Results of research have shown, that in conditions of Grodno Breeding Enterprise at bulls-sires of a various genotype the level and quality of spermoproduction was a different. Sires of the specified genotypes authentically differed on volume of an ejaculate, activity and concentration of spermatozoa, and also on total of spermatozoa in an ejaculate (p0,001). The best survival rate of spermatozoa (4,4+0,1 hours) was observed at bulls-sires of the Hungarian selection. On a survival rate of spermatozoa bulls-sires of the Hungarian selection authentically (р 0,01) surpassed only bulls-sires of the Belarus selection. The highest indicators of spermoproduction at bulls-sires of these selections were observed during the spring period, and the lowest in the summer (volume of ejaculate and total quantity of spermatozoa р 0,01; concentration р 0,05)
