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。1 224 Duroc × Landrace × Yorkshire barrows, whos average body initial weight was about 20 kg, were fed two diets individually. The N and P outputs, the pertormance 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.
