摘　　要：文章旨在探究日粮添加紫苏籽提取物(Perilla seed extract,PSE)对仔猪生长性能、免疫指标和肠道菌群结构的影响。试验将192头杜长大三元杂交猪(均重5.41±0.27 kg)随机分为4组,每组6个重复,每个重复8头。分别向基础日粮中添加0(对照组)、120(试验组I)、240(试验组Ⅱ)和480 mg/kg(试验组Ⅲ)的PSE作为试验日粮,试验为期28 d。试验组Ⅲ仔猪末重显著提高11.18%(P<0.05)、平均日增重显著提高6.84%(P<0.05),料肉比显著降低8.94%(P<0.05);此外,PSE对仔猪采食量及腹泻率均无显著影响(P<0.05)。与对照组相比,试验组Ⅲ仔猪血清肿瘤坏死因子(TNF-α)含量显著降低(P<0.05);试验组I、Ⅱ和Ⅲ仔猪血清白细胞介素-1β(IL-1β)、含量显著降低(P<0.05);试验组Ⅲ仔猪血清白细胞介素-6(IL-6)含量显著降低(P<0.05);试验组Ⅱ仔猪血清白细胞介素-10(IL-10)含量显著降低(P<0.05);试验组Ⅱ和Ⅲ仔猪血清补体C3含量显著提高(P<0.05);此外,各组间IL-2、IL-8、IL-10及补体C4含量均无显著差异(P>0.05)。与对照组相比,试验组I、Ⅱ和Ⅲ组仔猪回肠菌群Shannon指数显著提高(P<0.05);试验Ⅱ和Ⅲ组Ace指数和Chao 1指数显著提高(P<0.05);此外,各组间Simpson、Sobs、香农维纳和辛普森维纳指数均无显著差异(P>0.05)。总之,本试验结果显示,适量添加PSE(480 mg/kg)可增强仔猪免疫力,促进生长发育。The experiment aims to explore the effects of adding perilla seed extract to feed on the growth performance,immune indicators,and gut microbiota structure of piglets.192 Duroc three yuan hybrid pigs(average weight 5.41±0.27 kg)were randomly divided into 4 groups,with 6 replicates in each group and 8 pigs in each replicate.Add 0(control group),120(experimental group I),240(experimental groupⅡ),and 480(experimental groupⅢ)mg/kg of perilla seed extract to the basic diet as feed for each experimental group for a total of 28 days.The final weight of experimental groupⅢpiglets significantly increased by 11.18%(P<0.05),and the average daily weight gain significantly increased by 6.84%(P<0.05).The feed to meat ratio significantly decreased by 8.94%(P<0.05);In addition,perilla seed extract had no significant effect on feed intake and diarrhea rate of piglets(P<0.05).Compared with the control group,the serum TNF-αcontent of piglets in experimental groupⅢwas significantly reduced(P<0.05);The serum IL-1βcontent of piglets in experimental groups I,Ⅱ,andⅢsignificantly decreased(P<0.05);The serum IL-6 content in experimental groupⅢpiglets significantly decreased(P<0.05);The serum IL-10 content in experimental groupⅡpiglets significantly decreased(P<0.05);The serum complement C3 content of piglets in experimental groupsⅡandⅢsignificantly increased(P<0.05);In addition,there were no significant differences in the levels of IL-2,IL-8,IL-10,and complement C4 among the groups(P>0.05).Compared with the control group,the Shannon index of ileal microbiota in experimental groups I,Ⅱ,andⅢsignificantly increased(P<0.05);The Ace index and Chao 1 index of groupsⅡandⅢin the experiment were significantly increased(P<0.05);In addition,there was no significant difference in Simpson,Sobs,Shannon Wiener,and Simpson Wiener indices among the groups(P>0.05).In summary,the data from this experiment showed that adding an appropriate amount of perilla seed extract(480 mg/kg)can enhance piglet immunity and promote growth an
