蛋白质消化率.docx

1、蛋白质消化率必须注意的是，原料生物利用率并不等于营养价值，利用率只是营养价值的一个评定指标。蛋白质利用率排名第一的豆粕其生长效果处于第l0位，而利用率排名第l6位的蚕蛹其等蛋白生长效果排名第1位。究其原因，蚕蛹为动物蛋白，必需氨基酸含量高、氨基酸平衡且含有较多未知生长因子。所以，虽然生物利用率是原料营养价值的重要评定指标，但氨基酸指标更为核心。上述论断为任泽林所下。对于此句话可以理解为，如果原料的氨基酸组成(特别是必需氨基酸)与鱼体需求不一致，即使其蛋白质消化率较高，吸收进入鱼体的蛋白质也会大量当作能量消耗或转换为脂肪等其他物质，而不能用于蛋白质的合成。注：表X A、表X B分别表示2001年
