Effects of copper citrate on physiological-biochemical parameters of ejaculate of sire boars

Revealing peculiarities of the course physiological and biochemical processes in formation parameters ejaculate allows effective correlation biological completeness spermatozoids based on use chelate compounds limiting microelements, particularly copper. The study was focused determining changes spermatogenesis during correction mineral nutrition. In experiment, we used adult boars same age, live weight quality ejaculates. They consumed copper citrate 45 day experiment doses higher than norm by 10% (1.5 mg per 1 kg combined feed) 20% (3 compared with control. We determined difference effects different ejaculates sire boars. Addition additive to feed exceeding promoted increase functional activity – mobility survival intake, which occurred against background acceleration peroxidation (increase concentration thiobarbituric acid active compounds) activation system antioxidant protection superoxide dismutase decrease level catalase sperm. At time, observed morphometric general length, width, length volume head. On 30, that had been consuming amounts above were have spermatozoids, their survivability, though a seen gametes. Further intake this element caused amount abnormal forms spermatozoids. Under action additive, metabolites lipid conjugated dienes acids compounds, also weakening antioxidative content reduced glutathione accumulation dehydroascorbic acid. Thus, facilitated morpho-functional activating protection. It would be promising conduct further research determine capacitation fertilization oocytes vivo vitro conditions.
