What term refers to the process of removing the testicles of male sheep?

The term that refers to the process of removing the testicles of male sheep is castration. Castration is a common practice in sheep management and is done for various reasons. One of the primary reasons for performing this procedure is to control breeding and improve the temperament of male sheep, making them easier to handle. Castration can also help prevent unwanted pregnancies and reduce aggressive behavior in males, which is especially important when managing a flock.

In contrast, docking refers to the removal of a portion of a sheep's tail and is typically done for health and hygiene reasons. Culling is the practice of removing animals from the breeding population based on certain criteria such as health, age, or production ability. Weaning refers to the process of separating lambs from their mothers, typically around the time they are ready to eat solid food. Each of these terms relates to sheep management but serves a different purpose. Thus, the correct answer—castration—specifically addresses the removal of the testicles in male sheep.
