Cattle

Cattle were domesticated creatures native to Earth. The females were known as Cows and the males were known as Bulls. They were killed by humans for their meat and hide, and used to produce milk.

The Fourth Doctor asked some cows if they had a time scanner, but concluded that they didn't know anything about it. (DW: Image of the Fendahl)

As Earth's influence spread, cattle were shipped off the planet to across the Galaxy, such as Jadea. (EDA: Placebo Effect)
