Hodnocení ekologických a konvenčních systémů chovu masného skotu
NEDOROST, Václav
The ability of cattle to produce meat is primarily determined by the genetic foundation related to the useful type and breed affiliation. Housing technology, environment or nutrition can significantly affect the overall meat production in a given farm. Furthermore, there are often differences in the conventional and ecological method of farming within the evaluation of meat productivity. This study deals with the comparison of both farms, where the data from the performance control for the monitored period 2021 - 2023 are used to compare the results. In both farms, the Aberdeen Angus breed was evaluated, where the birth weight of calves, body weight at the age of 210 days and average daily gain of animals.

Endoparazitózy ovcí na konvenčních farmách a biofarmách
Vomáčková, Karolína
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.

Etologie prasat v konvenčním a alternativním chovu
Střelcová, Anna
The thesis deals with the domesticated pig. It involves it's history, ethological needs, expressions of intelligence and pathological phenomena when the animal's needs are not met. Furthermore, the thesis deals with the two basic methods of breeding of this farm animal, i.e. conventional breeding and ecological breeding. In order for the animal expressions in different methods of breeding to be compared, ethological observations were conducted and recorded in conventional breeding, ecological breeding and also in free-range breeding, where the conditions are most similar to those of wild boars. The observations are then compared and it is established, how well were the ethological needs of pigs met in each of the variety of breeding methods.
