Vyhodnotenie rastovej intenzity a exteriéru oviec plemena Zwartbles, Suffolk a Charollais

The aim of the thesis was the evaluation of growth intensity of the sheep based on the regular measurement of weight parameters and the measurement of selected indi-vidual body parts of mixed breed of Zwartbles sheep kept at the farm in Mohelno and the breeds of Suffolk and Charollais sheep kept at the School agricultural enterprise Žabčice, in between the years 2013-2015. From the results of the measurements were calculated average daily gains and aver-age live weights during predetermined days. These results were evaluated at the farm in Mohelno using factors such as litter size, sex and size together with sex. At the farm in Žabčice the evaluation was based on factors of litter size, sex, breed and sex together with breed. The statistically significant differences(p-0,05) were shown for the average daily gain in a range from 30th up to 70th day and for the average live weight in the 70th day between singles (229,4 g*day-1 and 20,62kg) and triplets (180,65 g*day-1 and 17,24kg), in the favour of singles of Zwartbles breed and between breeds of Suffolk and Charollais in the favour of muscle height and fat height in 100th day of age, whereby higher results were obtained by Suffolk breed. The results of measurements of length parameters show almost in every groups the statistically significant differences, but in the Zwartbles breed there was not demon-strated any influence of litter size on pelvic measures and also there were not demon-strated any differences between Suffolk and Charollais breeds, with an exception of shin perimeter, where the difference was significant (p-0,01), whereby the higher values were reached by Suffolk breed sheep (9,48 cm) which were fallen behind by Charollais breed sheep (8,85 cm)
