Auburn Research Points to New Insights for Broiler Breeders
For poultry producers across the Southeast, new research suggests improving chick output may depend as much on how a flock functions together as it does on the individual birds themselves.
A study funded by USPOULTRY and the USPOULTRY Foundation, led by Dr. Charlene Hanlon at Auburn University, examined how group size, mating systems, male spiking and body weight variation affect commercial broiler breeder flocks. Researchers found smaller groups produced more eggs, larger groups achieved higher fertility, and introducing additional males, known as male spiking, improved reproductive outcomes.
But one finding stood out. Traditional measures of reproductive capacity were poor predictors of fertility and age-related declines. Instead, researchers found flock social dynamics emerged as a key driver of reproductive success, particularly female reproductive performance.
The researchers say that highlights an important and often overlooked piece of flock management. As scientists continue learning more about how birds interact within a flock, producers may have new opportunities to improve fertility, hatchability and overall chick output.
