Summary
Two trials were conducted to evaluate limit-feeding of finishing diets to yearling steers in different seasonal environments. In Trial 1, 72 yearling steers were fed (I) ad libitum or (2) 93% of ad libitum (restricted) from July through early November. Trial 2 was conducted from January through early May with a similar group of steers. Weather data collected at the feedlot indicated that the weather during Trial 1 was similar to the 30-year average (Trial 1 average air temperature = 62 OF), but the weather during Trial 2 was 10°F warmer than typical (average air temperature = 37 OF). In both trials, dry matter intakes were lower for restricted than controls as intended (P<.001), but average daily gains did not differ (P>.10). This resulted in numerically improved feed/gain but only approached significance in Trial 1 (P=.14). Carcass characteristics were not affected by treatment (P >.10) with the exception of dressing percent in Trial 1, but this difference was not found in Trial 2. Limit-feeding of finishing rations to yearling steers tended to improve feed/gain in warm summer as well as moderate winter-spring environments.
