I like sheep, and I like goats, and I’m not afraid to admit
it. One of my good neighbors calls my
sheep “prairie maggots,” and that’s okay-he just hasn’t come to appreciate them
like I have. A lot of people do, though,
and more and more sheep and goats are being raised in this area. They make excellent 4-H and FFA projects, are
easy to raise on small farms, and frankly, do not pose the same physical threat
that larger cows and horses do. Young
and old alike can take part in caring for them on the homestead.
This
time of year I see many cases of young lambs and kids that are not doing
well. They appear to stop growing
compared to their contemporaries, are thin and often have wool or hair that is
disproportionately long for their body size.
For lack of a better term, I refer to them as “skanky.”
Almost
all of them are heavily parasitized, meaning their intestines are loaded with
worms or another common parasite, coccidia.
These microscopic coccidia cause a condition called coccidiosis, which
usually results in diarrhea- but not always.
I have seen many fecal samples from animals with stools that look normal,
but microscopically are packed with coccidia and worm eggs. Young lambs and
kids can be wasting away from such parasites and not have diarrhea. If you
have some animals that look like this, take their manure to your veterinarian
to be examined-the sooner the better.
The earlier these animals are treated, the greater their chance of
returning to normal growth and of not being stunted.
Some
of these “skanky” lambs and kids are also suffering from chronic
pneumonia. Depending on the amount of
damage to their lungs, these animals may or may not survive long enough to be
productive.
One
of the main causes of this “poor-doing” condition is the timing of birth. Usually, they are among the youngest of the
lambs and kids. As the lambing or
kidding season progresses and the weather warms up, the environment they are
born into becomes more and more saturated with parasites and pneumonia-causing
bacteria. These young animals are then very
susceptible to contracting these infections.
Another
factor involved is the mother of these “skanky” animals. Often, it is the younger ewes and does that
are having these later offspring, and their colostrum, the antibody-rich first
milk, is simply not as nutritious as the colostrum of older mothers. An older
mother’s colostrum tends to have more antibodies which help prevent disease in
the newborn, compared to a younger mother’s colostrum.
One way to deal with this colostrum problem is to save and freeze the colostrum from older mothers to supplement the offspring of the first-time ewes and does. Prior to use, this frozen colostrum should be thawed at room temperature or in a warm water bath. Do not microwave colostrum, as this will denature the antibody protein and render it useless.
Of course, if there is concern about diseases such as OPP, CAE, and Johne’s in your flock, then using colostrum from other ewes or does should be avoided. In this case, commercially available colostrum could be used. I don’t know how well these products work, but I do know they can.
Also,
talk to your veterinarian about implementing an effective parasite preventive
program. Intestinal worms can be treated
with various anthelmintic drugs, while coccidia can be treated and prevented
with various feed and water medications.
Work with your veterinarian to make these “skanky” lambs and
kids a thing of the past.
