摘要
选择32日龄断奶三元杂交仔猪120头,按窝别、性别、体重相近的原则分为4组,每组3个重复。发酵豆粕设4个梯度,即Ⅰ组5%,Ⅱ组10%,Ⅲ组15%,Ⅳ组20%,配制4种断奶仔猪日粮分别饲喂4组试验猪,共进行14d试验。结果表明:随着发酵豆粕在断奶仔猪日粮中用量的增加,断奶仔猪的日增重提高(P<0.05),饲料转化率也得到改善;试验猪的腹泻率降低;经济效益提高。
One hundred and twenty crossbred （DurocxLandracexYorkshire）piglets weaned at 32 days age were allocated into 4 groups,3 pans/group,according to htter,sex and body weight.Four piglet starter diets were diet Ⅰ ,diet Ⅱ , diet Ⅲ and diet Ⅳ contained 5 %, 10 %, 15 % and 20 % fermented soybean meal （FSBM）,respectively.The trial lasted 14 days.Results showed that with increasing levels of dietary FSBM ,the average daily gain（ADG）and feed conversion rate （FCR）of weaned piglets were improved （P 〈 0.05）,while diarrhea rate was decreased.Supplementation of FSBM more than 5 % could reduce feed cost.
