The influence of the value of genomic breeding values of the bulls on the reproduction of native sperm and its fertile ability

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...
