摘要

Meeting feedlot entry specifications is a major issue in supplying feeder steers. Animals falling outside specified weight ranges will not be accepted or incur a price penalty. The mean and variation in weaning weights combine with post weaning growth in affecting the weight distribution of the group approaching feedlot entry. We examined the effects of sire genotype on pre and post weaning growth, and of genotype and growth path, on feedlot entry weights.
