【 摘 要 】

Objective of research:  to study dynamics of formation of parasitocenoses in cattle on a stabled and pastured management regime in the Chechen Republic.Materials and methods: The research was conducted in 2014–2015 at the state factory farm «Terek» in Shelkovsky region of the Chechen Republic.Fecal samples from 67 calves from the birth to one year were taken monthly and investigated by flotation and Baermann techniques to reveal eggs/larvae of helminths and protozoan cysts.Animals occasionally culled for economic reasons were killed in slaughterhouses and underwent a helminthological autopsy to detect imaginal forms of helminths. Altogether 155 heads of cattle were dissected and investigated. The species belonging of helminths was determined according to the «Determinant of cattle helminths» by V. M. Ivashkin, S. A. Muhamadiev (1981).Results and discussion: The parasite system of cattle is presented by 29 species of helminths and 2 species of protozoa. Strongyloides papillosus, Neoascaris vitulorum, Cryptosporidium parva и Eimeria spp.  parasitise calves of 1-3 months of age which are on a stabled regime.Moniezia autumnalia, M. benedeni, N. vitulorum, Dictyocaulus viviparus, Bunostomum phlebotomum, S. papillosus (by different intensity of invasion) were detected in calves 4-5 months of age grazing on pasture.  The species composition and intensity of invasion will increase with an increase in the age of animals.
