The aim of the research was to genotype controlled Holstein bulls on genomic predicted breeding value, to study the effectiveness of the influence of genomic breeding values on quantitative and qualitative indica-tors of native and cryopreserved sperm and its fertility. The diet of steers was received and average daily gain of live weight was from 900 to 1000 g. The weighing of steers took place every month, on 25-th day before morning feeding. Nutritional value of the diet was ad-justed once a month, taking into account the changes in live weight and palatability of feed according to the norms of RAAS (2003). All fodder used for feeding, was studied according to nutritional value in FSBI CAS "Krasnoyarsky". The studies found out that the amount of genomic breeding values did not have any impact on reproductive ability of bulls, and to a greater extent de-pended on individual indices of the bulls: 8 bulls having GPTA with a value above the mean of all genotyped, in 4 the reproduction of semen ejaculates exceeded the average by 22.0 %, in 4 it was 36.7 % lower, in 3 the output of native sperm exceeded the average by 40.2 %, in 5 it was24.9 % lower, in 3 the output of cryo-preserved sperm exceeded the average for 67.80 %, in 5 it was less than 36.9 %, 2 fruitful inseminations ex-ceeded the mean value by 10.4 %, and in 6 it was 9.3 % lower; among 10 bulls with the value of GPTA below average in all genotyped, in 3 the number of ejaculates exceeded the mean value by 47 %, in 7 it was less than 37.2 %, in 5 the yield of native sperm exceeded the av-erage by 38.1 %, in 5 it was 66.1 % lower, in 5 the out-put of cryopreserved semen it was higher on average by 46 %, in 5 it was 53 % lower, in 4 fruitful insemination was more than average by 5.8 %, in 6 it was less than 10.5 %.
