| 摘 要： | 选用1 224头体重20 kg左右、体质健康的杜×长×大三元杂交生长猪,以玉米—豆粕型为基础日粮,对照组日粮参照NRC(1998)猪营养需要标准来设计,研究了低N、低P日粮对生长猪生长性能和对环境的影响。结果表明:在不影响猪氮、磷营养需要的条件下,降低日粮中氮、磷能有效改善猪排泄物中氮、磷对环境的污染。

| Abstract: | 1 224 Duroc×Landrace×Yorkshire barrows,whose average body initial weight was about 20 kg,were fed two diets individually.The N and P outputs,the performance and digestibility of N and P of pigs and the effects on environment were studied.The results showed that there was no significantly difference between two groups in the performance,and the N and P outputs reduced,which could reduce the pollution of N and P on the environment. |
