Good news for the animal lovers among us--British researchers find that cows with names give more milk. (Hat Tip: Freakonomics). It's the sort of warm idea which pleases everyone--images of farmers stroking the cow's nose, before sitting down to milk her. Actually, I suspect it's an artifact: dairies with lots of cows can't give names, dairies with few cows can. And the only way a small dairy can survive is to pick the most productive cows.
Then again, sometimes animals earn names. (I wonder whether the piglets in this story got named, other than the expletives I'm sure Stonehead surpressed in writing it.) Which all reminds me of a cow we had named "Battleaxe". As one might expect, she didn't have a pleasant personality, nor was she particularly productive, but dad endured her for a few years, years which saw him educate his son in profanity.
