The aim of this study was to investigate the effects of beta-glukan supplement on the basal diet of ovarian blisters exposed to bull (Pb) toxicity. A total of 112 Japanese bulbs (5 weeks) were randomly divided into 4 groups with a total of 28 bulbs, each of which was composed of 7 bulbs, with an average body weight similar in the beginning. The first group was given basal ration based on eggs-soya beans and without supplements (Control). The second group’s ratio was added 100 mg/kg of bullet (Pb (II) as acetate trihydrate) (Pb). The third group (Beta-glukan) has 100 mg/kg of beta-glukan. The last group was given basal ratio plus 100 mg/kg of bullet and 100 mg/kg of beta-glukan (Pb+Beta-glukan). At the end of the test, the live weights of the groups were similar. The effect of beta-glukan on the egg weight was not significant except for the 43-56 days (P<0.05), while the egg production (29-56 days) was very significant (P<0.001). The food consumption (P<0.01) and the benefit rate (P<0.001) of the beta-glukan supplementary groups were similar to the control group in the 1-56 days. In terms of egg quality parameters, the egg yellow index (P<0.01) has been negatively affected by the haugh unit and the ac index (P<0.001), the beta-glukan supplement has significantly improved the yellow index. As a result, the beta-glukan supplement to the ration has improved the egg quality parameters and egg performance of the bull toxicity exposed to the bull.
