MACHÁČEK, Martin
This bachelor thesis deals with the evaluation of the influences that affect meat production in cattle without market milk production. The aim of the thesis was to evaluate the level of selected effects on the results of the performance of the monitored cattle herd. A selection of limousine breeds were selected, namely 78 calves born between December 2012 and January 2017 for a group of 20 breeds. The influence of lambs, childbirth, year of birth, monthly survey and the influence of the mother's exterior were chosen as selected effects on the meat performance of these calves. It was found that the influence of the child was the highest weight of calves since ZLI 739, which showed the best results in all controlled dates. These calves reached 365 days of average weight of 414.5 kg. Furthermore, it was found that the average calf weight after delivery at the first opening was 37.8 kg, and in subsequent rearing the weight of the body born at an average of 1 kg increased. Most calves were born in 2016, with 22 pieces. From the maternal exterior effect, it was found that the highest average weights in the monitored period of 120, 210 and 365 days reached the calves from the mothers with the highest score of the outside, despite the fact that these calves had the lowest average birth rate.

PISKAČ, Zdeněk
This thesis deals with the evaluation of factors affecting the determination of meat production. Meat production is increasingly popular indicator in cattle, due to the increase in the number of bred suckler cows, as a result of poor economics of dairy farming. The aim was to ensure and evaluate the results of influences on the results of performance tests in selected breeding cattle. As selected influences were chosen order of calving difficulty giving birth, month of birth of the calf, breeding value of mother, father. Do assessment was included in one group of purebred females breed Blonde d'Aquitaine, watched over 7 years. Checking performance was monitored pure breed Blonde d'Aquitaine breed in the stable Skrýšov, which include farm Krasna Hora nad Vltavou. Among the most significant findings made include weight 205,13 kilogram in 120 days in calves born from cows with breeding value 121-140. Weights reached 332,43 calves from bull ZBA 723 at 210 days of age. A bull calves from ZBA 375 was weighed average weight at 365 days, 544, 43 kilograms
