The Tri-State Dairy Nutrition Conference is an annual program organized collaboratively by personnel at The Ohio State University, Michigan State University, and Purdue University and the allied dairy industry. The objectives of the Conference are to disseminate current information on the feeding of dairy cattle primarily to individuals who provide nutritional advice to dairy farmers. Therefore, the audience consists of feed industry personnel, nutrition consultants, Extension personnel, students, and veterinarians.

Due to COVID-19, the Conference was cancelled in 2020 and due to the continuance of the pandemic, the 2021 Conference will be held virtually.
