Abstract
Studies have been conducted on the spiking of 170–day-old male breeders to hens in order to improve the quality of incubation eggs of meat chickens of the Ross-308 cross. The effectiveness of late spiking of roosters to female breeders has been proved and the most significant factors determining the fertility of poultry in different communities have been identified. For the first time, methods have been developed for recruiting and maintaining a parent flock of egg chickens, providing them with comfortable conditions and contributing to an increase in egg fertilization by 3.0%, and the percentage of hatchability by 3.2%.
