Diethylstilbestrol has become a rather common additive in beef cattle rations but has not been effective as a growth promotant in swine rations. Recent research has shown that combining the female hormone diethylstilbestrol (DES) with the male hormone methyltestosterone (MT) improves feed efficiency of pigs fed these rations from a weight of about 120 lb. to market. This experiment was conducted to obtain information on the effect of these hormones on growth, feed efficiency and carcass characteristics of finishing swine.
