Cross-breeding is a fundamental tool of selection, allowing one to manage heredity and the variability of economically useful traits. For an agronomist and a practical poultry farmer, understanding the mechanisms of genetics is the basis for increasing productivity, whether it be obtaining high-quality livestock products or forming the biological foundation of a future harvest. Mastering these principles makes it possible to shift work with populations and cultivars from the category of random successes to the plane of predictable results.
This collection gathers materials covering the key aspects of the breeding process. Readers will find information here on the basics of genetics and the laws of heredity applied in the development of hybrids. We have paid attention to the classification of poultry by productivity types, detailed characteristics of egg-laying chicken breeds, and the basic principles of selecting source material for sowing. Studying the presented articles will help one understand how to correctly approach the issues of improving the quality indicators of poultry farming and crop production, relying on a scientific approach and modern breeding methods.
