Bottle feeding promotes rapid and efficient absorption of antibodies from colostrum. Feeding colostrum with a nursing bottle stimulates esophageal-grove closure. The esophageal groove shunts the colostrum from the calf’s mouth and esophagus past the rumen directly into the abomasum. Curds form and antibodies contained in the whey promptly go into the small intestine where they are absorbed.
