Effects of Illicium verum and Eucommia ulmoides Leaves Extracts on Immune Function and Antioxidant Capacity of Duroc× Landrace×Yorkshire and Chinese Native Licha?Black Weaned Piglets
摘要
Abstract
This study was conducted to investigate the effects of Illicium verum extracts ( IVE) and Eucommia ulmoides leaves extracts ( ELE) on immune function and antioxidant capacity of Duroc×Landrace×Yorkshire ( DLY) and Chinese native Licha?black ( LCB) weaned piglets. Forty?eight healthy DLY and 48 healthy LCB weaned piglets with similar body weight of (11.22±0.32) kg were randomly divided into 4 groups with 3 rep?licates per group and 8 piglets ( 4 DLY and 4 LCB piglets) per replicate. Piglets in control group were fed a basal diet, and the others in experimental groups were fed basal diets supplemented with 500 mg／kg IVE, 250 mg／kg ELE and 50 mg／kg chlortetracycline ( CHL) , respectively. The trial period lasted for 42 days after 7 days adaptation. The results showed as follows: 1 ) compared with control group, average daily gain ( ADG) , superoxide dismutase ( SOD) activity ( 24 and 48 h) of longissimus dorsi muscle and mRNA relative expression level of glutathione peroxidase 4 ( GPx4) of duodenum of DLY and LCB weaned piglets in IVE and ELE groups were significantly increased ( P＜0.05) , but urea nitrogen content in serum in IVE and ELE groups was significantly decreased ( P＜0.05 ). 2 ) Compared with control group, total protein content in serum of DLY and LCB weaned piglets in IVE group was significantly increased ( P＜0.05) , and peripheral blood lym?phocyte proliferation rate and immunoglobulin A ( IgA) content in serum of DLY and LCB weaned piglets in ELE group were significantly increased ( P＜0.05). 3) Average daily feed intake ( ADFI) , the ratio of feed to gain ( F／G) , spleen index, and serum urea nitrogen, low density lipoprotein ( LDL ) , immunoglobulin M ( IgM), immunoglobulin G ( IgG) and malondialdehyde ( MDA) ( 48 h) contents of LCB weaned piglets were significantly higher than those of DLY weaned piglet ( P＜0.05) , while ADG, serum high density lipo?protein ( HDL) content, glutathione peroxidase ( GSH?Px) activity ( 24 h) of longissimus dorsi muscle and mRNA relative expression level of GPx4 of duodenum and jejunum were significantly lower than those of DLY weaned piglet ( P＜0.05). 4) The interaction between piglets breeds and dietary additive had significant effects on ADG, ADFI, F／G and IgM contents in serum of weaned piglets ( P＜0.05). In conclusion, dietary IVE and ELE can increase antioxidant capacity and immune function of weaned piglets. The antioxidant and immune effects of IVE and ELE on DLY and LCB weaned piglets are different, self?immunity of LCB weaned piglets is better than that of DLY weaned piglets, while growth performance and antioxidant capacity of longissimus dorsi muscle, duodenum and jejunum are the opposite.[ Chinese Journal of Animal Nutrition, 2019, 31 (10) :4717?4728]关键词
