摘　　要：用FOSS2300瑞士全自动凯氏定氮仪和德国氨基酸分析仪测定新型豆粕的粗蛋白质为453．092g／kg，18种氨基酸含量为327．65g／kg，占粗蛋白质含量的72．31％，氨基酸的总消化率为79．31％。生长畜禽所需的10种必需氨基酸含量达163．36g／kg，占18种氨基酸总量的49．86％，以70日龄未取盲肠公鸡测定其消化率为74％～90％。以蛋鸡和肉仔鸡理想蛋白质为模型计算平衡性指数，表明新型豆粕为家禽的良好蛋白源。The crude protein （CP） and amino acid （AA） of new bean-meal were determined by FOSS2300 （made in Switzerland） and AA- analyzer self-motion made in Germany . CP content of new bean-meal was 453. 092 g/kg. The content of 18 kinds of AA（327. 65 g/kg）amounts reached 72.31 percent of CP, The overall true digestibility of AA was 79.31 percent of AA . Ten EAA content was 163.36 g/kg in new bear. meal, and it was 49.86 percent of 18 kinds of AA, True availability of ten EAA in new bean meal was 74 %- 90%. The index of amino acid balance was evaluated according to ideal prorein of layers and broilers. The results showed the new bean-meal is a good protein source for poultry feed.
