Supercow (dairy)

Supercow (or super cow) is a term used in the dairy industry to denote lines or individual animals that have superior milk production: that is, which produce more milk per day, or in some cases produce more fat per gallon of milk.

Until recently, supercows have been developed through selective breeding - either traditional breeding or, since the 1960s, artificial insemination. Now the term tends to be applied to cows that have been genetically altered or whose genome has been studied in order to improve breeding.
