Pasture breeding make possible contact within sheep and eggs, larvar stages and intermediate host of parasites. Those induce that there are no one small ruminants without parasites. Negative influence of parasitic infection reflected througt lost of weight and decrement quantum of lactation. The study about gastrointestinal helminthes of goats at central parts of Serbia (Šumadija) was started in March 2017 and finished in October 2017. A total of 696 fecal samples originated from 87 flocks were analyzed using standard coprological techniques. A total of 65 animals we were analyzed by post-mortem examination. Determination of adult helminthes and eggs of parasites were done by keys given by Euzeby. We revealed same parasite species: Teladorsagia (Ostertagia) circumcincta, O.trifurcata, O.ostertagi, Trichostrongylus axei, T.colubriformis, T. vitrinus, Nematodirus spathiger, N. filicolis, Haemonchus contortus, Marshallagia marshalli, Skrjabinema ovis, Bunostomum trigonocephalum, Chabertia ovina, Oesophagostomum venulosum, Cooperia curticei, C.oncophora and C.punctata. Most prevalence species of nematode are Trichostrongylus and Ostertagia species. Although most of the gastro-intestinal species appear to follow this general pattern of seasonal distribution, some variations in intensively and duration of these characteristics with different worm species occurred. Thus with Trichostrongylus and Ostertagia species infection at mature goats the spring peak was more pronounced that the autumn infection. Poliparasitismus and infection were established at all examined animals. Numerous parasites were found at small intestine, followed by abomasus and at colon. The intensity of infection and polyparasitsm was monitored in relation to the age of goats. It was found that in younger animals intensity of infection was lower than that of older animals. The data on harmful before and effect of parasitic infections on the goat performance undoubtedly show that in the anthelminth conditions of rearing high performance animals it is necessary to conduct the measures of prophylactic treatment.
