A study done in 2001 on English cows found that when cows were played songs while being milked, the speed of the music affected how much milk was being produced. Specifically, the cows liked slow jams. Fast songs at over 120 beats per second (bps) caused milk production to drop. But slow songs that were under 100 bps increased production by 3% per day.Listen to Dominguez in the clip below:
