Abstract.Dairyandbeefcattlesectorsare at the forefrontoflivestockindustry. Among the factors hindering the intensive development of livestock industry are infectious diseases, such as trichuriasis. One of the criteria of pathogenic effect of parasites on animals are changes in the blood nourishing the parasite infected organs and tissues and being the most significant indicator of its status as a whole.Thepurposeofresearchwas thus todeterminetheimpactof trichuriasisinfectiononhematologicalindicesofyoungcattle. The studies were conducted in summer and autumn of 2015, in scientific laboratory of the Department of Parasitology and Veterinary Expertise Faculty of Veterinary Medicine of Poltava State Agrarian Academy and at the breeding factory SPP «RVD-Agro» of Cherkassy district. Experiments were performed on heifers 6-12 monthsold, ofredandwhite, andblackandwhite, andHolsteinbreedsofwhichexperimental (sick with trichuriasis) andcontrol (clinicallyhealthy) groups were formed. The results of the studies found that Trichurus parasites in the organisms of young cattle in case of lighter infestation cause anemia. This is confirmed by indices of hemoglobin content, erythrocyte number, average concentration and content of hemoglobin in erythrocyte and hematocrit values. Prospectsforfurtherresearcharetodeterminethebiochemicalparametersof bloodserum incattlein case of trichuriasisinfection
