Abstract

Detrimental effects of twinning have been reported in dairy herds. Dystocia, premature calving, retained placenta, abortion and delivery of freemartins, and their subsequent effects on reproductive indices and milk production, have been studied extensively. In the present report, negative effects and losses of twinning on reproductive indices, postpartum conditions and milk production were studied retrospectively in a large dairy herd.
