Monitoring the quality of incubation eggs of meat crosses of imported and domestic production

The incubation eggs of the Cobb 500 cross (Hendrix Genetics), Ross 308 cross (Aviagen®), “Smena 9” cross from the All-Russian Scientific Research and Technological Institute of Poultry Farming were monitored. The physico-chemical parameters and physico-mechanical properties of the shell were evaluated and differences in the mineral composition were revealed: macro-, micro-, ultramicroelements. Morphometric and physico-chemical constants of the incubation egg contents have been established. The content of the main biologically active substances and the mineral composition of protein and yolk were compared. A method for evaluating an incubation egg is proposed for predicting hatch rates based on the principal component method and ranking ranges. Information has been obtained, the use of which significantly increases the efficiency of productive incubation indicators in meat poultry farming with specified parameters of egg fertilization productivity of 95–96.5%, with the hatching of chickens from 75 to 85%. 23–24 indicators reflecting the physical, mechanical, chemical, morphometric and weight indicators of incubation eggs are identified. It is recommended to use approximate reference values of quality indicators for specified productivity parameters. It is proposed to grade incubation eggs into four grades (AA, A, B, C) and rank them into four ranks (I, II, III, IV). The best option in terms of productivity is AA rank, a more significant indicator is I, a less significant rank is IV.
