PROOXIDANT-ANTIOXIDANT HOMEOSTASIS IN THE SPERM OF FERTILE BOARS DEPENDS ON THE INFLUENCE OF DIFFERENT FACTORS

Abstract:

The purpose of the study was to establish the peculiarities of the formation of pro-oxidant-antioxidant homeostasis in sperm and seminal plasma of breeding boars depending on the season and the intensity of their use. 10 adult breeding boars of a large white breed aged from 18 to 36 months were selected for the experiment – analogues in terms of the quality of sperm production. Breeding boars were fed according to the norms of the Institute of Pig Breeding and Agro-Industrial Production of the National Academy of Agrarian Sciences of Ukraine. It has been established that the best indices of sperm production characterize animals in the spring period. In the summer period, the quality of sperm in breeding boars probably decreases. Such changes are accompanied by a significant decrease in catalase activity by 30.6 % (p<0.01) and a significant accumulation of the TBC-active complexes’ content by 46.9 % (p<0.01). The quality of sperm production of breeding boars is significantly dependent on the mode of their use. It was found that increasing the intensity of using boars twice a week does not contribute to a significant acceleration of peroxidation processes.
