Analýza stáda plemene Highland chovaného v horských podmínkách
 HÁLOVÁ, Ludmila
Main aim of the diploma thesis was the analysis of Highland cattle herd and presentation of possibilities of this breed usage in mountain and submoutain areas in the area of the Czech Republic with respect to production of breeding stock and beef. Secondary target was to evaluate the longevity and length of productive life phase of cows of this breed and to describe all management procedures of the studied herd. On the ecological farm with extensive breeding of Highland cattle where the research was done total number of 60 cows and 101 calfs was bred. The structure of cows was analysed according to the year of birth, number of calves, calving interval, age at the first calving and birth difficulty. The average age of cows in the herd was 5 years and maximum number of calves per cow was 11. Calving interval was up to 350 days in 20.4% of the breeding cows, however 14.8% of cows experienced calving interval even more than 710 days. The age at the time of first calving was up to 4 years and the birth difficulty was classified as 100% without any human help. The calves reached in the years 2014 and 2015 an average weight at the age of 120 days 120 kg and 129 kg respectively. At the age of 210 days the weights were 177 kg and 182 kg respectively. The average daily gains were 825 g and 735 g in case of 120 days and 884 g and 772 g in case of 210 days respectively. The difference was not statistically significant. The average weight of steers at the age of 20 months was approx. 335 kg and slaughter weight at 46 months was 563 kg in average. It can be claimed that with appropriate herd management comparable results can be reached under average conditions in the Czech Republic. This also means that a satisfying economic profit is attainable
