摘　　要：试验旨在研究日粮中添加假蒟和番石榴叶复合提取物对断奶仔猪生长性能和血清指标的影响。选择200头21日龄断奶仔猪,随机分为2组,每组5个重复,每个重复20头猪。对照组仔猪饲喂基础日粮,试验组在基础日粮中添加200 mg/kg的复合植物提取物。试验期21 d。结果显示,各组仔猪生长性能无显著差异(P>0.05)。与对照组相比,试验组仔猪血清中胆固醇(CHOL)和低密度脂蛋白胆固醇(LDL-C)的含量显著降低(P<0.05),谷胱甘肽过氧化物酶(GSH-Px)活性显著升高(P<0.05),血清中白细胞介素-4 (IL-4)、白细胞介素-10 (IL-10)和转化生长因子-β(TGF-β)含量显著升高(P<0.05),白细胞介素-1β(IL-1β)、白细胞介素-6 (IL-6)和肿瘤坏死因子-α(TNF-α)含量显著降低(P<0.05),血清中内毒素(ET-1)含量和二胺氧化酶(DAO)活性显著降低(P<0.05)。研究表明,日粮中添加复合植物提取物可以提高断奶仔猪机体的抗氧化性能和免疫功能,改善仔猪肠道黏膜屏障功能。The experiment was conducted to study the effect of composite plant extracts Piper sarmentosum Roxb. and guava leaf on growth performance and serum indexes of weaned piglets. A total of 200 21-day-old weaned piglets were selected and randomly divided into two groups, with five replicates in each group and 20 piglets in each replicate. Piglets in control group were fed with a basal diet, the piglets in experimental group were fed with the basal diet supplemented with composite plant extracts at 200 mg/kg. The experimental period was 21 d. The results showed that there was no significant difference on growth performance of piglets among the groups(P>0.05). Compared with control group, the experimental group supplemented with the compound plant extract in the diet significantly decreased the serum cholesterol(CHOL) and low-density lipoprotein cholesterol(LDL-C) content of piglets(P<0.05), glutathione peroxidase(GSH-Px)activity was significantly increased(P<0.05), serum content of interleukin-4(IL-4), interleukin-10(IL-10) and transforming growth factor-β(TGF-β) were significantly increased(P<0.05), the content of interleukin-1β(IL-1β),interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) were significantly decreased(P<0.05), and serum endotoxin(ET-1) content and diamine oxidase(DAO) activity were significantly decreased(P<0.05). The study indicates that adding compound plant extracts to diet can improve the antioxidant performance and immune function of weaned piglets, and improve the intestinal mucosal barrier function of piglets.
