Abstract | This paper analyzes the factors affecting the level of milk production and reproduction in terms of body condition scores (BCS) after calving and length of calving interval of 291 second-parity Holstein cows. Cows were divided by the BCS at calving into the three groups (> 3.25 b. -1; 3 b.- 2; 400 days -1); 3.25 b. and 3 b achieved better results in reproduction than cows with BCS (difference in calving interval was 25.5 days). |
