| 摘 要： | 为研究酸汤添加剂对断奶仔猪生长性能以及血清生化指标的影响,试验选用断奶日龄31 d,体重(5.34±0.86)kg的健康断奶仔猪54头,随机分为6组,每组3个重复,每个重复3头猪。试验Ⅰ组为对照组,饲喂基础日粮,试验Ⅱ、Ⅲ、Ⅳ、Ⅴ组在基础日粮中分别添加0.5%、1%、1.5%、2%的酸汤,试验Ⅵ组在基础日粮中添加0.1%复合益生菌,进行为期47 d的饲养试验。饲养试验结束前5 d,每组选留3头猪进行消化试验。结果表明:与试验Ⅰ组相比,试验Ⅴ组与试验Ⅵ组的日均采食量(ADFI)分别显著提高了20.75%、27.86%(P<0.05),试验Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ组的日增重(ADG)显著提高(P<0.05),试验Ⅴ组的腹泻率降低36.78%(P<0.05);试验Ⅱ、Ⅳ、Ⅴ、Ⅵ组的粗纤维消化率分别提高14.63%、23.59%、16.62%、19.64%(P<0.05);试验Ⅴ组与试验Ⅵ组的血清总蛋白含量分别提高13.83%、16.29%(P<0.05),试验Ⅱ、Ⅳ、Ⅴ、Ⅵ组的尿素氮分别降低15.16%、16.70%、27.91%、25.05%(P<0.05),试验Ⅴ组的葡萄糖含量提高13.24%(P<0.05)。综上结果,断奶仔猪日粮中添加适量的酸汤添加剂,可与商品复合益生菌取得大致相同的抗仔猪断奶应激效果,且预防腹泻效果更好。

| Abstract: | To study the effect of sour soup additive on growth performance and serum biochemical parameters of weaned piglets,54 healthy weaned piglets with weaning age of 31 days and weight of(5.34±0.86)kg were selected and divided into 6 groups with 3 replicates per group and 3 pigs per replicate.Experiment group 1(control group)was fed basal diet,experiment groupsⅡ,Ⅲ,Ⅳ,Ⅴwere fed 0.5%,1%,1.5%,2%sour soup with the basal diet together,respectively.The experimental groupⅥadded 0.1%compound probiotics on the basis of the control group.The trial lasted for 47 days.Five days before the end of the feeding test,3 pigs were selected for digestion testing in each group.The results showed as follows:average daily feed intake of the experimental groups V andⅥwas 20.75%and 27.86%higher than that of the experimental groupⅠ,respectively(P<0.05);The average daily gain of the experimental groupsⅡ,Ⅲ,Ⅳ,ⅤandⅥwas significantly increased compared with the experimental group I(P<0.05);Diarrhea rate of the experimental groupⅤwas 36.78%lower than that of the experimental groupⅠ(P<0.05);The digestibility of crude fiber in the experimental groupsⅡ,Ⅳ,Ⅴand VI was increased by 14.63%,23.59%,16.62%and 19.64%compared with the experimental groupⅠ,respectively(P<0.05);Total serum protein of the experimental groupsⅤandⅥwas increased by 13.83%and 16.29%compared with the experimental groupⅠ,respectively(P<0.05);the serum urea nitrogen of the experimental groupsⅡ,Ⅳ,ⅤandⅥwas15.16%,16.70%,27.91%and 25.05%lower than that of the experimental groupⅠ,respectively(P<0.05);Serum glucose of the experimental groupⅤwas increased by 13.24%compared with the experimental groupⅠ(P<0.05).To sum up,adding the appropriate amount of sour soup additive to the diet of weaned piglets could achieve approximately the same anti-weaning stress effect as that of commercial probiotics,and prevent diarrhea better. |
