PECULIARITIES OF REGIONAL EPIZOOTOLOGY OF DREPANIDOTAENIOSIS OF KUBAN GEESE IN THE KABARDINO-BALKAR REPUBLIC

Abstract

The article is devoted to the study of regional epizootology of drepanidotaeniosis of geese of different age groups in the Kabardino-Balkar Republic (the KBR). The distribution of drepanidotaeniosis in Kuban geese was studied in 2017–2021 on the basis of complete helminthological dissections of the small intestine of 300 slaughtered geese of different age groups. It was found that drepanidotaeniosis of geese has a mosaic distribution with the coverage of the most part of outdoor young birds at the age of 2 weeks to 4 months. In the study of the Kuban geese, it was found that the prevalence of invasion (IP) was characterized by high and moderate values. The average IP of drepanidotaeniosis in the geese was 17.33±1.25%. In the Kuban geese in the context of natural and climatic zones of the KBR, drepanidotaeniosis manifests itself with threatening values of invasion intensity (II). Drepanidotaeniosis in the plain zone was found with the II of 1–3 specimens/bird; in the foothill zone, 2–5 specimens/bird; and in the mountainous zone, 1–2 specimens/bird (average 2.33±0.28 specimens/bird). Indicators of the IP and II of drepanidotaeniosis in the Kuban geese in the KBR tended to increase in goslings aged 20 to 120 days. The opposite was observed in subsequent age groups.
