One of the intensively developing poultry farming industries in recent years is turkey farming. The share of turkey meat is 10% of the total poultry meat production in the world. In Russia, mainly for the production of poultry meat, and, in particular, turkey, Hybrid Converter and Big-6 crosses are used. In this regard, our goal was to compare the productive qualities of poultry by comparing the growth and development of turkeys of Hybrid Converter and Big-6 crosses. The assessment was carried out by studying the growth dynamics of absolute, average daily and relative body weight gains. Along with this, we also calculated the feed conversion and the meat productivity index. As a result, when comparing females and males by live weight, it was found that males surpassed females. The comparative characteristics of Hybrid Converter and Big-6 crosses in terms of live weight, absolute, average daily and relative live weight gains showed that the Hybrid Converter cross surpassed Big-6 in all analyzed indicators. The productive qualities of turkeys show that the absolute increase in body weight in females of the Hybrid Converter cross over the entire period compared with females of the Big-6 cross was higher by 92 g or 0.9%; in males by 895 g or 4.7%. The lowest feed costs per 1 kg of body weight gain were noted in the Hybrid Converter cross and amounted to 2.62 kg in females and 2.86 kg in males. In females, the feed conversion in the Hybrid Converter cross was lower by 0.07 kg or 2.7%; in males by 0.08 kg or 2.8%. Thus, a comparative assessment of the productive qualities of turkeys of two different crosses showed that the Hybrid Converter cross has a higher genetic potential for productivity, as well as high growth rates and its intensity.
