East Friesian

Sheep

The East Friesian is a breed of dairy sheep originating from East Frisia in northern Germany. It is either the best or one of the best sheep breeds in terms of milk yield per ewe. In physical appearance the East Friesians have pink noses and their head and legs are clear of wool. Their heads are naturally polled, i.e. hornless. They generally have pale hooves. The most distinctive feature of an East Friesian is its tail, which is described as a "rat-tail" because it is thin and free of wool.
