It’s no secret that the fertility and egg hatchability of a broiler breeder flock decrease as birds age. But in recent years, there has been a broader, overall decline.
Adding fishmeal into the diets of broiler breeder roosters could improve egg hatchability, North Carolina State University research suggests.
A drop in USDA’s broiler chicken hatchability rates from 85% to less than 80% in the past decade runs counter to the poultry industry’s improvements in production efficiency, but making just a small improvement in hatchability can create significant economic benefits.
