Informal nutrition symposium: Overview of the nutrient requirements of poultry, 10th revised edition

Abstract

The most recent (9th) edition of the National Research Council’s “Nutrient Requirement of Poultry” report was published in 1994. A new edition of this report is being prepared for release in 2025, by the National Academies of Science, Engineering and Medicine (NASEM). The 10th edition of the Nutrient Requirements of Poultry publication is substantially updated in terms of the volume of information included, reflecting the goal to serve a more educational purpose than previous reports. Wherever possible, nutrient requirement values have been updated to reflect the most current research. However, for many of the individual nutrients, little work has been done to determine the requirements of modern poultry strains. A preview of the updated NASEM report was presented during the Informal Nutrition Symposium at the 2024 Annual Meeting of the Poultry Science Association. Topics included overviews of each chapter, as well as identification of the substantial research gaps for most nutrients, and a discussion of the use and need for mathematical models to allow for prediction of nutrient requirements of the ever-changing genetics of commercial poultry.
