We breed our does individually and therefore know
approximately when they are scheduled to kid. This is important for us because
it allows us to watch for specific problems during their pregnancy. There are
two main type of problems related to pregnancy. They are Pregnancy Toxemia
and Abortions. Pregnancy Toxemia is a problem that we have seen many times. We
have never had a problem that we know of where the does aborted however we
have talked to friend that have had abortion problems.
Pregnancy Toxemia
This is a problem in the late pregnancy, normally the last
month and especially last two weeks. It is normally related to a doe with
multiple kids. During the last two months, the kids are adding 70% of their
birthing weight. During the final weeks, there is additional nutritional
requirements for the kids as continue to increase in size and there is
less and less room for the rumen to hold the same amount of food. The goats body
will give the kids nutritional needs the priority at the expense to the
mother. She may not be able to consume enough nutrition and the body will start
converting the mothers carbohydrates stored in her tissues. This leads to the
release of keton bodies into her blood - a sign that her metabolism is faulty.
The symptoms will be a loss of appetite, not wanting to
get up or move around, sweet-smelling breath, limping and swelling of feet or
walking very tenderly. Ketosis strips can be used to identify if the doe
is ketotic Give doe propylene glycol twice a day. We
give 60cc drench in am and pm. We also create a mixture of sodium bicarbonate
with water and give 30cc drench am and pm. Help get the doe up and moving around
during the day and offering her high energy food.
Abortions
Nutritional Problems
Proper nutrition is essential for having healthy kids.
Simultaneous deficiencies of energy and protein can cause abortion of embryos
early in the pregnancy. Deficiencies of some trace minerals such as copper and
iodine can be the cause of abortions. Also, excessive selenium for an extended
period can cause abortions.
Infectious Problems
An abortion by one or more of the goats in your herd may
indicate an infectious disease that needs an overall management response. It is
likely that your vet will be required to identify the type of infection causing
the problem.
- Chlamydiosis - caused by an intracellular
organism. Abortion typically occurs in the last 2 months of pregnancy and
especially the last 2 weeks. The rest of the pregnant herd must be considered.
Non bred does can catch the infection but it will result in their becoming
immune. You should consider injecting pregnant does with tetracycline by the
intramuscular rout to try and prevent them from aborting.
- Toxoplasmosis - this is associated with a
coccidium of cats. Cats become infected by consuming uncooked meat scraps,
placentas, and small rodents. Goats become infected by eating grass, hay or
garin contaminated by cat feces.It can result in abortion, stillbirths and
weak kids. However, reducing exposure to cat may help but in may lead to an
increase in rats that carry other diseases.
- Q Fever - a bacterial disease capable of
being transmitted from animals to people caused by Coxiella burnetii, a
rickettsial organism. C. burnetii may be found in sheep, cattle, goats, cats,
dogs, some wild animals (including many wild rodents), birds, and ticks.
Animals shed the organism in their urine, feces, milk, and especially in their
birth products. Abortion or stillbirths occur in late pregnancy, but only when
the placenta has been severely damaged. Treatment is with tetracycline.
Placentas and aborted fetuses shoud be destroyed by burning.
- Brucellosis - brucella organisms infect a goats
placenta and udder, causing abortion and mastitis When goats in an endemic
herd are in a stressful environment and management is not adequate to control
nutritional and parasitic diseases, then abortion will occur in the last 2
months of pregnancy.
- Listeriosis - caused by listeria monocytogenes a
ubiquitous organism that may be found in soil, water, plant litter and
digestive tract of ruminants. Abortions occur in the last 2 months. Treatment
is usage of tetracyclines.
