Crossbred, spring calving cows were used in a three-year experiment to evaluate the influence of supplemental protein prepartum and grazing sub-irrigated meadow postpartum on pregnancy rates and calf feedlot performance. Feeding supplement prepartum improved body condition score pre-calving and pre-breeding and increased the percentage of live calves at weaning but did not affect pregnancy rate or steer calf feedlot performance. Grazing sub-irrigated meadow did not change pregnancy rates or feedlot performance.
