TECHNOLOGICAL AND ECONOMIC ASPECTS OF INCREASING THE LEVEL OF REALIZATION GENETIC POTENTIAL IN BROILER CHICKENS’ PRODUCTIVITY

As a result of research conducted in the production conditions of LLC ProdMit and LLC POZTS Svezhenka, it was established that the level of realization of the genetic potential in compliance with the European Productivity Index (EPI) in broilers of the Ross 308 cross was equal to 85.2-87.1%, and in the Cobb 500 cross - 81.0-82.0%. The maximum yield of meat in body weight from 1 m² of floor space was obtained at a stocking density of 22.7 heads/m² - 50.8 kg, and the highest EPI was 461 units at a stocking density of 15.8 heads/m². Both crosses possess high meat qualities corresponding to the standards of modern industrial poultry farming. Morphological and biochemical parameters of the blood of the experimental chickens were within the physiological norm.
