BREED FEATURES OF PROTEIN METABOLISM IN THE BOAR-SIRES ORGANISM

The data of proteins oxidative modification intensity in semen plasma and spermocyte plasma of Large White breed boar-sires and synthetic line SS23 are being studied. It is determined that the contents of the products of oxidative modification of sperm plasma of both animal groups under study is much higher compared to spermocyte plasma. The pattern in the distribution and content of oxidized forms of proteins in the Large White breed boar-sires and synthetic line SS23 is noted, due to the intensity of metabolic processes. Investigated semen of boar-sires contained a significant amount of sulfhydryl groups of proteins and low molecular weight thiols.

Key words: boar-sires, semen, the oxidative modification of proteins, the average weight molecules, thiol groups.
