Abstract

Onset of estrus in gilts fed allyl-trenbolone for either 14 or 18 days was controlled effectively. The stage of the cycle at the beginning of treatment had little effect on the synchronization response. More than 97% of the treated gilts showed estrus within 3 to 8 days after the last progestagen feeding. Treatment did not affect gestation length, farrowing rate, or litter size.; Swine Day, Manhattan, KS, November 12, 1981
