signs. They are
quite often present without the farmer realizing that anything is
amiss. If you see a goat doing a lot of tail wagging when she is
patently not in season, have a good look — often the worms can be
seen crawling round the anus and setting up an irritation.
Piperazine
drenches are highly effective against these worms and I never found
any of the others on the market had any effect. Piperazine is not
specifically mentioned for goats, but appears to be completely safe.
The same powder that is used for poultry can be used quite successfully.
Pinworms usually come in with a load of hay, particularly pea hay
that has been harvested off old sheep pastures. The eggs are scraped
up off the ground with the hay after harvest. They are not a problem
in goats who receive their copper.
Roundworms
(Strongyle)
This
is the most common type of worm and these days it does not rate
much publicity. It has a three-week life cycle and occasionally,
with careful watching, it can be seen in the droppings. Practically
any drench will work against them.
Tapeworm
(Monezia expansa)
Goat
tapeworm is reputedly species specific and is not the same as those
carried by dogs. I was told this was so, but I have heard of transmission
that suggested a crossing of species on more that one occasion.
Very
pot-bellied kids are quite often infected with tapeworm and careful
examination of the feces will sometimes detect the typical white
segments of the worm. It is fairly rare and, if suspected (repeated
drenching for other species of worm seems to make no difference),
have the vet test a sample of manure and he will advise on a drenching
program. For years there was only one drench for these worms (Mansonil).
Kids and young goats are generally affected, adult goats appear
to develop an immunity to tapeworm, which lives in the soil on many
farms. The intermediate stage is a soil mite — avoid contaminating
pasture if possible as it causes unthrifty kids. Tapeworms dislike
copper even more than other species of worm.
Hydatid
These
are the exception to the species specific label and can be contracted
by goats in the same way that sheep (or any other animal, human
included) catches them. Dogs and humans can pick them up from rabbit
livers or meat. An area subject to hydatid, and anywhere that sheep
have been farmed, is at risk. Make sure the goats are treated for
hydatid if necessary. Consult your vet.
Summing
up
Having
rechecked this section and revived memories of many struggles with
all the types of worms mentioned, I realize how trouble free and
uncomplicated life has been since we learned to use copper sulfate.
Animals are healthier without the poison drenches and I am certainly
a lot more relaxed.
