摘要
This experiment was to investigate ginger extract on production performance,antioxidant ability and immunity of laying hens.A total of 600 Hy-Line brown laying hens aged at 25 wk old were randomly divided into 2 treatments,4 replicates per treatment,75 layers each replicate.The control group hens were fed a basal diet;the experimental group hens were fed basal diets with 0.1%ginger extract.The results were shown as follows:1)ginger extract significantly enhanced laying rates(P<0.05)and daily egg weight(P<0.05),substantially reduced the ratio of feed to egg(P<0.05)of the hens;2)ginger extract did not change the activities of glutathione peroxidase(GSH-PX)and total antioxidant capacity(TAOC)but significantly improved plasma superoxide dismutase(SOD)activity(P<0.05),reduced malondialdehyde(MDA)content(P<0.05)of the birds;3)ginger extract did not affect the contents of serum total protein(TP),albumin(ALB),globulin(GLB),but significantly increased lysozyme(LZM)activity(P<0.05);4)ginger extract also significantly reduced plasma prostaglandin E2(PGE2)content(P<0.05).This study shows that ginger extract not only can improve the birds’antioxidant capacity,enhance immune function,but also has a potential of reducing inflammatory response.
