The results of studies aimed at comparing turkey of the live weight of the middle and heavy cross Hybrid breeds with a white broad-chested rock were carried out. The study of the live mass and its growth dynamics over the periods of cultivation was carried out by weighing. The growth rate was estimated by absolute, daily and relative increments of live weight. According to the results of the research, it can be concluded that hybrid «Hybrid» and its crosses have a higher genetic potential of productivity, have high rates of growth and its intensity, which allows before slaughtering at 120 and 150 days, depending on the cross, to obtain turkeys with a high live weight of 10.83-23.20 kg, respectively.
