Abstract. This work is devoted to the study of the spread and seasonal dynamics of eimeriosis among large and small cattle in farms of various forms of ownership located in Krasnodar city area, as well as in Dinsky, Yeisk, Anapa, Novorossiysk, Gelendzhik and Tuapse districts. Fecal samples from cattle, sheep and goats were taken to study the epizootic situation. The scientific work was carried out taking into account the age groups of the animals. The combined Darling method, including precipitation and flotation, was used to isolate the Eimeria oocysts. The intensity of invasion was calculated using a VIGIS counting chamber and an MBI microscope, and the species composition of aimeria was determined using the determinants of Vershinin I. (1996) and Krylov M. (1996). The results showed that oocysts of Eimeria bovis were identified among young cattle in the Kuban and Krasnodarskoye experimental farms. In calves 3-6 months old, the average invasion intensity was 11 copies/head, and in forage cows - 5 copies/head. In Dinsky district, oocysts of Eimeria bovis and Eimeria zuernii were detected in calves of all age groups, with a maximum invasion intensity (86 copies/head) in animals 3-6 months old. In Yeisk district, oocysts of the species E. parva, E. faurei, E. arloingi, E. intracata and E. ninaekohlyakimovae, while the prevalence of invasion in all age groups was 100%, and the maximum intensity (90 copies/head) was observed in goats aged 6-12 months. In Anapa district, the number of sheep of different age groups (21 heads) from private subsidiary farms was examined. Three age groups were identified: lambs 3-6 months old, lambs 6-12 months old, and sheep over 1 year old. The determination of the species composition according to Vershinin established the following species of aimeria: E. faurei, E. arloingi and E. ninaekohlyakimovae. Lambs aged 3-6 months had an invasion rate of 100%, and the average invasion rate was 47 copies/head. In the age group of 6-12 months, these figures were 100% and 84 copies/goal, respectively. In adult sheep, the average invasion intensity was lower - 34 copies/head at 100% invasion intensity. 40 goats aged from 3 months to 2 years were examined in Novorossiysk district. Three age groups were identified among them: goats 3-6 months old, goats 6-12 months old and goats older than 1 year. The oocysts of E. parva, E. faurei, E. arloingi, E. intracata, and E. ninaekohlyakimovae have been identified. In goats aged 3-6 months, the average invasion intensity was 31 copies/head, in goats aged 6-12 months - 7 copies/head, in adult goats - 6 copies/head with 100% invasion intensity in all groups. 45 animals (30 goats and 15 sheep) were examined in Gelendzhik district. E. faurei, E. arloingi and E. ninaekohlyakimovae were detected in sheep, and E. parva, E. faurei, E. arloingi and E. ninaekohlyakimovae were detected in goats. The average intensity of invasion in lambs of 3-6 months was 23 copies/head, in lambs of 6-12 months - 68 copies /head, in adult sheep - 14 copies/head. In goats of 3-6 months, the average intensity of invasion was 19 copies/head, in goats of 6-12 months - 62 copies/head, in adult goats - 22 copies/head. The invasion rate was 100% in all groups. 27 goats were examined in Tuapse district. The oocysts of E. parva, E. faurei, E. arloingi, and E. ninaekohlyakimovae have been identified. In goats aged 3-6 months, the average invasion intensity was 26 copies/head, in goats aged 6-12 months - 63 copies/head, in adult goats - 15 copies/head with 100% invasion intensity in all groups. The obtained data indicate a high prevalence of eimeriosis among young farm animals in Krasnodar region, which underlines the need to develop effective preventive and curative measures.
