The article presents the research results of the effect of different doses of the seleniferous preparation«E-selenium» (produced in Russia by«Nita-Farm») for the implementation of the sexual potential and the dynamic characteristics of the semen of male minks.Study was conducted on the basis of «Zolotonoshskoe zvirohospodarstvo» Cherkasy region on 60 males mink genotype Scanglow of scandinavianselection. By group-analogue method there were formed a control and two experimental groups (20 minkswithin each group). Experimental group 1 (D1) had the research medication injection per 0.04 mh/kg body weight, the experimental group 2 (D2) per 0.02 mh/kg live weight. Control group of animals kept at the main diet.

The study of reproductive function found that a single injection of the preparation «E-selenium» in the calculation of 0.04 mg/kg of live weight in the run-up to the male mink breeding season (the last ten days of February) allowed to increase the performance of their reproductive capacity.

It was shown in improvement of sexual activity for 2.7%, increase of polygamous ability for 8.2%, impregnating ability for 8.7% and reduction of number of unsuccessful whelping females for 54.8% in comparison with similar indicators of control group of males. Females who became covered by producers of this group bred 6.5% more, than females covered with males of control group.

The analysis of dynamic characteristics of sperm of male examinees showed reliable advantage in 8.93% on an indicator of the general mobility of male sperm cells of the first skilled group, other indicators had not considerable distinction and authentically didn't differ from similar values of males of control group.
