Abstract
Forty-eight Poland China barrows were used in an experiment designed to study the influence of subcutaneous stilbestrol and progesterone-estradiol (high and low level) implants on average daily gain and carcass composition. The hormone implants had no significant effect on gain; although stilbestrol and the high level progesterone-estradiol combination (500 mg.–10 mg.) tended to reduce growth rate. The progesterone-estradiol implants decreased average backfat probe significantly. Carcasses of the control and treated barrows were similar; however, those from barrows implanted with the high level of progesterone and estradiol showed a trend toward increased leanness.
