Abstract

Forty-five crossbred primiparous sows were used to determine the relationship of lactation energy intake and the occurrence of post-weaning estrus to (1) body fat (percentage), (2) lean body mass (LBM) and (3) qualitative and quantitative characteristics of adipose tissue. Sows received 8 (Lo) or 16 (Hi) Meal of metabolizable energy (ME)/d during lactation and 5.4 Meal of ME/d post-weaning.
