| 摘 要： | 通过Ｓｉｂｂａｌｄ（１９７６）强饲法研究肉鸡饲粮粗蛋白（ＣＰ）、氨基酸（ＡＡ）含量对其表观代谢率的影响。结果表明，随饲粮ＣＰ、ＡＡ含量的增加，表观代谢率呈显著的二次变化关系（Ｐ〈０．０５），衡量饲料ＡＡ营养价值时应严格控制测试条件或采用真代谢率指标。 |

| Abstract: | The effect of broiler dietary amino acid level on its apparent metabolizability were studied by force-feeding method.The results showed that the dietary amino acid level quadratically affected its apparent metabolizability(P<0.05),and it was necessary to control test conditions and adopt true metabolizability when the feed nutrition value were valued. |
| Keywords: | Broiler chickens Dietary amino acid Apparent metabolizahility Regression analysis |
