摘要
日粮中添加３ｇ／ｔ大豆黄酮，对８７只３２日龄红布罗肉鸡进行了２８天生长对比试验。结果表明：与对照组比较，实验组公肉鸡日增重提高１０．１％（Ｐ＜０．０１），胸肌重和腿肌重分别提高６．５％（Ｐ＜０．０５）和７．２％（Ｐ＜０．０５），胸肌总ＲＮＡ含量显著提高，但总ＤＮＡ含量无显著变化；血清尿酸水平也下降１４．２％（Ｐ＜０．０５）。提示大豆黄酮促进公肉鸡肌细胞肥大肌肉蛋白质沉积。同时大豆黄酮显著提高公肉鸡血清睾酮含量；但对母肉鸡日增重和雌二醇水平无显著影响。
An experiment was conducted、vith 87 Redbro broilers of 32 days of age to investigate the effect of daidzein at dosage of 3g/t in diet on chicken growth. Compared with those of control group,the average daily body weight gain of male increased by 10. 1%(P<0.01),breast muscle weight(BMW) and leg muscle weight(LMW) increased by 6.5%(P<0.05) and 7.2%(P<0.05),total RNA content of breast muscle elevated aignificantly,and without changes in DNA content,uric acid also fowerd by 14.2%(P<0.05).The results suggest that daidzein can promote the muscle protein accretion of male broilers.Serum testosterone levels of male broilers are evidently higher than those of control group,whereas no significant effect of 3g/t daidzein on avarage daily body weight gain or serum estrogen leveis was found in femals.
