The aim of this thesis was the evaluation of the meat performance of Salers beef-cattle bred in two private farms under different climatic conditions (altitude) one farm was situated 450 m above sea level, the other 750850 m above sea level. The evaluation included 36 purebred breeding-cows and 87 calves in the first farm and 38 purebred breeding-cows and 64 calves in the second farm. The observation was carried out in the period 20142016. The average age of the cows bred in the lower altitude farm was 8.5 years, 6.3 years in the second farm. The average calving interval of cows in the first farm was 392.10 days, calving interval of cows from the mountain area farm was 492.60 days. The first calving of cows was reached in three years on both farms (2.8 and 2.9 years respectively). The calves born on the farm in the higher altitude had higher birth weight and daily gains to the age of 210 days. The difference of the average birth weight between the groups was 5.7 kg, 10.94 kg at the age of 120 days, and 25.63 kg at the age of 210 days. When comparing live weight, the calves from natural breeding had better results than the calves from artificial insemination. The study proved an excellent milking capacity of Salers cows and therefore a good growth ability of the calves even under mountain condition of Šumava.
