摘　　要：[目的]为今后鼠李糖乳杆菌益生素的开发应用奠定基础。[方法]对照组猪饲喂基础日粮,试验I组和II组分别饲喂添加2和4ml/头鼠李糖乳杆菌益生素(RLB)的基础日粮,研究鼠李糖乳杆菌益生素对猪生产性能及部分血清学指标的影响。[结果]试验I组和II组妊娠母猪的死产、畸形、木乃伊和弱仔猪的总数量比对照组减少36.36%和54.55%,且平均初生重提高5.38%和10.00%;试验I组和II组断奶仔猪的平均重量比对照组提高1.31%和2.96%;与对照组相比,试验I组和II组断奶仔猪的平均日增重分别提高5.03%和8.06%,料重比分别降低4.07%和5.81%,断奶仔猪的腹泻率分别降低74.90%和100.00%;试验I组和II组小猪的平均日增重较对照组分别提高1.60%和6.79%,料重比分别降低2.05%和5.13%。[结论]RLB可使断奶仔猪血清葡萄糖、Ig A、白蛋白和总蛋白含量升高,血清胆固醇和Ig G含量降低;RLB可以提高妊娠母猪、哺乳母猪、断奶仔猪和小猪的生产性能。[Objective] The research aimed to lay the foundation for the development and application of Lactobacillus rhamnosus probiotics in future. [ Method] The pigs in control group was fed with basal diet and the pigs in test group I and II were fed with the basal diet supplemented with 2 and 4 ml per head of Lactobacillua Rhamnosus probiotics （RLB）. The effects of Lactobacillus rhamnosus probiotics （RLB）on the production performance and some serological indices of pigs were studied. [ Result] The number of stillbirths piglets, malformed piglets, mummified piglets and weak piglets of pregnant sows in test group I and II decreased 36.36% and 54.55% than that in control group, and the average birth weight of piglets in test group I and II increased by 5.38 % and 10.00 % than that in control group. The average weight of weaned piglets in test group I and II increased by 1.31% and 2.96 % respectively than that in control group. Compared with control group, the average daily gain（ADG） of weaned piglets in test group I and II increased by 5.03% and 8.06% respectively than that in control group. The feed-gain ratio（FCR） of weaned piglets in test group I and II decreased 4.07 % and 5.81% respectively than that in control group. The diarrhea incidence of weaned piglets in test group I and I[ decreased 74.90% and 100.00% respectively than that in control group. The average daily gain（ADG）of piglets in test group I and II increased 1.60 % and 6.79 % respectively than that in control group and FCR of piglets in test group I and II decreased by 2.05 % and 5.13 % respectively than that in control group. [ Conclusion] The contents of serum glucose, IgA, albumin and total protein of weaned piglets could be increased by RLB, and the contents of serum cholesterin and IgG. could be decreased by RLB. And the production per- formanee of pregnant sows, milking sows, weaned piglets and piglets could be increased by RLB.
