Why is colostrum particularly important for newborn mammals?

Colostrum is particularly important for newborn mammals because it contains essential antibodies and nutrients that are critical for the animal's health and immune system development. Immediately after birth, newborns are often unable to produce their own antibodies, making them vulnerable to infections and diseases. Colostrum, which is the first milk produced by mammals following birth, is rich in immunoglobulins (antibodies) that provide passive immunity by transferring protection from the mother to the offspring.

In addition to antibodies, colostrum is also packed with vital nutrients such as proteins, vitamins, and minerals that support the newborn's growth and development during a crucial early period of life. These components not only help in strengthening the immune system but also contribute to the overall health and well-being of the young animal as it adapts to life outside the womb.

While energy, digestion support, and hydration are important for newborns, the unique combination of antibodies and nutrients in colostrum addresses their immediate needs for immunity and nutrition more directly than the other options.
