Abstract
Colostrum serves a special function in order to enhance the resistance of the newborn to infectious disease. This is shown by the high concs. of immune lactoglobulins in the colostrum. These lactoglobulins pass from the intestinal tract of the calf to its blood stream where they may persist for many mos. The immune lactoglobulins of bovine milk and colostrum, and the [gamma]- and T-globulins of bovine serum, have been isolated and compared with respect to their physical and chemical properties.
