What is colostrum?

Colostrum is the first form of milk produced by mammals immediately following the birth of a young one. It is a thick, yellowish substance that is incredibly rich in proteins, antibodies, and essential nutrients, making it particularly beneficial for newborns. This early breast milk is tailored to meet the needs of infants during their first few days of life, providing vital immune system support and promoting healthy growth and development.

Colostrum is crucial because it contains higher levels of immunoglobulins compared to later breast milk, which helps to protect the newborn from infections and maladies. Its high-calorie content also ensures that the newborn receives adequate nourishment right after birth when their digestive systems are still maturing. The unique composition of colostrum distinguishes it from other types of milk and is a key reason why exclusive breastfeeding is encouraged during the early days following delivery.

Other options reference different concepts: solid food is inappropriate for infants at this stage, malnutrition denotes a lack of essential nutrients and isn't related to colostrum, and child-rearing customs do not pertain to the biological aspects of milk production. This context emphasizes the nutritional and immunological importance of colostrum for newborns.
