In manuscript generalized results of own investigations and received materials on distribution and structure of parasitocenoses of cattle in the conditions of farms of the Central region of Ukraine. For the first time in Ukraine, a meta-analysis of the prevalence of fascioliasis, dicrocoeliasis, paramphistomiasis and gastrointestinal strongilates in cattle and small ruminants in the world was conducted. The conducted histological examination of the liver and hepatic lymph nodes revealed that the toxic effect of Fasciolа on the body leads to inflammatory and hyperplastic reactions in organs with the phenomena of hyperplasia of lymphoid tissue and the destruction of lymph nodes, edema and fibrosis of the stroma. During the four months of lactation, the productivity of cows treated with trematozol was 13.7 % higher than that of cows in the control group. At Fasciola, Dicrocoelium and gastrointestinal strongyloidiasis parasitizing, the extenseffectiveness and intenseeffectiveness of kombitrem are 100 %. Raphenzol and trematozol in polyinfection, one of the components of which is Paramphistomum, exhibit 100 % of efficacies. For two months of lactation, the productivity of cows treated with kombitrem by 17.6 % and with raphenzol by 20.6 % higher, as compared with control group cowsproductivity.The introduction of refectin, kombitrem, and rafenzol for cattle in recommended doses does not affect negatively on the body of sick animals. In production conditions, at parasitocenoses – the highest effectiveness was revealed with the using of antihelmintics of own production: kombitrem, raphenzol, trematozol and closiveron. The most effective medicines of foreign production for helminthiasis of the gastrointestinal tract are rephectin and tectin-super.
