Summary. The studies were carried out on heifers (progeny of Simmental fresh cows) of Bredy beef type, obtained after the use of sires of Canadian selection Rambo 105888518 and Ricardo 106314782 and the progeny of sire of Bredy beef type Salute 1223.

The animals were kept according to the technology adopted in beef cattle. The impact of the Canadian breeding bulls on the process of increasing body weight over periods of growth was evaluated. According to the results of weighing, absolute growth per unit of time was calculated by periods of growth, as well as the average daily increase in live weight.

The young stock, obtained from fresh cows, grew well and developed well during the suckling period, and in live weight at 8 months of age met the requirements of the elite class, the elite record.

The cows from the sire Salyut 1223 we marked for their he highest live weight, which surpassed the herdmates received from the Rambo bull 105888518 by 10 kg (P≤0.001), animals obtained from the bull Ricardo 106314782, which in turn exceeded analogues from Rambo by 7.8 kg (P≤0.001).

After weaning mother cows, the live weight of all the studied groups of heifers in all age periods corresponded to the value of the elite-record class. At the same time, the progeny of Salyut 1223 was characterized by the best body weight and growth intensity. Thus, in terms of absolute live weight, they surpassed herdmates obtained from Rambo by 24.6 kg (P≤0.001) and analogues obtained from Ricardo 106314782 by 20.9 kg (P≤0.001).

During the growing period, the average daily gain was quite high and amounted to 712.4 g. As a result, all studied groups of heifers from all three sires were assigned to the highest assessment class elite record.

Key words: heifers, Simmental, estimation, descendant, live weight, average daily gain, sire.
