Abstract

The dynamics of growth of body weight, average daily gain, relative growth rate, increasing multiplicity live weight Simmental heifers, Ukrainian black and white dairy and ayrshyrskoyi species in a particular population, and also the growth prediction of live weight at certain ages ontogeny.

Found that animals age and average daily relative growth rate of live weight decreased, and the multiplicity of its increasing steadily. At birth Simmental heifers had an average live weight – 38 kg, at 3 months of age – 106, 6 months –177 in 9 months - 236 in 12 months – 295 and 18 months in 400 kg. They prevailed on this feature representatives ayrshyrskoyi species in the above mentioned age periods, respectively, 8, 14, 19, 26, 28 and 42 kg, and Ukrainian peers black and white dairy cattle at 3, 8, 12, 37, 16 20 kg. Average daily gain in the first, second and third semester were highest in symentaliv (772, 665 and 582 g) and the lowest in ayrshyriv (711, 605 and 505 g), intermediate heifer place occupied Ukrainian black and white dairy breed (722, 633 and 561 g). Simmental Heifers also distinguished high genetic potential growth of body weight, which the average rank for the entire period was 55,9 ± 1,05 %, heifers Ukrainian black and white dairy cattle were slightly lower rank – 50,9 ± 0,19 % and lowest rank was ayrshyrskoyi breed heifers - 45,6 ± 1,02%. Simmental cows according to their genetic potential to reach adulthood live weight 634-640 kg, and representatives of Ukrainian black and white dairy breeds and ayrshyrskoyi respectively 554-595 and 519-558 kg.
