小尾寒羊是产肉性能最好的绵羊品种之一，但因抗生素的滥用，对其肉品质和安全性造成较大负面影响。大豆黄酮属绿色植物提取物添加剂，可提高畜禽的生长性能和抗氧化能力，但在小尾寒羊中应用报道较少。研究选用不同剂量（3和6 mg·kg-1）大豆黄酮饲喂小尾寒羊，检测其对小尾寒羊生长、血液激素和抗氧化水平的影响。结果表明，大豆黄酮可显著提高小尾寒羊生长性能（P<0.05）；显著提高血清T3水平（P<0.05），但对胰岛素无显著影响；可显著提高血清SOD活性，降低MDA含量（P<0.05）；对瘤胃pH无显著影响，但可显著提高瘤胃总脱氢酶、微生物蛋白含量和瘤胃微生物总RNA（P<0.05）。

The meat performance of small-tail Han sheep is very good, but because of the abuse of antibiotics, there is a great negative impact on the quality and safety of meat. Daidzein is a extracts of soy, which was a green additive of feed. Daidzein can improve the growth performance and antioxidant capacity of livestock, but few reports of application in Small-Tail Han sheep. In the study, different dosages (3, 6 mg·kg-1) of daidzein are used in feeding of Small-Tail Han sheep, for examining the impact of daidzein on the growth, blood hormone and antioxidant leves of Small-Tail Han sheep. The results showed that daidzein significantly improve the growth performance of Small-Tail Han sheep (P<0.05);significantly raise the level of serum T3 (P<0.05), but no significant effect on insulin;can improve serum SOD activity, and decreased the content of MDA (P<0.05);no significant effect on rumen Ph, but significantly improve TDHA, MPC and rumen RNA.
