What is the term for a female sheep?

The term for a female sheep is indeed "ewe." In sheep husbandry, ewes are important as they are typically the females kept for breeding and wool production. This distinction is critical in animal agriculture, particularly in the context of sheep breeds and their management.

A "filly" is a term used for a young female horse, not applicable to sheep at all. Similarly, a "heifer" is a young female cattle that has not yet borne a calf, showcasing the variety of terminology across different livestock species. Understanding these terms is essential for anyone studying animal science or working in agricultural settings.
