摘　　要：试验研究双低菜籽粕在生长猪日粮中的应用效果。结果表明 ,试验前期第 2～ 4组平均日增重与对照组无显著差异(P >0 .0 5 ) ;而第 5组日增重明显降低 (P <0 .0 5 ) ;试验后期第 4、5组日增重显著低于对照组 (P <0 .0 1)。随着双低菜籽粕添加比例的提高 ,猪的采食量明显降低 ,后期更为突出 ;各试验组料重比无明显变化 ,养分消化率呈下降的趋势 ,粗纤维消化率下降尤为明显 (P <0 .0 5 )。试验各组的经济效益均好于对照组 ,其中第 3组盈利最高。由此得出 ,在生长肥育猪前期日粮添加 10 %的双低菜籽粕、后期添加 13%的双低菜籽粕时 ,猪生长正常 ,养分利用率较高 。The application effect of canola meal in diet of growing pigs was tested. The results showed that the average daily gain of pigs in groups 2～4 in earlier stage of the test had no significant difference with that of the control group (P>0.05); while the daily gain of pigs in the group 5 decreased obviously (P<0.05). The daily gain of pigs in group 4 and group 5 in later stage was lower than that of the control group (P<0.01). With the increase of adding proportion of canola, the feed intake of pigs reduced significantly, especially in the later stage; the feed conversion rate of each group had no great changes, the nutrient digestibility tended to decrease, and the crude fiber digestibility decreased markedly (P<0.05). The highest profit was obtained from the group 3. The Results showed that when 10% canola meal was added to the diet of growing-fattening pigs in the earlier stage and 13% canola meal was added in the later stage, the pigs grew normally with a higher nutrient utilization rate and better economic benefit.
