ABSTRACT This study evaluated the effects of maternal protein-energy supplementation during gestation on performance, reproductive traits, and carcass characteristics of Nellore bulls during the finishing phase. Twenty-eight bulls sired by the same bull and born to nulliparous dams were used. From pregnancy confirmation at 60 d of gestation until calving, dams received either mineral supplementation (non-programmed group, 0.3 g kg−1 body weight day−1) or protein-energy supplementation (fetal programming group, 5.0 g kg−1 body weight day−1). After birth, all calves were […]
