The 2021 Annual Meeting of the American Dairy Science Association® (ADSA®) will be held as hybrid meeting with a virtual component and a corresponding in-person meeting in Louisville, Kentucky, and will again be the most comprehensive dairy science meeting in the world. As a global forum for professionals, educators, and students, the meeting will attract more than dairy foods and dairy production specialists from more than 50 countries with common but diverse interests in the future of dairy science.

The in-person registration fee includes the Opening Reception, coffee and pastries during morning poster sessions, afternoon ice cream breaks in the exhibit hall, our always-popular ice cream social, a meeting with really nice people, and the best dairy science you will find in the world!

NEW IN 2021!

A hybrid meeting:  we are planning our first ever hybrid annual meeting. This means that while we plan to meet in person in Louisville, we will also have a robust virtual program available for those who can’t join us in person.

A co-located meeting:  In 2021, we are meeting in the same physical location as the American Society of Animal Science (ASAS), just prior to the ASAS Annual Meeting. There will be an overlap day of shared programming with ASAS on the final day of the ADSA Annual Meeting, along with a shared reception Wednesday evening.

An extended meeting: ADSA 2021 has been extended to a full day on Wednesday, with no increase in the registration rate. Be sure to plan your stay through Wednesday, including events on Wednesday night.
