Abstract:Two trials were performed at the Corozal Substation with Holstein heifers subjected to one of five feeding regimes to determine possible effects of feeding practices on development of heifers bred to calve at 28 to 29 months with minimum body weight of 472.5 kg. Pasture supplemented with a bulky feed at either 1.80, 1.35, or 1.35 to 2.70 kg/head/day when pastures were poor did not result in a significant difference in net gains of the animals at 24 mo of age, age at calving, or services per conception when com… Show more
