World Dairy Expo 2026

World Dairy Expo 2026 took place September 29 through October 2 in Madison, Wisconsin.

A 2026 attendance figure is not given here; the 2025 edition drew an estimated 51,525 attendees from 83 countries. The event was billed as combining the world's largest dairy-focused Trade Show with a Dairy Cattle Show of the finest cattle in North America.

World Dairy Expo is held in Madison, Wisconsin, USA, with registration and exhibits centered on the Exhibition Hall.

World Dairy Expo draws international dairy trade professionals, with a dedicated networking space for companies and organizations that serve the international dairy market, entry to which required an international pin and ribbon. The show provided interpreters fluent in Chinese, French, German, Portuguese, Russian and Spanish for its international attendee base.

It is most useful for dairy producers, genetics and feed suppliers, and equipment buyers, since it combines a large dairy trade show with a cattle show, and the 2025 edition drew an estimated 51,525 attendees from 83 countries with 246 sponsors including John Deere, Zoetis and Merck Animal Health. Knowledge Nook sessions on herd health, feed efficiency and genetics from speakers at CRV, Alta Genetics and Vita Plus were billed as giving farmers practical content, and international visitors got interpreters and a dedicated space; those outside dairy, or who dislike crowds, would get little from it.

Dairy farmers and industry attendees usually wear jeans, work boots or sturdy shoes, and company caps or jackets, since much of the day is spent walking barns and a large exhibition hall. Early October in Madison can be cool, so a jacket or layers are sensible.
