A long-term study at the University of Nebraska’s Gudmundsen Sandhills Laboratory located near Whitman, Neb., found calf birth weight, weaning weight and adjusted 205-day weight were not statistically different between progeny from cows that were identified with bad udders and cows that were identified as having good udders, reports onpasture.com.
Steer calves from cows with bad udders and cows with good udders had similar feedlot entry body weight, final feedlot body weight, dry matter intake, average daily gain and feed to gain ratio. However, there was a difference in carcass performance.
Steers that nursed cows with good udders had greater hot carcass weights and backfat at harvest than their counterparts from cows with bad udders. Although feedlot entry weight and final weight were similar, they were numerically greater for steers coming from cows with good udders, which may have increased hot carcass weights at harvest.
