Abortion:
There are several causes that bring about an abortion:
Moldy feed
Injury
Chlamydia
Vibriosis
Toxoplasmosis
Salmonellosis
When a feed contains mold spores and fed to pregnant ewes it can infect and destroy the placenta. As for injury abortion can be caused when a ram is running with pregnant ewes and bumps them away from feed supplies. Narrow doorways where sheep tend to rush through for feed are dangerous, especially during the later stages of pregnancy when the sheep becomes large.
Dog attacks are almost always a cause for abortion among ewes that have been chased or injured.
Disease can also cause a ewe to abort. However, the good news is that there is now a combination vaccine for enzoogic abortion and vibriosis (EAE-vibrio). This vaccine can be administered 2 weeks before the ewe is bred, with a booster shot given each year 2 weeks before breeding.
Enzootic Abortion (EAE):
This type of abortion is caused by Chlamydia psittaci, and occurs during the late term of pregnancy, it can also cause still births, and weak lambs. Chlamydia psittaci should not be confused with Chlamydia that causes respiratory disease, Epididymitis in rams, pinkeye, or arthritis in sheep. However, if a flock where Chlamydia. psittaci is present, other problems such as pneumonia can arise. The good news is that there is a vaccination for this disease.
