双低菜籽粕在断奶仔猪日粮中的适宜添加量研究

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 ( P ＜ 0.05 ) with that of Group 3 at 7,14,21 and 28 d, Group 4 at 14,21 and 28 d, Group Ⅰ at 28 d. [ Conculsion ] 7 ％ Double-low rapeseed meal is the best for weight gain.
