Abstract

The purpose. To enrich economically beneficial attributes of meat-egg hens of domestic gene pool at crossing with genetic material of foreign selection. Methods. Selection-and-genetic, zootechnical, biometric, systemic approach, theoretical analysis and synthesis. Results. As a result of introduction of new genetic material of auk of foreign highly productive meat crosses «Kobb-500» and «Ross-308» into gene pool of meat-egg hens of local population their adaptive and productive attributes were improved, the level of variability that created good preconditions for increase of genetic potential and combinational variability of auk of domestic selection was raised. Conclusions. Expediency and perspective of use in the breeding purposes is proved of cocks of final hybrid of foreign meat cross «Ross-308» at their prolong use for improving indices of alive mass and egg production of meat-egg hens of domestic gene pool.
