Which of the following describes an uncastrated male goat?

A male goat that has not been castrated is referred to as a buck. This term is specifically used to identify mature male goats that retain their reproductive capability. Bucks play a vital role in breeding programs due to their ability to sire offspring. In contrast, the term "doe" is used for female goats, while a "kid" refers to a young goat, regardless of gender. The term "yearling" describes a goat that is between one and two years old but does not indicate the animal's reproductive status. Understanding these terms is essential in animal science, particularly in goat husbandry and breeding practices.
