In ewes immunized against androstenedione, ovulation rate was increased (P less than 0.001) although the number of live lambs/nursing ewe (1.37), but not the sex ratio (10 females:1 male), was similar to that of controls (1.33).
在免疫了雄烯二酮的母羊中,排卵率有所提高(P<0.001),尽管每只哺乳母羊所产活羔数(1.37只)与对照组(1.33只)相似,但性别比例(10只雌性:1只雄性)与对照组并无差异。
