Infl uence of the exercise regime on the quality indicators of sperm production in breeding boars

In the pig breeding industry, the quality of sperm obtained from breeding boars plays an important role in the issue of reproduction. The purpose of the research was to investigate the eff ect of exercise regime on the quality indicators of sperm production in breeding boars. The research was carried out at the Tyumensky Pig Complex LLC in the Tyumen Region. For the research 3 groups of boars were formed with 10 heads in each. The control group did not receive exercise, the 1st experimental group received passive exercise, the 2nd experimental group received active exercise. It was found that the rectilinear motility of sperm, which aff ects the fertilizing ability of semen was in the 1st experimental group of boars 87.0 %, which was by 2.8 abs.% higher than in other groups. Also, more sperm doses were obtained from semen with high rectilinear motility with the same volume and concentration indicators In the groups of boars without exercise and with active exercise, 5.7 % of dead sperm were found, which was by 0.8 abs.% more than in the analogs that received passive exercise (p < 0,05). In the 1st experimental group of boars with passive exercise, the lowest percentage of sperm with defects was found, which aff ects the efficiency of insemination and the quality of the off spring. It was found that passive exercise had a more favorable eff ect on the qualitative indicators of sperm of the breeding boars of the 1st experimental group compared to active exercise (2nd experimental group) and its absence (control group). The use of passive exercise regime for breeding boars had a positive eff ect not only on the quantitative indicators of semen, but also on the quality of sperm and can be recommended at the enterprise when housing breeding boars.
