摘　　要：[目的]探讨断奶仔猪日粮中双低菜籽粕的适宜添加量。[方法]选取长白(♂)与八眉猪(♀)杂交一代母猪与长白(♂)杂交所产三元杂交仔猪48头,随机分为4组,12头/组,预饲期5 d,然后进行28 d饲喂试验。第1、第2和第3组饲粮中双低菜籽粕的添加量分别为5%,7%和9%,第4组为对照组,不添加双低菜籽粕,平衡日粮中的消化能。[结果]Ⅱ组断奶仔猪平均日增重最高;第7天与Ⅲ组,第14天和第21天与Ⅲ、Ⅳ组,第28天与其他3组均差异显著(P<0.05)。[结论]双低菜籽粕含量为7%时增重效果最好。[Objective]To investigate the appropriate amount of double-low rapeseed meal in the diet of piglets.[Method]A total of 48 Tri-breed crossbred piglets,which were given birth by Landrace（♂） and Bamei（♀） hybrid generation sows hybridizing with Changbai（♂） hybrid produced,were randomly divided into 4 groups,12 piglets in each group.Pre-feeding period was 5 d and the feeding experiment period was 28 d.The piglets in Group 1,Group 2 and Group 3 were fed with diet adding 5%,7% and 9% double-low rapeseed meal,respectively.Group 4 were fed with diet adding no double-low rapeseed meal.All the digestible energy of diets was balanced.[Result] The ADG of Group 2 was highest,and was significantly different（P0.05） with that of Group 3 at 7,14,21 and 28 d,Group 4 at 14,21 and 28 d,Group 1 at 28 d.[Conculsion]7% Double-low rapeseed meal is the best for weight gain.
