The effect of genetic group was found to be nonsignificant for all the post partum utero-vaginal complications in first calvers while it was significant for metritis in all calvers. The effect of season of calving on all post partum utero-vaginal complications was found to be non-significant in both all calvers and first calvers. Period of calving had significant effect for retention of foetal membrane for both first calver and all calvers. The cows suffered with retention of foetal membrane and endometritis had significant effect on 305 day milk yield and total milk yield while metritis had significant effect on lactation length. 收起
