摘　　要：为研究熟化软颗粒教槽料对仔猪断奶前后生长性能及腹泻率的影响,试验选用8窝(共计84头)15日龄仔猪,随机分为对照组和试验组,分别饲喂同配方的粉状教槽料和软颗粒教槽料,每个组4个重复,每个重复1窝猪;试验分为两个阶段,分别为断奶前10d和断奶后5d,即15~25日龄和26~30日龄,仔猪在25日龄断奶。结果表明:在15~25日龄阶段,试验组仔猪平均日增重(ADG)较对照组无明显差异,平均日采食量(ADFI)增加了40.90%;在26~30日龄阶段,试验组ADG较对照组增加了12.21%,ADFI增加了34.41%;整个试验期,试验组ADFI较对照组增加了35.12%,ADG无明显差异,试验组的腹泻率也低于对照组;在仔猪断奶前后的3d,试验组的ADG和ADFI均高于对照组。综上,软颗粒教槽料在仔猪断奶后前期可有效地提高其采食量和日增重。The purpose of this study was to investigate the effects of new soft-creep feed on growth performance and diarrhea rate of piglets before and after weaning.A total of 8 litters (84 in total) 15-day-old piglets were randomly divided into control group (fed with powdered creep feed) and experimental group (fed with soft creep feed),4 replicates in each group,1 litter per repetition.The test was divided into two stages,10 days before weaning (15 ~ 25 days of age) and 5 days after weaning (26 ~ 30 days of age),and piglets were weaned at 25 days of age.The results showed that compared with control group,the daily feed intake(ADFI) in experimental group was increased by 40.90%,but there was no significant difference in average daily gain(ADG) at 15 ~ 25 days of age.At 26 ~ 30 days of age,compared with control group,ADFI in the experimental group was increased by 34.41%,and ADG was increased by 12.21%.Compared with the control group,there was no significant difference in ADG of the experimental group during the whole experimental period,but the ADFI of the experimental group was increased by 35.12%.The diarrhea rate of the experimental group was lower than that of the control group.At the time of 3 days before and after weaning ,the piglets' ADG and ADFI of the experimental group were higher than the control group.It could be seen that the soft creep feed could increase the feed intake and daily gain of piglets in the early stage after weaning.
