What is the primary role of colostrum for newborn animals?

Colostrum plays a critical role for newborn animals, primarily by supplying essential nutrients and antibodies. After birth, the immune system of newborns is immature and vulnerable. Colostrum is produced by the mother in the first few days after giving birth and contains a high concentration of immunoglobulins, which are antibodies that provide passive immunity to the newborn. This immunity is crucial as it helps protect against infections and diseases during the early stages of life when the newborn's own immunological defenses are not fully developed.

In addition to antibodies, colostrum is rich in vital nutrients, including proteins, fats, vitamins, and minerals, which are essential for growth and development. This nutrient content helps to jumpstart the newborn's health and supports their physiological processes as they transition to a regular diet. Thus, the combination of essential nutrients and antibodies makes colostrum a cornerstone for the survival and health of newborn animals.
