Why is a female reindeer called a cow?

In the context of reindeer and many other deer species, the term "cow" is used to refer to female animals. This terminology is rooted in agricultural language, where "cow" typically denotes the female of certain species, particularly livestock. Therefore, just as female cattle are called cows, female reindeer are referred to as cows, while males are called bulls. This terminology helps differentiate between the sexes in discussions about animal husbandry and wildlife management.
