本试验研究了复合益生菌对羔羊生产性能及白细胞介素水平的影响。将20只羔羊随机均分成对照组和复合益生菌组，分别饲喂基础日粮和含0.2%复合益生菌的基础日粮。试验期56 d。试验过程中，测定始重、末重、增重、日采食量和料重比等生产性能指标；在试验0、28、56 d 时，测定血浆中白细胞介素-1（IL-1）和白细胞介素-2（IL-2）水平。结果表明：复合益生菌组羔羊平均末重和平均增重分别比对照组提高了1.94%和14.08%，而平均日采食量较对照组降低了2.41%，但差异均未达到显著水平（P＞0.05）。复合益生菌组羔羊料重比较对照组降低了13.74%，差异显著（P＜0.05）。在28 d和56 d时，复合益生菌组羔羊血浆IL-1浓度分别比对照组提高了8.45%和26.86%，但差异未达显著水平（P＞0.05）。在28 d时，复合益生菌组羔羊血浆IL-2浓度比对照组提高了2.19%，但差异未达显著水平（P＞0.05）；在56 d时，复合益生菌组羔羊血浆IL-2浓度比对照组提高了27.33%，差异显著（P＜0.05）。结果提示，复合益生菌有提高羔羊生产性能和血浆IL-1、IL-2水平的作用。
本試驗研究瞭複閤益生菌對羔羊生產性能及白細胞介素水平的影響。將20隻羔羊隨機均分成對照組和複閤益生菌組，分彆飼餵基礎日糧和含0.2%複閤益生菌的基礎日糧。試驗期56 d。試驗過程中，測定始重、末重、增重、日採食量和料重比等生產性能指標；在試驗0、28、56 d 時，測定血漿中白細胞介素-1（IL-1）和白細胞介素-2（IL-2）水平。結果錶明：複閤益生菌組羔羊平均末重和平均增重分彆比對照組提高瞭1.94%和14.08%，而平均日採食量較對照組降低瞭2.41%，但差異均未達到顯著水平（P＞0.05）。複閤益生菌組羔羊料重比較對照組降低瞭13.74%，差異顯著（P＜0.05）。在28 d和56 d時，複閤益生菌組羔羊血漿IL-1濃度分彆比對照組提高瞭8.45%和26.86%，但差異未達顯著水平（P＞0.05）。在28 d時，複閤益生菌組羔羊血漿IL-2濃度比對照組提高瞭2.19%，但差異未達顯著水平（P＞0.05）；在56 d時，複閤益生菌組羔羊血漿IL-2濃度比對照組提高瞭27.33%，差異顯著（P＜0.05）。結果提示，複閤益生菌有提高羔羊生產性能和血漿IL-1、IL-2水平的作用。

The experiment was conducted to determine the effects of complex probiotics on growth performance and in-terleukin levels in lambs.Twenty lambs were randomly assigned into two dietary treatment groups (ten per group)for a 56 days study,which were fed basal diets or basal diets supplemented with 0.20 percent of complex probiotics,respectively.Dur-ing the entire experiment period,overall growth performance of lambs,including initial weight,final weight,average body weight gain,feed intake and feed/gain were determined.Plasma interleukin-1(IL-1)and interleukin-2(IL-2)levels were ana-lyzed at d 0,28 and 56 of the experiment.The results showed that:at the end of the trial,the final weight and average body weight gain of probiotics group were approx 1.94%and 14.08%higher than those of control group (P>0.05),while feed in-take of probiotics group was approx 2.41%lower than that of control group (P>0.05).However,the feed/gain of probiotics group was approx 13.74%lower than that of control group (P < 0.05).Plasma IL-1 levels of probiotics group were approx 8.45%and 26.86%higher than that of control group (P>0.05)at d 28 and 56 of the experiment.At d 28 of the experiment, plasma IL-2 levels of probiotics group was approx 2.19%higher than that of control group(P>0.05),however,at d 56 of the experiment,plasma IL-2 levels of probiotics group was approx 27.33%higher than that of control group (P<0.05).The re-sults indicated that complex probiotics had positive effects on growth performance,IL-1 levels and IL-2 levels in lambs.
