Abstract:

This study was conducted to elucidate the effects of glucose oxidase (GOD) on growth performance and serum biochemical indicator of piglets.Sixty piglets were randomized in three groups,control group (basal diet),experimental group 1(basal diet added 100 g/t olaquindox,75 g/t aureomycin,60 g/t oxytetracycline calcium) and experimental group 2 (basal diet added 400 g/t GOD).Each group had four replicates and each replicate had five piglets.The experiment lasted 30 d.The growth performance during the experiment and the serum biochemical indexes at the ending of the experiment were measured.The results showed that:For the pigs in experimental group 2,the final body weight,ADG,the level of IL-2,IL-4,IgA,lgG,IgM and TNF-α were all significantly higher (P<0.05),while the ADFI,F/G and surem AST activity were significantly lower (P<0.05) than that in control group and experimeatal group 1;The serum level of MDA was significantly lower than that in control group (P<0.05),while the IFN-γ level was significantly higher than control group (P<0.05);The other serum biochemical indexes,such as the activities of ALT,GSH-Px and SOD,the level of TP,ALB and GLB,and T-AOC had no significantly change(P>0.05).In conclusion,adding 400 g/t GOD in diets could improve the growth performance and antioxidant and immune ability,alleviate liver damage of piglets.
