CHARACTERISTICS OF THE DISTRIBUTION OF DEMODECOSIS OF SHEEP IN SUBSISTANCE FARMINGSOF KABARDINO-BALKARIA

New data were obtained when studying the distribution of sheep demodеcosis in Kabardino-Balkaria. Peculiarities of sheep epizootological were studied from April to November 2018 in household plots. Sheep demodecosis was diagnosed on the basis of epizootological, clinical data and microscopic examination of the contents of demodectic nodules or skin scrapings in which live or dead mites of Demodex ovis were found. A total amount of 210 animals were examined. The prevalence of demodecosis of sheep in Kabardino-Balkaria belongs to epizootic ectoparasites, which manifest themselves with different intensity of invasion. Sheep demodecosis manifests itself enzootic and epizootic with high extensiveness and intensity of invasion with EI – 31,91% and II – 687,67±44,10 spec./100 cm2 of the skin. In the farms of the Baksan, Zolsky and Urvansky districts, the EI of sheep demodecosis was high and amounted to, respectively, 35.71; 28.57; 31.43% with II – 778.4±47.8 spec.; 603.0±40, 4 spec.; 681.6±44, 6 spec. per 100 cm2 of skin. The contamination of sheep with demodicosis in the household farms of the Baksansky district was comparatively more than other areas, due to the long range grazing. In the household farms of Kabardino-Balkaria, sheep demodicosis manifests itself epizootically with high extensiveness and intensity of invasion with EI – 31.91% and II – 687.67±44, 10 spec./100 cm2 of the skin, which requires urgent development of effective measures to prevent invasion.
