Data were obtained over a 3-yr period on the pre-weaning growth rate and weaning weight of 487 Aberdeen-Angus calves, and on the feedlot performance to slaughter at 168 days post weaning and 14 carcass traits of 394 calves. Age of dam (no 2-yr-olds) was a significant source of variation only for 205-day weaning weight, although it approached significance for pre-weaning rate of gain.
