Abstract
The article presents information about sheep sarcocystosis, which in recent
years has become quite widespread in many countries of the world and in certain
regions of the Russian Federation. The results of veterinary and sanitary examination
at 32 animal processing enterprises for the last 27 months have been analyzed.
It was established that sarcocystosis is detected in 1,04...1,17% of sheep arriving
for slaughter.
The extent of infection of sheep with sarcocystosis depends on the age of the
animals. The disease is more often found in adult sheep and much less often in
young animals. More often adult sheep are ill and less young ones. Sarcocysts were not detected in lambs aged 4...4,5 months, in young animals older than 5...6
months, the pathogen is found in isolated cases, and only when sheep over a year
are slaughtered, sarcocysts can be found in 1,02% of the livestock. In ewes and
rams, the extent of sarcocystosis increased irregularly, and in some batches of
sheep received at slaughterhouses, sarcocystosis of weak (72,5%) degree was more
often noted, less often – of moderate (14,6%) and strong (3,2%) degree.
