yearling steers, limit-feeding, environment
Ninety-six crossbred yearling steers were allotted to either ad libitum or 93% of ad libitum intake treatments in a 117-day winter finishing trial. Intake restriction began once the 93% treatment group was started on its finishing diet. Finishing diets were formulated to result in similar absolute intakes of nutrients and feed additives. Restricted treatment dry matter intake was lower than ad libitum as intended (P<.05), but average daily gain was also less, 3.71 and 3.50 Ib per day (P<.05) and resulted in similar feed/gain, 6.01 and 6.07 (P>.82). These results are in contrast to two previous trials conducted during summer and mild winter/spring conditions and suggest that cold stress may affect the response to limit-feeding of feedlot finishing diets.
