| 摘要: |
| 通过分析北京红鸡的胴体、羽毛、鸡蛋的氨基酸组成，估计出其维持的氨基酸组成；并采用数学模型方法对不同组份进行加权，在可消化氨基酸的基础上建立了几个不同的氮基酸理想比例模式。经过与NRC模式比较，对北京红鸡理想蛋白模式进行了初步探索。假定模式中赖氨酸为100，则主要的必需氨基酸比例模式为：蛋：胱：色：苏：异亮：亮：赖=32：23：14：53：100：59：93：100。 |

| Abstract: |
| Based on the experiment of determining Beijing Brown breeding layers from 21 to 45 weeks of age and as an initial approach, by combining data of amino acid content in carcass, eggs and that of amino acid requirement for maintenance suggested by different researchers, several ideal protein patterns were obtained and compared with NRC modelProvided the lysine is 100, the optimum pattern of some main indispensable amino acids was as follow: Met:Cys:Try:Thr:Arg:Ileu:Leu:Lys=33: 23: 14: 53: 100: 59: 93: 100. |
