Abstract

Low energy balance increases the incidence of disease and contributes to poor reproductive performance. Monensin (an ionophore) increases energy precursors in the rumen. Monensin-treated cows had higher milk yield and lower serum ketone bodies, and thus better energy status, than control cows. This study aimed to validate a previously developed model for the prediction of energy balance from test-day information. Predicted energy balance was compared for cows with or without monensin supplementation.
