Helping with event

New to World Dairy Expo, the FFA Dairy Forage Quiz was organized and conducted by the U.S. Dairy Forage Research Center in conjunction with the World Forage Analysis Superbowl.

FFA students were given a chance to answer questions relating to the dairy and forage industry to win an ice cream cone sponsored by Mycogen Seeds. Organizers estimate 800 FFA students took the quiz, and they look forward to holding the event again next year.

Can you pass the quiz? Test your knowledge with the questions below (answers are at the bottom of the page, but no cheating!).

Post a comment to tell us how many you got right – we’ll hold a drawing for a newly-designed Progressive Forage Grower hat from all those that participate (no matter how many you get right) by posting your results as a comment before November 28, 2011.
