EPIZOOTOLOGICALLY SIGNIFICANT HELMINTH INFECTIONS IN GOATS IN THE PLAIN BELT OF DAGESTAN

Abstract

The paper presents the results of the studies on the main helminth infections of goats performed in the plain belt of Dagestan. Materials on this issue are published for the first time. In 2000–2020, 120 goats of different ages were examined during their lifetime and post mortem according to seasons of the year. The study was performed by methods of complete helminthological dissection per K. I. Skrjabin and a flotation method with a saturated ammonium nitrate solution according to G. A. Kotelnikov, V. M. Khrenov and Berman-Orlov. Goats in the plain belt were infected with 33 helminth species with the prevalence of infection (IP) of 1.0– 60.0% and the infection intensity (II) of 1–2360 specimens. Epizootologically significant were fascioliasis, dicroceliasis, monieziasis, echinococcosis, chabertiosis, bunostomiasis, trichostrongylosis, haemonchosis, nematodirosis, dictyocaulosis and protostrongylidosis. The goats were infected by causative agents of these helminths with the IP of 15.6–60.0% and the II of 25–2360 specimens. Goats catch the above helminth infections annually showing mixed infections where the number of pathogens varies from 5 to 14 species. Goats in lowland Dagestan were infected with 33 helminth species. Epizootologically significant were fascioliasis, dicroceliasis, monieziasis, echinococcosis, chabertiosis, bunostomiasis, trichostrongylosis, haemonchosis, nematodirosis and dictyocaulosis. Helminthiasis was recorded in mixed infections where the number of pathogens varies from 5 to 14 species.
