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.(AU)
