The investigation of the growth, development and productive use of daughters of bulls Volyn meat breed, semen which is intended for Long-Term storing. Analysis of individual data 30 cows which belong to the lines Krasavchik 3004 and Yamb 3066. The dynamics of changes of live body weight in cows depending on the age (at birth, in 8, 12, 15, 18 month, 5 years). The highest average values of live weight were observed in the daughters of a bull Kovryk 2430. In the study the animals were observed regular decrease of the relative growth rate of live body weight with age. In the period from 8 to 12 and from 15 to 18 months, the highest growth rate was observed in the daughters of the bull Javor 2391 (38.85 %). In the period from 12 to 15 months increased more intensively live weight daughters Cactus 2491 (17.96 %).
In the animals observed are breed specific exterior features and development of meat forms. Theresults of measurements of the body parts higher values are typical for daughters Kovryk 2430.In the cows an increase level of dairy productivity with subsequent calving. In the context of the three calving milking becomes from 172 kg to 240 kg. The highest live weight of calves at weaning was in a group of daughters of a bull Kovryk 2430.
Daughters in the bulls be possessed of desirable by indicators of live body weight and level of dairy productivity,which contributes efficiency of agrowing and implementing genetic potential in the young.
