Learn the latest information in dairy nutrition and management by attending the virtual 2021 Four-State Dairy Nutrition and Management Conference on June 9-10. The new format is designed to improve the participant experience.

June 9 and 10 will feature live morning sessions designed to promote interaction and discussion between participants and the speakers. All presentations will be pre-recorded and will be made available to participants for viewing before the conference and for 60 days after the conference. General sessions will also have a live component with speakers providing a 5-minute live summary of their recorded presentation. This will be followed with a 45 minute to one hour question and discussion period between session speakers and participants. We encourage participants to watch the recorded presentation before the conference and come with your questions.
