Effects of Supplementary Feeding of Sows with Fermented Asparagus By-Product on Antioxidant Capacity, Immune Function and Contents of Inflammatory Factors in Serum of Sows and Suckling Piglets
摘要
Abstract
This study was conducted to investigate the effects of supplementary feeding of sows with fermented asparagus by-product on antioxidant capacity, immune function and the contents of inflammatory factors in ser-um of sows and suckling piglets from late-pregnancy to the end of lactation. Fifteen pregnant sows with similar body condition, parity and parturition time were randomly assigned to three groups with five replicates per group and one sow per replicate. Sows were fed a basal diet supplemented with 0, 0.25 and 0.50 kg fermented asparagus by-product each day in groups A, B and C, respectively. The experiment lasted from day 85 after pregnancy to day 21 after delivery. Blood samples of sows were collected from the auricular vein at the time of sows delivery and piglets weaning, and blood samples of suckling piglets aged at 10 and 21 days were collected from anterior vena cava, and serum indexes were measured, respectively. The results showed as follows: 1) the activity of superoxide dismutase ( T-SOD) in serum of sows in group C was significantly higher than that in control group at piglets weaning ( P<0.01) , and the content of malondialdehyde ( MDA) in serum in group C was significantly lower than that in control group at sows delivery and piglets weaning ( P<0.01) . The activity of T-SOD in serum of suckling piglets aged at 10 days in group B was significantly higher than that in control group (P<0.05), and the content of MDA in serum in group B was significantly lower than that in control group (P<0.05). 2) The content of growth hormone (GH) in serum of sows in group C was significantly higher than that in control group at sows delivery ( P<0.05) . 3) The contents of immunoglobulin A ( IgA) and immunoglobulin G ( IgG) in serum of sows in group C were significantly higher than those in control group at sows delivery ( P<0.05) . 4) The content of interleukin-6 ( IL-6) in serum of sows in groups B and C was sig-nificantly lower than that in control group at sows delivery and piglets weaning (P<0.01). The content of tumor necrosis factor-α ( TNF-α) in serum of sows in group C was significantly lower than that in control group at piglets weaning (P<0.05). The content of TNF-α in serum of suckling piglets aged at 10 days in group C was significantly lower than that in control group ( P<0.05) . It is concluded that supplementary feed-ing sows with 0.50 kg fermented asparagus by-product each day can improve antioxidant capacity and immune function, increase GH content and decrease the inflammatory response of sows, meanwhile, increase antioxi-dant capacity and decrease inflammatory response of piglets.关键词
