Abstract

Exacerbated postpartum negative energy balance (NEB) in dairy cows leads to downstream negative health events, poor reproductive performance, and production loss. Different feeding strategies during the dry period have the potential to affect peripartal energy metabolism. The objective of this study was to describe the concentration of markers of negative energy balance (non-esterified fatty acids (NEFA) and β-hydroxybutyrate (BHB)), as well as glucose and insulin in cows being fed different dry period planes of energy.
