restricted intake, linit feeding, finishing programs
A total of 192 yearling Angus steers were used in two trials to investigate the impact of restricting feed intake on feed conversion and energy utilization. In trial 1, feed intake was restricted to approximately 83% of ad libitum. Cattle were slaughtered at a constant fatness. In trial 2, intake was restricted to approximately 93 and 85% of ad Libitum. After 56 days on feed, half of the 85% cattle were allowed to consume feed ad Libitum. Cattle were slaughtered at a constant cumulative NEg intake. Average daily gain was reduced for the restricted intake cattle compared with controls. Carcass fatness was not altered by restricting feed intake. Feed conversion and calculated dietary net energy values were not improved by restricting feed intake. Use of the net energy system appears valid over several levels of feed intake.
