Since 1944, the National Research Council, and now the National Academies of Sciences, Engineering and Medicine (NASEM), has published 11 editions of the Nutrient Requirements of Swine. As the primary reference for developing swine diets, the 12th edition will be a valued resource to feed industry members, their customers, swine nutritionists and researchers. The Institute for Feed Education and Research (IFEEDER), with the National Pork Board, National Corn Growers Association and United Soybean Board, is providing funds and industry feedback to support the revision.
