Question

Which of the following is the primary role of colostrum in the newborn?

Options

• Sustained growth and development over 6 months

• Passive immunity and nourishment

• Brain development through fatty acid supplementation

• Bone development through mineral fortification

Answer 1

Colostrum's primary role is to provide passive immunity and initial nourishment to the newborn. The very high concentration of IgA antibodies in colostrum transfers crucial passive immunity, protecting the infant during the critical early days while their own immune system develops. It also provides essential nourishment through its high protein and nutrient density.
