Comprehensive assessment of breeding value of poultry
The article is devoted to the actual problem - a comprehensive assessment of breeding value of poultry. To further increase the production ofpoultry products, increasing productivity, viability, and growth of quality indicators of poultry are of decisive importance. In order to create competitive breeds and crosses of poultry in our country, measures are being taken to improve the organization of breeding business by forming a system of specialized, well-technically equipped breeding and genetic centers, breeding plants and reproductive farms, which are closely interrelated in functional and quantitative terms with each other and with commodity enterprises. A promising direction in improving breeding business, preserving the gene pool of valuable, highly productive breeds, increasing productive and reproductive qualities is an objective comprehensive assessment of breeding value of poultry bred in the country (bonita-tion). Comprehensive assessment of breeding qualities of poultry (bonitation) is carried out in all poultry farms with breeding herds: sgts, poultry-breeding farms, reproducers of I and II orders, farms - reproducers and poultry farms in the presence of parent herds. The purpose of bonitation is an assessment of productive qualities of birds and the division into classes according to breeding value. Poultry is evaluated by main and additional features. At the same time, the bird of baselines, parent and parent forms is evaluated separately. Application of developed standards will increase productive and reproductive qualities of breeding and commercial birds by 3-5% due to objective assessment and selection of breeding birds in breeding centers, breeding plants and reproductive farms.
