Characteristics of meat productivity of Holstein and Ukrainian black-spotted dairy breed bullocks, which were grown using intensive technologies, are researched.
As a result of the research work, it was established that the live weight of Holstein breed bullocks is higher at all age periods of breeding and feeding.
The difference at the age of 2, 4 and 6 months was 2.1 kg; 25.2 kg (P>0.999) and 25.9 kg (P>0.999), accordingly. This overweight also occurs at the other age periods. At the age of 8, 10, 12 and 13 months, the live weight of the first group of bullocks was higher at 40.7 kg (P>0.999); 49.7 kg (P>0.999); 59.1 kg (P>0.999) and 62.1 kg (P>0.999), accordingly.
It was found that the realizable live weight of 454.2 kg was reached by Holstein breed bullocks at the age of 13 months, and the live weight of peers of the Ukrainian black-spotted milk breed at that age was only 392.1 kg, that is, they reached the live weight of 449.8 kg. later, namely at the age of 15 months
The growth rate of the experimental young was characterized by periodicity and irregularity.
The highest average daily increase (1343.7 g) had the animals of the Holstein breed in the period of 2-4 months. The bullocks of the Ukrainian black-spotted dairy breed exhibit a higher level of formation intensity (∆t=0.414) over the 2-4-6 months period than the peers of the Holstein breed (∆t=0.397). During 6-8-10 months period, the growth uniformity of the bullocks of researched breeds was estimated by the highest values of the coefficients (Ip=1.088 and Ip=1.068, accordingly), but the growth intensity was low (In=0.110 and In=0.079).
Thus, the determined indices of intensity of live weight formation, uniformity and growth power characterize the periodic and uneven increase in live weight of experimental bullocks at different speed and intensity of their growth, as well as the conditionality of the formation of meat productivity of the young of cattle dairy breeds.
