Correlation analysis of production and reproduction traits in twinn living under identical and different conditions

Popis výsledku v původním jazyce

The study was focused on the correlation of production and reproduction traits in holstein twinn living under identical and different conditions. Only cows with complete pedigree were included into the research (H100). Evaluated traits in the field of reproduction were service period (period between first calving till getting pregnant;), calving interval (period between first and second calving) and age at first calving. Production traits included milk yield at 1st lactation (kg of milk, % of fat, % ofprotein, kg of fat and kg of protein). The number of studid twin living on identical farms was 830 pairs. The number of studid twin living on different farms was 104 pairs. In sibling pairs, living under different conditions, was found in all productionand reproduction traits higher differences. These differences were not statistically significantly higher than in full sibling pairs living under identical conditions. It was found also higher variability in siblings living under differen
