To conduct a comparative assessment of the morphometric parameters of chicken embryos of egg crosses with different egg shell color during the incubation period

The relevance of the research In the incubation of poultry eggs, many specific features that open up great opportunities in managing the process of breeding birds. The incubation regimes are developed and continue to improve on the basis of the patterns of embryonic development of birds. At the present stage, zootechnical science has achieved significant success in improving the breeding, feeding and maintenance of agricultural poultry, which has formed highly productive and highly profitable poultry farming in the conditions of highly profitable poultry farming, the most important is the issue of improving technological parameters and improving product quality at all stages of production. The incubation of poultry eggs has many specific features that open up great opportunities in managing the reproduction process of birds. The incubation regimes are developed and continue to improve on the basis of the patterns of embryonic development of birds. Currently, in industrial poultry farming, the average value of hatching chickens is 80-85%. And this is on condition that all hatching eggs are pre-selected on the basis of external signs and egg mass. This means that in the industrial poultry industry, the assessment of hatching eggs, increasing hatchability, viability of young animals during artificial incubation does not lose its relevance .The purpose of the study is to conduct a comparative assessment of the morphometric parameters of embryos of chickens of egg crosses with different egg shell color during the incubation period.
