Which term describes a castrated male goat?

A castrated male goat is known as a wether. This term is specific to male goats that have been castrated, which is a common practice for various reasons, including behavior management, health, and to improve the quality of the meat. By removing the testicles, the male goat becomes less aggressive and more docile, making it easier to handle, especially in domestic settings.

The other choices represent different classifications of goats and sheep: a kid is a young goat, a buck refers to an intact male goat, and an ewe is a female sheep. Understanding these terms helps in the effective management and breeding of livestock, as they define the animal's gender and reproductive status.
