To neutralize mycotoxins entering the digestive tract with feed, Probiotic and antioxidants are increasingly used. They are introduced into compound feeds to restore the normal micro flora in the gut, activate feed fermentolysis, strengthen the immune system and increase hens egg productivity. The research aims to study the effect of probiotic Bifidum SHG and antioxidant Santochinum on egg productivity, physico-chemical and incubation properties of eggs of layers whose feed has a tolerant level of aflatoxin B1. The objects of research were layers of cross Smena-7. The results were statistically processed by Students t-test using mathematical analysis software package Microsoft Excel. Feeding probiotic and preparation Santochinum as a part of mixed feed with the tolerant level of aflatoxin B1 contributed per average layer in the third test group to increase egg production by 13.2%. The highest average eggs weight had hens of the third test group, which in this indicator exceeded the control counterparts by 2.67%. Combined application of these preparations had the best effect on biochemical composition of eggs of birds from the compared groups. For layers of the third test group it was as superiority in the presence in the egg yolk of dry matter by 1.48%, protein by 2.00%, vitamin A by 18.2% and vitamin E by 12.0%, as well as in the concentration of dry matter in egg white by 1.68% and protein by 1.25%. Hens of the third test group outperformed the control counterparts in such morphological indicators of eggs, as the shape index by 1.70%, yolk index by 2.66%. Layers of the third test group surpassed the control counterparts in the yield of hatching eggs by2.30% and fertilized by 1.90%, as well as in the chick yield of the number of incubated eggs by 3.70%.
