When should newborns be fed colostrum?
It’s critical to feed newborns colostrum within a certain time frame. This is because the efficiency of absorption of immunoglobulins derived from colostrum declines after birth. “Intestinal closure” will happen when macromolecules are no longer released into the circulation. For example, in calves and lambs, closure takes place approximately when the animal is 24 hours old. Efficiency of absorption will decline from birth, especially after 12 hours.
