Let's test our agriculture math skills with a little dairy industry story problem:
If an 8-ounce glass of whole milk provides 149 calories, 8 grams of protein, 276 milligrams of calcium, 8 grams of fat, 4.5 grams of saturated fat and 24 milligrams of cholesterol, and a cup of two-percent milk has 120 calories, 5 grams of fat, 3 grams of saturated fat and 20 milligrams of cholesterol, what kind of music will result in an overall milk production increase of 3%?
According to a study at the University of Leicester School of Psychology, the answer is slow jams and easy listening.
Actually, research shows that bovine musical preference, like that of aerobics instructors, hinges less on any specific artist than on beats per minute.
...I hope they didn't spend too much on this study. Upon reflection, isn't it just common sense that noise-sensitive herd animals attached to machines via their udders would choose a mellow groove over death metal or psychobilly?
(Poor Bananarama. It must've stung when the University of Leicester's team told the world that 1,000 Holstein Friesian cattle liked listening to nothing at all better than their 1986 Billboard Hot 100 #1 hit, "Venus.")
To paraphrase another 80's fave, I know what cows like, thanks to a panel of five Holsteins who got to pick the winner of the British Columbia Dairy Association's 2012 “Music Makes More Milk” contest. Brace yourself:
Did anyone else just imagine a thousand cows with phones to their ears, chewing their cuds and swishing their tails, content to remain on hold indefinitely?
Should the above tune ever grow old (doubtful) there's always Shakespeare. According to NPR, a theatrical reading of “The Merry Wives of Windsor" proved popular, milk-wise, with an audience of UK cows. And Modern Farmer has honored Lou Reed by including one of his compositions (no, not "Metal Machine Music, Part 1") in their recent Playlist To Milk By:
"Everybody Hurts," REM
"What a Difference A Day Makes," Aretha Franklin
"Bridge Over Troubled Water," Simon & Garfunkel
"Moon River," Danny Williams
"Orinoco Flow," Celtic Woman
