Two-step weaning is used to wean off beef calves from their dams over the space of a couple of weeks. With this method the calf is fitted with a nose flap that prevents suckling for a period of time, after which the calf is separated from the dam preventing contact. The nose flap does not limit the calf from performing any behaviors other than suckling; they are still able to drink and graze normally. Most research has shown that this method reduces the amount of stress that the calves endure. Studies show that prior to separation there is no change in feeding habits, social interaction to other members of the herd. Once the nose flap is removed and the calves are separated from the dams, there has been data showing less vocalization, less pacing and spent more time eating than calves that were weaned on a more traditional method.
