【摘要】 试验选取160头初始体重接近并健康的28d断奶"杜×长×大"三元杂交仔猪随机分为4个组,即对照组、试验1组、试验2组和试验3组。每组4个重复,每个重复10头仔猪。对照组仔猪饲喂玉米-豆粕型基础日粮,试验1、2、3组分别用3%、6%、9%的发酵麸皮替换普通麸皮。结果表明:试验2组、3组的末体重、平均日增重、平均采食量相比对照组均显著提高;试验组的料重比、腹泻率和死淘率下降明显,且保育仔猪的肤色毛况得到有效改善。在保育仔猪饲料中用6%发酵麸皮替代普通麸皮,可以提高仔猪的生长速度,减少腹泻率、改善仔猪肤色,在一定范围内,添加量越大效果越好。更多还原

【Abstract】 A total of 160 crossed weaned piglets(Duroc×Landrace×Large White)with close body weights and good condition were randomly divided into control group,experimental group 1,experimental group 2,and experimental group 3.There were 4 replicates in each group and 10 piglets in each replicate.The control group was fed a corn-soybean meal-based diet.As for experiment groups 1,2,and 3,3%,6%,and 9% of the bran content in the basal diet were replaced with fermented bran,respectively.The results showed that the final body weight,average daily weight gain and average feed intake of experimental group 2 and 3 were higher than that of the control group.Compared with the control group,the feed quality ratio,diarrhea and mortality of the experiment groups were decreased,while the skin color and hair condition were greatly enhanced.The use of6%fermented bran to replace ordinary bran in the weaning piglets diet could increase the growth rate of piglets,reduce the rate of diarrhea,and improve the color of piglets.Within a certain range,the effect was better with the added amount increasing.更多还原
