| 摘 要： | 研究了补偿性生长条件（孵化后第1，2，3周投喂蛋白质水平为22％，20％，18％以及16％的日粮）对肉鸡胸肉、腿肉重量及肠道长度和重量的影响。在前3周的任何一周限饲低蛋白质日粮，提高腿肉20－40g，胸肉10－19g，特别是在第2，3周投喂蛋白质18％－16％的日粮时增产幅度大于第1周，并且有增加肠道的重量和长度的趋势。结果表明，早期限饲低蛋白质日粮还有增加胸肉和腿肉重量的效果，该效果在在第2，3周供给18％－16％蛋白质日粮时差异显著。

| Abstract: | A study was conducted to examine the effect of compensatory growth condition on the weight of breast and thigh meat, weight and length of intestines using broilers fed 22%, 20% , 18% and 16% protein diets at week 1, 2 or 3. The lower protein diet at any stage of week 1~3 increased 20~40 g of the thigh meat and 10~19 g of the breast meat as compared with the control diet (CP 22%). Meanwhile, the increased magnitude of the meat weight were larger in week 2 or 3 than week 1 when CP18%~CP16% diets were provided. Similarly, the CP18%~CP16% diets also had the tendency that the weight and length of intestine tract were increased. It is concluded that in the early growth, the lower protein diet could result in the increased weight of breast and thigh meats, and the difference of this effect is significant at week 2 or 3 when the dietary protein level is 18%~16%. |
