Gabriela Cardoso, Ph.D. – Novus International

The U.S. poultry industry is currently facing challenges with breeder production and hatchability. In recent years, hatchability has been lower than 82%, the worst numbers since 1988 (Agristats report 2023). Some have blamed poor fertility or embryo mortality, but the root cause of this widespread phenomenon is unclear.

To add to this challenge, the industry has also reported an increase in progeny mortality. Despite these challenges, other regions like Europe, Asia, and Latin America, do not report or do not have the same performance decline.

Producing healthy chickens is the base of the broiler industry and vital to the food supply chain. This symposium will bring experts from around the world to share their experiences and help identify probable causes for these challenges and offer possible solutions.
