What is the term for a castrated male sheep?

The term for a castrated male sheep is "wether." This is a specific term used in sheep husbandry to describe males that have been castrated, which typically occurs to manage their behavior and require less resource-intensive care compared to intact males, especially in flocks where breeding is not the primary focus.

In contrast, "gelding" refers to a castrated male horse, while "barrow" is the term used for a castrated male pig. "Steer" is used when referring to a castrated male cattle. Each of these terms is specific to the type of livestock, highlighting the importance of proper terminology within animal husbandry practices. Hence, "wether" is the appropriate choice for a castrated male sheep.
