Effect of composite plant extracts on growth performance and serum indexes of weaned piglets

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.
