Calf managers need to provide the immunoglobulins and nutritional support necessary to not only keep calves alive but also to achieve growth as soon as possible after they are born. A reasonable management goal should be to have less than 5% mortality in the calf barn. Most calves will lose some weight during their first two weeks of life.
