Key Technical Points for Natural Mating Breeding of White-Feathered Broiler Chickens
(1) Male-to-female ratio The male-to-female ratio refers to the number of hens each rooster is responsible for mating. Taking free-range floor rearing as an example, the male-to-female ratio for fast-growing white-feathered broilers is 1:8-10, for high-quality white-feathered broilers it is 1:9-12, and for layer-type chickens it is 1:10-13. If raised on wire-floor flat rearing, the lower limit should be adopted;
