摘要: 试验研究了半胱胺(CS)对藏绵羊断奶羔羊血清中生长激素(GH)、生长抑素(SS)、血清中胰岛素样生长因子(IGF-1)的影响。将40只80日龄左右且始重平均为16 kg的(公母各半)藏绵羊断奶羔羊随机分为2组,在日粮精料中添加300 mg/(kg·BW)的CS,隔日添加1次,试验期42 d。分别于开始用药后的第0、7、14、21、28、35天早晨空腹颈静脉采血样,以放射免疫法测定血浆中GH、SS、IGF-1。结果表明,试验组精料中添加CS使藏绵羊断奶羔羊血清GH、IGF-1都有不同程度的提高,且试验组与对照组相比都有显著差异(P〈0.05);SS均有不同程度的下降,试验组与对照组相比第3周开始有显著差异(P〈0.05)。
