摘　　要：试验旨在研究果寡糖制剂(fructooligosaccharide,FOS)对后备母猪的生长性能、免疫功能和肠道菌群的影响。选用相同日龄的长白×大白后备母猪224头,随机分为2组(对照组、FOS组),每组8个重复,每个重复14头。对照组饲喂基础饲粮,FOS组在基础饲粮中添加0.1%的果寡糖,试验期30 d。结果表明:1FOS组的日增重显著高于对照组(P<0.05),料重比低于对照组,饲粮蛋白质和能量的消化率高于对照组。2FOS组血清中的三碘甲状腺原氨酸(T3)、四碘甲状腺原氨酸(T4)水平显著高于对照组(P<0.05)。3FOS组血清中的免疫球蛋白G(Ig G)、免疫球蛋白M(Ig M)的水平显著高于对照组(P<0.05)。4FOS组粪便中的大肠杆菌数量显著低于对照组(P<0.05),双歧杆菌数量有所提高(P<0.05)。由此可见:FOS可以不同程度地提高后备母猪的生长性能、免疫机能,改善肠道菌群。This experiment was conducted to investigate the effects of fructooligosaccharide（FOS） ongrowth performance, immunity and intestinal flora of replacement gilts. 224 replacement gilts were ran-domly divided into 2 groups（control group, FOS group）, with 8 replications per group and 14 gilts ineach replication. Control group was fed basal diet, FOS group was fed basal diet supplemented with0.1% FOS. The experiment lasted for 30 days. The results showed that： 1 Compared with control group,average daily gain（ADG） of FOS group was significantly higher than control group（P〈0.05）, F/G was low-er than control group and apparent digestibility was higher than control group; 2 The level of T3, T4 inserum of FOS group was higher than control group; 3 The level of Ig G, Ig M in serum of FOS group werehigher than control group（P〈0.05）; 4 The amount of Lactobacillus and Bifidobacterium in feces of FOSgroup were higher than control group（P〈0.05）, the amount of E.coli in feces of FOS group was lower thancontrol group. It was concluded that FOS can improve the performance and immunity and intestinal floraof replacement gilt in varying degrees. These results can apply to production in the future.
