Abortions in Sheep - the Silent Killer
It is considered normal for one and a half to two percent of ewes to abort each year with any more than five percent being classified as an abortion storm and requiring investigation. While abortion outbreaks in sheep are seen less frequently than in cattle, they are of significant economic consequence, reducing marking percentages and increasing the number of dry sheep. Infectious causes are most common and include Campylobacter, Toxoplasma, Listeria, Brucella sp and Salmonella sp.
