Abstract

Trenbolone acetate (androst-4, 9(10), 11 trien-3-one, -17 acetate) (TBA) is one of the few anabolic compounds available for use in female cattle. Best (1972) demonstrated that the growth rate of pasture fed Bos taurus heifers was increased by 38% when treated with TBA. However, Heitzman et al (1977) reported that TBA caused anoestrus in dry dairy cows. The present study used Zebu crossbred heifers to examine the effect of TBA on liveweight gain and pregnancy rates.
