The U.S. broiler industry is currently facing challenges in breeder production and hatchability. Hatchability rates have recently dropped below 82 %, the lowest since 1988 (Agristats Report, 2023), alongside increased mortality in pullets, breeder hens, and roosters. To address these issues, this symposium brought together global experts to share insights and strategies. Discussions focused on breeder nutrition, management, incubation management, and epigenetic effects on progeny. While primarily targeting broiler breeders, the symposium also explored practices in layer breeders to offer additional insights. A panel of five experts presented innovative ideas to enhance breeder performance and chick quality. Emphasis was placed on revising amino acid and energy requirements for modern genetics, optimizing management practices, and leveraging epigenetics to improve sustainability and performance. Hatchery practices were also identified as crucial for increasing hatchability and chick quality. For layer breeders, the focus extends beyond egg production to maximizing chick quality and viability through lighting, feeding programs, and genetic selection.
