Abstract

Performance and carcass characteristics were evaluated when feeding two rates of monensin in feedlot adaptation diets. Monensin was supplemented at either 360 or 480 mg/head/day during the adaptation period. During the adaptation period, interim body weight was greater and dry matter intake was less for steers fed the 360 mg/head/day treatment of monensin. Subsequently, an improvement in average daily gain and feed efficiency was observed with the 360 mg/head/day treatment. However, there were no statistical differences in final performance and carcass characteristics. These results suggest it is not beneficial to feed the 480 mg/head/day rate of monensinin the adaptation period.
