The influence of the of breeding value size of Holstein bulls on the gain of live weight

The work purpose was to determine genomic breeding value and the influence of its size on gain of live mass of the bulls of Holstein breed received and grown up to one-year age in climatic conditions of Holland (22 heads) and Canada (5 heads) then grown in the conditions of Central Siberia on Krasnoyarsk pedigree farm up to 2 years of age. The tasks were to determine genomic breeding value of controlled bulls during the age period of 12-24 months, to give the analysis of live weight at 12, 18 and 24 months, the growth rate of live weight during age periods of 12-18, 18-24 and 12-24 months, to establish the influence of the size of genomic breeding value of the bulls on live weight at 24-months of age, on the growth rate of live weight in absolute and relative val- ues during the age period of 12-24 months by comparison of the size of the difference of these indicators in each bull, the average size of all genotyped bulls and indicators of genomic breeding value of each bull...
