Dear Colleagues,

The International Symposium on Ruminant Physiology (ISRP) has for decades been the world's leading ruminant nutrition and physiology conference. We are delighted to be hosting the meeting back in the United States and are excited to invite you to join us for cutting edge presentations and discussion in Chicago in August of 2024. No city represents the United States more proudly than Chicago, the heart of America's heartland.

The ISRP meeting only occurs every five years and consistently provides an unrivaled array of presentations and insightful discussion with the largest group of international ruminant physiologist gathered in one place. The four-day program will be built around top-notch invited presentations complemented with selected short original research presentations and posters during breaks. The topics will broadly span ruminant physiology from feeding behavior and rumen fermentation to post-absorptive intermediary metabolism and physiological and metabolic regulation. The meeting is traditionally attended by the top ruminant nutrition and physiology researchers, practitioners, and enthusiasts from across the world and there truly is something for everyone at the conference.

Chicago is an ideal location to assemble an international meeting for both convenience of air travel and interesting activities. In addition to the scientific program, there will be many opportunities for you to socialize with conference participants while exploring the iconic architecture, historic museums, award winning restaurants, and professional sports teams that make the Windy City a top tourist destination. Post-conference excursions will also provide the opportunity to see the agricultural bounty of the Midwest and the beauty of the Great-Lakes in addition to historical Chicago sites.

The ISRP meeting is considered a "can't miss" event by many and we promise that the 2024 will not disappoint! The 2024 organizing committee, in being supported from the American Dairy Science Association Foundation, is looking forward to welcoming you to Chicago to join the discussion and enjoy the American Midwest.
