The experimental data on the effect of ferrous lactate on the qualitative parameters of sperm and the formation of prooxidine-antioxidant homeostasis in the semen of boars is represented. It was established that the incubation of whole semen during the day leads to a significant decrease in sperm motility by 9% and their survival rate of 9.8%. This decrease in the functional activity of spermatozoons occurs as a result of a shift in prooxidant-antioxidant homeostasis toward the acceleration of peroxidation processes
