Endoparazitózy ovcí na konvenčních farmách a biofarmách

The aim of this thesis is to assess the difference in prevalence of endoparasites in sheep bred on conventional farms and on organic farms. The theoretic part consists of a literary research on the basis of both domestic and foreign literature dealing with the problem of endoparasitic nematodes, tapeworms and coccidia in sheep. According to this research it is possible to identify seven perilous species of coccidia, fourteen species of intestinal nematodes, two species of lung nematodes, two species of tapeworms and two species of trematodes in the Czech Republic. The practical observations were carried out using nondestructive coprological techniques throughout the year 2016. Four species of coccidia (Eimeria bakuensis, Eimeria ovinoidalis, Eimeria parva, Eimeria crandalis), seven species of intestinal nematodes (Haemonchus concortus, Trychostrongylus spp.axei, Nematodirus spp., Cooperia curticei, Bunostomum trigonocephalum, Chaberia ovina, Oesophagostomum venulosum), one species of lung nematodes (Protostrongylus rufescens) and one species of tapeworms (Moniezia expansa) have been identified during the analysis. The prevalence of parasites and intensity of infection differed according to the type of farming, type of sheep care (incl. deworming) and also time of year. In total the organic farming has been assessed the healthier farming type. The practical outcome therefore is a recommendation for conventional farms to pay more attention to the sheep care with respect to the life cycles of the parasites
