Two groups of 40 S A Mutton merino ewes were used to determine the effect of body mass and condition score on the response of immunisation against androstenedione. The effect of immunisation was significant (P less than 0.05) on ovulation rate (1.64 for non-immunised and 2.08 for immunised ewes) and higher body mass and condition scores acted complimentary to the effect of immunisation. The ovulation rate in control ewes was more closely related to condition score (r = 0.511) and body mass (r = 0.600) at the end of the experimental period than in the immunised ewe group (r = 0.302 and 0.235).
选用两组各40只南澳大利亚美利奴母羊，以确定体重和体况评分对免疫雄烯二酮反应的影响。免疫对排卵率有显著影响（P小于0.05）（未免疫母羊排卵率为1.64，免疫母羊为2.08），较高的体重和体况评分对免疫效果起补充作用。与免疫母羊组（r = 0.302和0.235）相比，实验期末对照母羊的排卵率与体况评分（r = 0.511）和体重（r = 0.600）的相关性更强。
