Abstract

A two year experiment evaluated the influence of supplemental protein during the last trimester of gestation and grazing sub-irrigated meadow during the postpartum interval on pregnancy rates and calf growth in a March calving production system. Supplemental protein during the last trimester did not improve subsequent pregnancy rate but resulted in increased carcass weight. Allowing cows to graze sub-irrigated meadow during the postpartum interval improved pregnancy rates but did not change steer performance in the feedlot. Feeding supplemental protein during the last trimester of gestation and allowing cows to graze sub-irrigated meadow were both economical methods of improving production.
