The Effect of Dietary Glucose Oxidase Supplementation on Production Performance, Egg Quality and Nutrient Digestibility in Laying Hens

ABSTRACT The study was conducted to investigate the effect of GOX on performance, egg quality, and nutrient digestibility in laying hens. In total, 432, 50-week-old Hy-Line brown breeder hens were assigned into four treatments, and fed a basal diet with GOX at 0, 100, 200 and 300 units for 10 weeks, respectively. A Quadratic decrease in FI in week 3 (p<0.05) and linear increase in egg production in week 6 to 10 and overall experiment period (p<0.05) and Quadratic increase in egg production in week 7 (p<0.05), a linear decrease in broken egg rate in week 6 (p<0.05) a quadratic increase in egg weight on day 14 (p<0.05), alinear increase in egg weight on day 28 (p<0.05), and linear decrease in yolk color on day 7 (p<0.05), a linear increase in yolk color on day 42 and day 70 (p<0.05), and linear increase in haugh unit on day 28 and 70 (p<0.05), a linear increase albumen height on day 28 and day 56 (p<0.05), and linear decrease in shell color on day 14 (p<0.05) and day 28(p<0.05), a linear and quadratic increases in eggshell strength and eggshell thickness on day 56 (p<0.05), and linear increase in eggshell strength and eggshell thickness on day 70 (P0.05) were observed with the addition of GOX the the diet. Conclusion: This study suggested that the supplementation of GOX may have beneficial effects on feed intake and egg quality in laying hens.
