Conference Objective

The National Academies of Sciences, Engineering, and Medicine (NASEM, previously known as NRC) anticipates the 2021 release of the 8th revised edition of the “Nutrient Requirements of Dairy Cattle”, the world’s most highly cited reference on dairy cattle feeding. This Discover Conference® will focus on the scientific advancements in dairy cattle feeding used in revising the 2001 edition. They will report on areas with significant knowledge gaps that still prevent more accurate prediction of the nutrient requirements. We will emphasize the interactive spirit of Discover conferences® with structured small group discussions woven into the program, including a demonstration of the software and focused discussions with the speakers. The program will bridge from the fundamental science to applied dairy cattle feeding.

Members of the dairy science community interested in nutrient requirements of dairy cows. This includes researchers, extension specialists and consultants from academia, feed and crop industry technical specialists, veterinarians and animal health representatives, government agencies, and allied industries. Graduate Students and early career professionals are especially encouraged to attend.
