A.S. Series 71-22
Results of numerous experiments have shown that diethylstilbestrol at 10 mg. daily in the feed of implanted at 30 to 36 mg. improves weight gains and feed efficiency of feedlot cattle. More recently it has been reported that feeding more than 10 mg. daily to heavier cattle results in further stimulation of weight gains and feed efficiency. Feeding of 20 mg. per head daily of diethylstilbestrol is now cleared for feedlot cattle above 750 lb.
