For years, poultry scientists have faced the challenge of preserving farm poultry. It was especially
acute with the transfer of poultry farming to an industrial basis, which led to the creation of highly
productive specialized lines and crosses of poultry for the production of eggs and meat from limited
genetic material.
Genotype selection has advantages over traditional methods. It does not take into account the
variability of economic characteristics due to the external environment, making it possible to evaluate the
bird at an early age, regardless of gender, and ultimately increases the efficiency of breeding work.
This is confirmed by the results of scientific studies in which the following indicators are reflected:
egg weight, control laying of eggs for incubation; biological control during incubation; fertilization and
hatchability of eggs of the dynamics of live weight of young animals (from 1
to 7 weeks) and adult birds; preservation of poultry livestock; feed costs per unit of live weight.
This article presents the results of studies conducted to improve and create new genotypes of farm
animals on the ducks of crosses of the northern region of Kazakhstan, based on the use of the
achievements of DNA technologies in breeding showed genetic similarities and differences of the studied
crosses.
