What's In A Cow's Name?

I read a little blurb that I found interesting and I thought I'd share it with you.  It appears that a couple of veterinarians in the United Kingdom have won an award for their study on dairy cows.  Their study found that cows that are given names actually produce more milk, when you use their name regularily.  They found that cows are very responsive when handled by caring, friendly owners that call them by name, to the tune of 258 liters per year.  Now I don't think naming your livestock is so meaningles as I had thought.
