摘　　要：用4组共32头仔猪进行了三种不同喂量的沼液饲养试验。试验结果表明,在饲料消化能为12.1MJ/kg、粗朊10％的营养水平下,按饲料量(风干重)的1.5倍加饲沼液对育肥猪有显著的增重效果(P<0.05),平均比对照净增20.6％,饲料利用率提高17％,育肥期缩短25％左右,有明显的生态效益和经济效益。A feeding experiment with 32 growing-finishing pigs was conducted to study the effects of biogas slurry added to the ration at different rates on pig's weight gain, feed imake, feed utilization, health and pork quality. The results showed that the rates oi pig's body weight gain and feed utilization were increased by 20. 6% and 17% respectively by adding the biogas slurry (air dry weight) at 1. 5 times as much as the ration, when the ration contained 10% gross protein and digestible energy value of 12. 1 MJ/ kg.
