In Ukraine, crosses of chickens imported from abroad are used for the production of food eggs. One of the world's leading breeding companies for egg chickens is “Hy-Line International”. The company's chicken crosses are widely used in poultry farms around the world, including in Ukraine. Hy-Line International offers the following chicken crosses to food egg producers using classical technology: "Hy-Line Brown”, “Hy-Line W-36”, “Hy-Line W-80”, “Hy-Line W-80 Plus”, “Hy-Line Silver Brown”, “Hy-Line Sonia” and “Hy-Line Pink”. The aim of the study was to analyse the latest trends in the breeding work of one of the world's leading breeding and genetic companies, Hy-Line International, and to characterise promising crosses for use in intensive poultry production, taking into account different consumer needs. It has been established that the fundamental importance for achieving high productivity of laying hens is strict adherence to the recommendations of “Hy-Line International” on the management of rearing of repair chickens for the industrial flock. It is necessary to pay attention to three critical periods in the rearing of young stock (from day-old to 6 weeks of age, from 7 to 12 weeks of age and from 13 to 17 weeks of age) and the compliance of the actual live weight of the hens with the recommended weight, depending on the cross. In a comparative aspect, the data on the live weight of repair chickens in different periods of their rearing and the safety of the livestock up to 17 weeks of age were analyzed. The indicators of egg production of chickens of different crosses depending on the period of their use, as well as the weight of eggs and Hau units, are presented, feed costs per unit of production are characterized, etc. In general, the research shows that “Hy-Line International” creates and works to improve egg crosses that can meet consumer demand for egg products according to their preferences.
