It was studied peculiarities the red white belted breed of the formation of prooxidant and antioxidant homeostasis in plasma and sperm of boars of the red white belted breed during the period of a formation of sexual function. It was determined that a level of sperm production in young boars from 5-th to 7-th month of a life substantially increase. Receiving two ejaculates a week from boars of 9-th – 10-th month age mainly doesn’t cause lowering the quality of sperm production. During the period of a formation of sexual function in plasma and sperm of young boars, the processes of FRPО are accelerated, a level of antioxidant enzymes (SOD, CT) is increasing, but not enzymes antioxidants (GT) are lowering. The most intensively these processes occur during 6-th and 8-th months of their development. The course of processes FRPО in plasma of sperm in young boars in the comparison with sperm occur less intensively.
