摘要
１日龄粤黄鸡６２只，随机分为４组，第Ⅰ、Ⅱ、Ⅲ、Ⅳ组牛磺酸的添加量依次为：０，０．０５％，０．１５％，０．４５％，试验期９８ｄ。试验结果表明：第Ⅳ组鸡只性腺发育明显快于第Ⅰ组（对照组）；第Ⅱ、Ⅲ、Ⅳ组公鸡血浆睾酮（Ｔ）浓度高于第Ⅰ组，其中第Ⅳ组公鸡血浆Ｔ浓度极显著高于第Ⅰ组（Ｐ＜０．０１）；第Ⅱ、Ⅲ、Ⅳ组母鸡雌二醇（Ｅ２）浓度高于第Ⅰ组，其中第Ⅳ组与第Ⅰ组比较差异显著（Ｐ＜０．０５）；第Ⅳ组血浆黄体生成素（ＬＨ）浓度显著高于第Ⅰ组（Ｐ＜０．０５）。
Sixty two day-old Yuehuang broilers were randomly divided into four groups and taurine was added at doses of 0, 0.05%, 0.15% and 0.45% respectively. In the 98-day trial, the histolo￣gy and the endocrine secretion of gonads were investigated, The results showed that: the gonads in Group IV grew significantly quicker than those in Group 1, the plasma testosterone (T)concentrations of the broilers in Group Ⅱ,Ⅲ and Ⅳ were higher than those in Group Ⅰ;Compared with Group I, the plasma estradiol (E 2) concentrations of the females in Group Ⅱ,Ⅲ and Ⅳ increased significantly and the plasma luteinizing hormone(LH) content in Group Ⅳ had notable increase. It was suggested that taurine had a promotive effect on the development and the endocrine function of the gonads of Yuehuang broilers.
