摘　　要：9只雄性梅花鹿随机分为3组,每组3只.第1组在生茸后期用抗雄性激素CAZ处理后,每周口服1次生长抑素耗竭剂CS57,共处理4次;第2组在生茸后期只接受CAZ处理,未进行CS57处理;第3组未进行任何处理,为对照组.结果:生茸后期(7月下旬～8月下旬),第1、2组血清睾酮水平均显著低于第3组;第1组血清IGF-1水平显著高于其处理前水平和第2、3组(P<0.05);第1、2组的再生茸长度和重量均显著大于第3组(P<0.01),但第1、2组间差异不显著(P>0.05).表明在生茸后期,通过增加血清睾酮水平已经受到抑制的雄性梅花鹿血液IGF-1水平未能进一步起到促进再生茸生长的作用.Nine male sika deer were divided into three groups randomly. The deer of group 1 were treated with anti - androgen CAZ in the period of later stage of velveting, then somatosatin inhibitor CS57was fed once a week （four times in all）. The group2 were treated only with CAZ and the group3 were treated with nothing as control. The results showed： the levels of testosterone of the gruopl and 2 were obviously lower than group3 during later stage of velveting （from later July to later August） ; the serum levels of IGF - 1 in the group1 was obviously higher than group2 and group3 （P 〈 0.05）. The regrowth velvet of groupl and group2 were obviously greater in length and weight （P 〈 0.01）, but the difference between groupl and group2 was little （P 〉 0.05）. The results showed that increasing the levels of IGF- 1 of male sika deer which serum testosterone was restrained didn＇ t promote the further growth of the regrowth, velvet.
