Sažetak
At our work we have analysed the organisation of calving in Charolais breed during the years from 1998 to 2001 at selected farm. Our monitoring of calving during winter season (from January to February) shows the percentage of calving was in particular years ranged from 43.2 to 71.1. The most calves were born in February. We found out (total all years) diffi cult calving (value 3) in 2 cases in April (1998 and 1999) and 1 case in February (1998) and 1 in March
(1999). Calving marked with value 2 (total of all years) we found out in January (2 cases), February (3 cases), March (4 cases) and from September to December past one case. From 18 cases of diffi cult calving what we found out, 11 calves (61.11 %) come from CHV 529 bull. In calves born by normal calving was found out average weight 34.75 kg, in ones born by calving with level 2 of diffi culty 36.36 kg, and in calves born by calving with diffi culty 3 was recorded average weight 41.5 kg. Recorded weight at 210 days of age in mostly cases was similar like in published breed standard.
