What role does lighting play in broiler breeder farming?

For broiler breeder roosters, lighting has no significant effect before 19 weeks of age, but after 20 weeks of age lighting has a great influence, especially when the temperature is suitable, as it can improve semen quality and the roosters' libido. For broiler breeders, extending the lighting duration during the rearing period can advance sexual maturity, and the age at first egg is earlier, but the hatching eggs are small and the laying period is shorter. If the lighting duration is gradually reduced during the rearing period, sexual maturity can be delayed. Therefore, proper lighting control can increase the egg production of broiler breeders. However, lighting must also be closely coordinated with the quality and quantity of feed, the calcium supply, and the rearing week age or laying rate, so that they work together to increase the egg production of broiler breeders.
