Faktory ovlivňující zabřezávání a trvání gravidity u skotu

The bachelor's thesis is focused on the analysis of the factors affecting the length of pregnancy and calving interval in the herd of the Czech spotted cattle. The study was performed on 800 animals. The length of pregnancy was affected by the interactions between the month of birth and parity. The length of calving interval was influenced by the number of insemination. These factors need special attention, because good reproduction in the herd is necessary to ensure the high milk yield in dairy cattle
