Final answer:
Colostrum is the early milk produced by mammals after birth, packed with immunoglobulins for immune defense, and provides crucial nutrients for newborns. It helps with immune system boosting, and digestive system development, and provides hydration and nutrition.
Step-by-step explanation:
Colostrum is the first form of milk produced by the mammary glands of mammals immediately following delivery of the newborn. Most notably in humans, it is secreted during the first 48-72 hours postpartum, providing approximately 3 ounces in 24 hours. Although this seems like a small volume, it is highly concentrated and sufficient for the newborn in the first few days of life. Colostrum is rich in immunoglobulins, which are essential for conferring gastrointestinal and systemic immunity to the newborn as it adjusts to a nonsterile environment.
Here are three benefits of colostrum for a newborn:
- It provides critical immune defenses by introducing immunoglobulins which protect against infections.
- Colostrum aids in the newborn's digestive system development, helping to expel meconium and clear bilirubin.
- It supplies vital nutrients and hydration during the initial days post-birth, before the transition to mature breast milk.
