title: [Influence of animal breeding manner on the occurence of internal parasites].
abstract: On the turn of July and August the prevalence and intensity of internal parasites of cattle, deer, and primitive Polish horses were estimated. It was determined, that all groups of animals were infected with parasites. The prevalence and intensity of infection were diversified and depended on the animal species, breed, age, and even sex. For instance, dairy cows of lowland black-and-white breed were six times stronger infected than Polish red breed, despite using the same pasture and the same cowshed. Nematodes and coccidia were present in calves using small, frequently wet, calf-runs and at heifers grazed on pasture since early spring. Their parasites were gastrointestinal nematodes and tapeworms. Mares were infected solely with strongylids, while the sucking foals--additionally with ascarid nematodes. Mares of primitive Polish horses were infected by hookworm strongylids, ascarids, and tapeworms while stallions harboured only toothed strongylids. The animals surveyed were infected chiefly with nematodes and to a considerably smaller degree with tapeworms and coccidia.
