Z. T. Baysarova
Trichocephalosis is widespread in sheep everywhere on the territory of the Russian Federation. Distribution of trichocephalosis in sheep in different zones of the Chechen Republic and age dynamics of their infection by Trichocephalus spp. is studied. Contamination of sheep by Trichocephalus spp. studied on the basis of research of feces and post mortem investigations of intestines. In the conditions of east part of Central Caucasus Mountains the wide circulation of trichocephalosis in sheep is established. Contamination of sheep made, on the average, by Trichoceph-alus ovis of 16,71 %, T. skrjabini of 6,2 % at intensity of infection respectively 42,6±5,6 and 12,3±3,4 expl./goal. Extensiveness of the infection made in a flat zone 11,5 %, foothill – 19,8 and a mountain zone – 16,7 %. Contamination of sheep with age considerably decreases. Sheep had an equal extensiveness of the infection aged about year of 23,0 %, 1–2 years 19,4, 2–4 years – 13,6 and is more senior than 4 years – 9,5 %. Maximum contamination is established in sheep at the age of 6–12 months.
