The authors studied productivity and product quality under industrial poultry production technology. The productivity of broiler chickens of Ross-308 and Hubbard Iza-F-15 was different during floor rearing. Broiler chickens of Ross-308 outperformed Iza-F-15 chickens in body weight and average daily gain. The live weight at the slaughter of Ross-308 chickens was 2,360 g. The live weight of the chickens of Iza-F-15 was 2088 g. The conversion of feed to produce was higher in the chickens of Ross-308 cross by 0,06 kg compared with the chickens of Iza-F-15 and amounted to 1.64 kg per 1 kg of live weight gain. The survival rate was high for Ross-308 chickens (95.8%). The safety of the flock of the Izu-F-15 chickens was 2.2 per cent lower and was 93.6 per cent. Slaughter yield in the chickens cross Ross-308 is higher than in the group of chickens cross Iza-F-15. Meat quality is also better in Ross-308 chickens. Growing broiler chickens of Ross-308 cross for meat under industrial technology allowed to get more profit compared to the use of poultry of Iza-F-15 cross. At the exact cost of feed, 1 kg of live weight gain was 7.1 roubles, and per 1 head of chick was 19.1 roubles. The profitability level is also 12.6% higher for the broiler chickens of Ross-308 cross. The cumulative indicator the European productivity index is higher for chickens of Ross-308 breed, compared with chickens of Iza-F-15 breed on 56 units. Thisindexwas 341 and 285, respectively .
