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.
