Effect of Glucose Oxidase on Performance and Serum Biochemical Parameters of Laying Hens

doi:10.7668/hbnxb.2009.S1.068

Abstract

Abstract: This experiment was to investigate the effect of Glucose Oxidase on and serum biochemical parameters oflaying hens. 180 twenty- six- week- old Hyline layers were randomly allotted to 5 treatments, Laying Hens in treatments??, ??, ??, ?? and ?? received basal diets with the addit ion of 0, 0. 1%, 0. 2%,0. 3%, 0. 4% glucose oxidase. The resultsshows that laying hens fed the addition of 0. 1%, 0. 2%,0. 3%, 0. 4%glucose oxidase, compared with the control group, theegg product ion increased by 11??01%( P > 0??05),12??34%( P > 0??05),16??06%( P< 0??01),13??79% ( P< 0??05) ; the broken(soft) eggshell rats decreased by 32??77% ( P> 0??05),33??45%( P > 0??05),49??66%( P < 0??05),33??11%( P> 0??05) ;the additions of 0??3% and 0??4% glucose oxidase significantly enhance( P < 0??05) the feed conversion ratio. Laying hensfed the addit ion of 0??2%~ 0??4% glucose oxidase significantly increased the serum ALB, and had the trend of increasingthe in serum GLO, Ca,P,AKP, GPT and GOT, and reducing the serum CHOL and TG, but the differences were not signif-icant( P> 0??05) .The addition of 0??4% glucose oxidase significantly reduced the levels of CK( P< 0??05) .
