Culling is the process of selection of surplus animals from an animal population. In a wild population the selection is often done by destroying the animal immediately, in a domesticated situation the culling process involves selection and the selling of surplus stock. The selection may be done to improve breeding stock, for example for improved production of eggs or milk, or simply to control the group's population for the benefit of the environment and other species.
