In 2001, psychologists at the University of Leicester (UK) played fast music and slow music to 2 different groups of cows. The cows that heard fast music demonstrated no change in milk production. But the cows that listened to slow music increased their milk output by 3%.
Some dairy farmers agree with this assessment and play music for their cows. To promote the practice, the British Columbia Dairy Association is holding a contest which asks participants to submit playlists of good milk production music.
