Cow names are important features on the dairy farm. It makes it easy to say "Doctor, Belle has a sore on her leg", instead of saying "Cow X has a sore on her leg, no I mean the other Cow X". We also attempt to try to name in a series so we can quickly recall who is the calf of whom. In much the same way a horse farm might combine names of mare and sire of elite racing horses.
Having said this, I'd like to introduce two new calves on the farm. Gladys's daughter Gladiola, and Peanut's daughter, Snickers. Welcome to the farm little ladies!
