What is the method used for removing feet on cows?

The correct method for removing the feet on cows involves removing the lower half of the leg at the knee or hock. This technique is generally preferred because it preserves more of the animal's body and allows for a cleaner surgical site. By removing the entire lower limb at the joint, rather than just the hoof or foot itself, the procedure facilitates better healing and reduces the risk of complications associated with infection or improper bone alignment.

When considering the other methods mentioned, cutting off at the ankle may not provide enough structural removal for effective healing. Pulling off the hoof does not address the underlying structural elements of the leg that may need attention or removal, and using a guillotine is not a standard practice in veterinary medicine for this purpose and could result in unnecessary trauma to the animal. Thus, the method focusing on the joint removal is both a well-established and animal welfare-conscious practice.
