Studies on the occurrence of parasitoses in the course of mixed grazing of sheep and cattle were carried out in the years 1995-1997 in a herd of cows, heifers and calves of beef breed and their crosses (28 head) and a flock of ewes, yearlings and lambs of meat type breeds (50 to 70 heads). Results demonstrated an abrupt increase in cases of infestation with gastrointestinal nematodes (GIN) and Moniezia spp. tapeworms in lambs, yearlings and ewes as early as in the first month of grazing. To suppress these infestations, dehelmintization was performed to the end of the second month of pasture and in the autumn. Ewes were treated also prior to the beginning of grazing period. The dehelmentization of cattle was performed only before and after the housing. Basing on a comparison of results obtained during the separate grazing of sheep and cattle it is possible to conclude that the mixed grazing decreases the intensity and prevalence of gastrointestinal helminthoses.
