摘要
本试验采用二因素二次回归正交设计，探讨饲粮赖氨酸和蛋氨酸水平对９－１６周龄雉鸡生产性能和羽毛生长的影响。结果表明：饲粮中适量添加赖氨酸和蛋氨酸均可改善其生产性能。０．７５１％赖氨酸可满足雉鸡增重和羽毛需要；０．３１０％蛋氨酸可满足雉鸡增重需要，但０．４１０％蛋氨酸能使雉鸡羽毛生长更好；保证增重的最佳赖氨酸与蛋氨酸比例为０．７５１：０．３１０；保证羽毛生长的最佳比例为０．７５１：０．４１０。
A trial with 2 factor quadratic regression right cross design was conducted to study the influence of dietary, lysine (Lys) and methionine (Met) levels on performance and feather growth of ring - necked pheasants from 9 to 6 weeks old. The results showed that optimal addition of dietary Lys and Met could improve the performance of pheasants. 0.751% Lys was enough to ensure the optimal gain and feather growth. 0.310% Met was enough to ensure the optimal gain with 0.410% Met for feather growth.
