What's in a name?

Research just out from England's Newcastle University suggests that if you want your cow to give more milk, you have to give her a name. Cows with names like Daisy, Gertrude or Buttercup give more milk - up to 284 litres a year more - than no-name cows. While calling for "the personal touch", the study does not say if the actual name itself eg Bruiser, Pig-Face or Jericho could influence milk production (or not).
