Abstract:
The effect of intensity of selection for parentage and individual performance of cows, according to age structure, genetic gain and average production was studied in a dairy unit per 2000 stable places. The maximum genetic gain was achieved as a result of combined selection of cow dams when 66 per cent of heifers were selected for parentage and 20 per cent of first-calvers were culled for their performance (26.5 replacements). With increase in the selection intensity, the average milk yield increased by 3-6 per cent but the genetic efficiency of cow dams selection decreased by 10-37 per cent.
