摘要：

利用氮平衡试验和饲养试验,研究了日粮不同粗蛋白(CP)水平(16.1%,14.3%,13.3%,12.4%和11.7%)对肥育猪生产性能、氮和能量平衡的影响。饲养试验选取体重约为(51.86±3.11)kg的杜×长×大三元杂交猪80头,随机分为5组,每组4个重复。平衡试验选取体重为(62.96±2.04)kg的杜×长×大三元杂交猪5头,按5×5拉丁方设计。结果表明,粪氮、尿氮、总氮、氮吸收和氮沉积均随日粮CP水平的降低而降低(P<0.01),而消化能(DE,%)和代谢能/总能(ME/GE,%)随日粮CP水平的降低而升高(P<0.05)。日粮CP水平显著影响了猪的生产性能和血清尿素氮浓度(P<0.05)。日粮中添加赖氨酸(Lys)、蛋氨酸(Met)和苏氨酸(Thr),可使肥育猪日粮CP水平从16.1%降低到13.3%,且大幅度降低氮排泄量而不影响其生产性能。
