Abstract:

This study was conducted to investigate the effects of soluble corn fiber (Fibersol-2) supplementation in diet on growth performance, biochemical indexes of serum and anti-oxidative capacity in piglets. A total of 448 hybird piglets (Duroc×Landrace×Large white) with similar body weight of 28 days old were randomly assigned into 4 dietary treatments, 8 replicates in each treatment with 14 piglets each, and fed a basal diet supplemented with 0, 1, 2 and 4 g·kg-1 Fibersol-2, respectively. The total experiment lasted for 35 d including 7-d pre-test and 28-d test, and an average initial body weight of piglets in the test was (9.65±0.44) kg. At the end of the test, one pig per replicate (near to the average body weight of the replicate) were weighed, slaughtered and the samples of liver and serum were collected and detected. The results showed that:1) The diets added Fibersol-2 did not significantly affect the growth performance and apparent nutrient digestibility of piglets (P>0.05). 2) Compared with the control group, Fibersol-2 supplementation significantly decreased the contents of triglyceride, albumin, total protein and the ratio of albumin to globulin, and markedly increased the content of urea nitrogen (P<0.05) in serum. Fibersol-2 supplementation of 1 and 4 g·kg-1 significantly increased globulin content in serum(P<0.05), Fibersol-2 supplementation of 2 and 4 g·kg-1 markedly decreased total cholesterol content in serum (P<0.05), and Fibersol-2 supplementation of 4 g·kg-1 significantly reduced glucose content (P<0.05) in serum. 3) Compared with the control group, Fibersol-2 addition significantly enhanced the activity of glutathione peroxidase (GSH-Px) in serum(P<0.05) and catalase (CAT) in serum and liver (P<0.05), respectively, but significantly decreased malondialdehyde (MDA) content in liver (P<0.05); Fibersol-2 supplementation of 2 and 4 g·kg-1 markedly increased total antioxidant capacity (T-AOC) in serum (P<0.05), and Fibersol-2 supplementation of 4 g·kg-1 significantly increased the activity of superoxide dismutase (SOD) in serum and liver (P<0.05), GSH-Px and T-AOC in liver (P<0.05), however, significantly reduced MDA content in serum (P<0.05). Under the experimental condition, Fibersol-2 supplementation could improve the immunity, antioxidant capacity of piglets, decrease the levels of glucose and lipids in serum, and promote the health of piglets.
