What term is used to describe the action of removing an undesirable rabbit from the herd?

The term "cull" is specifically used in animal husbandry, including rabbit breeding, to describe the process of removing an undesirable rabbit from the herd. This practice is essential for maintaining the health and quality of a breeding program. Culling is typically based on factors such as health issues, poor conformation, undesirable temperament, or failing to meet breed standards. The goal is to enhance the overall quality of the animals that remain in the herd, thereby improving breeding outcomes and ensuring that only the strongest and best specimens contribute to future generations.

In contrast, the other terms don't capture the specific concept of culling in livestock management. "Dispose," for instance, implies simply getting rid of something without any connotation of the selective process involved. "Retire" suggests that an animal is being withdrawn from breeding, but not necessarily removed from the herd. "Delete" is more commonly associated with digital information and does not pertain to animal management. Therefore, culling is the most accurate term in this context.
