Dairy at Guelph had great representation at ADSA 2020.

Here is the list of all the presentations made by members of Dairy at Guelph at that event. Links to some of the presentations will be made available in the near future.

The titles are organized in the same categories used in the official list of abstracts as seen in the J. of Dairy Science, Volume 103, Supplement 1.

This list shows not only the breadth and depth of dairy research done by U of Guelph scientists, but also some of their extensive national and international collaborations.
