| 摘要: |
| 采用Sibbald强饲法，通过无氮饲粮法和回归法估测肉鸡内源氨基酸的损失量。结果发现，每kg干物质采食量中，2种方法估测的粗蛋白质内源损失量分别为178 414.43和142 438.89 mg，总氨基酸内源损失量分别为15 727.96和14 414.52 mg。说明无氮饲粮法和回归法均可估测内源损失量，且2种方法的估测值相似。 |

| Abstract: |
| Endogenous amino acid losses were estimated by NFD and REG after animals were force-fed according to the way of Sibbald (1976).The losses of crude protein were 178 414.43 and 142 438.89 mg/kg DMI,respectively.The losses of total amino acid were 15 727.96 and 14 414.52 mg/kg DMI,respectively.The results showed that NFD and REG could be used to estimate endogenous amino acid losses with the same accuracy (P>0.05). |
