Cows that are given names produce more milk than those that are not, says a new study out of England.

The study, conducted by Catherine Douglas and Peter Rowlinson at Newcastle University in Newcastle upon Tyne, discovered that more affectionate treatment of cattle — including giving cows names — can increase milk production by more than 68 gallons annually. An average cow produces about 2,000 gallons of milk a year.
