| 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(P0.05);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(P0.05)。

| Abstract: | The effects of cysteamine on GH, SS and IGF-1 in the serum of Tibetan Sheep weaned lamb were studied. 40 80-day-old weaned lambs of Tibetan Sheep with the average initial weight of 16 kg（half male and half female） were randomly divided into 2 groups. 300 mg/（kg·BW） of CS was added in the concentrate of diet every two days. The trial lasted 42 days. The blood samples were collected from empty stomach of sheep by jugular vein in the morning of the 0th, 7th, 14th, 21st, 28th and 35th day after medication. The content of GH, SS and IGF-1 in the plasma was determined by radioimmunoassay. The results showed that adding CS in the concentrate in the test group could increase the content of GH and IGF-1 in the serum of weaned lambs of Tibetan Sheep to different extent and there was significant difference between test group and control group（P〈0.05）. SS decreased to different extent and SS content in test group had significant difference with that in control group from the 3rd week to the 42nd day. |
