What is a sexually mature female of the ovine species called?

A sexually mature female of the ovine species is referred to as an ewe. This term specifically describes female sheep that have reached reproductive maturity, which typically occurs around 6 to 12 months of age, depending on the breed and individual factors.

In contrast, the other terms represent sexually mature females of different species. A gilt is a female pig that has not yet given birth; a hen is a sexually mature female chicken; and a filly is a young female horse that is under four years of age. Thus, understanding these definitions is essential for correctly identifying the terminology used in animal husbandry and veterinary science.
