Abstract
The purpose. To study effect of different concentrations of vitamin E in combination to selenium upon reproductive function of males of a carp. Methods. Methodological basis of scientific researches is the microscopic study of cells of sperm with the use of computerized system CASA (Computer Assisted Semen Analysis). Results. Assessment of quality of sexual products of males of a carp is carried out by fixation of effect of addition into their ration of vitamin-mineral additive during prespawning season. Parameters of mobility and fertilizing ability of sperm are probed. It is determined that it is expedient to feed vitamin E (at the rate of 75 mg/kg of feedstuff) in a complex with selenium (at the rate of 0,3 mg/kg of feedstuff), considering raise of productivity of sperm. Increase in quantity of sperm with rectilinear-forward motion and speed of movement of sexual cells in particular is revealed. Conclusions. Addition in feedstuff of vitamin E and selenium in prespawning season positively influences quantity and quality of sexual products of males of a carp. In particular, total activity of sexual cells grows and the quantity of motionless ones decreases.

Key words: males of a carp, sexual products, spermatozoon, computer diagnosis, mobility, rectilinearly-forward motion, manege movement.
