Effects of supplementing corn silage with MGA and feeding varying levels of sorghum grain to feed-lot heifers

Authors

Abstract

Melengestrol acetate (MGA) 1S a new drug recently approved for use in the supplement portion of rations of feed-lot heifers. The recommended level is from 0.25 to 0.50 mg. per head per day. A 48-hour withdrawal period is required before slaughter. Several experiment stations have shown improved rate of gain, feed utilization and suppressed estrus in feed-lot heifers on high concentrate rations plus MGA.
