The influence of selenium and Systamex was examined on 40 sheep 7-month old, naturally infected by gastrointestinal nematodes. The periods of development and pregnancy were taken into account. In group I Vita-E-selen was applied at a dose of 1 ml/kg b/w, in group II Systamex at a dose of 7.5 mg/kg b/w was applied and in group III both preparates were used. Group IV was untreated and served as a control. The preparates were applied to sheep at puberty, before covering in the first week of pregnancy, a week before lambing and one week after weaning of lambs. Intensiveness and extensiveness of parasitic invasion in control animals was minimal at puberty (47%), significantly higher during covering and pregnancy (77% and 80%, respectively), the lowest during lambing, lactation and drying period. In the experimental groups mainly in group II and III significantly lowered intensiveness and extensiveness of invasion by gastro-intestinal nematodes were observed. An especially low number of parasitic eggs was found in the feces of sheep during puberty (300-900 eggs/g), while a higher one during other periods of physiological development of sheep. The highest number of eggs per 1 g of feces was noted during pregnancy after the application of selenium (66 000/g). Selenium did not significantly affect the intensiveness and extensiveness of invasion. However, selenium used together with Systamex largely reduced the invasion of gastro-intestinal nematodes in sheep and improved the condition of animals.
