It was found that there is a strong correlative relation between the level of carotenoids in the ration of breeding hens during the reproductive period and the content of lipid peroxidation products in their liver and liver of embryos. In particular, increasing of the level of carotenoids in the mixed fodder for chickens from 8 g to 32 g per tonne during the intense oviposition reduces MDA level and diene conjugates as well as in the liver of adult hens, as in the liver of embryos before the hatching, which is an important biochemical mechanism during the oxidative stress prevention of one-day chickens.
