What is the significance of administering colostrum to newborn animals?

  1. It helps in digestion

  2. It provides hydration

  3. It contains essential enzymes

  4. It provides maternal antibodies

The correct answer is: It provides maternal antibodies

Administering colostrum to newborn animals is crucial because it provides maternal antibodies, which help to protect the young animal from infections and diseases in the early stages of life. Colostrum is the first milk produced by a mother after giving birth, and it is rich in immunoglobulins, specifically IgG, that play a vital role in the immune system. Newborns are born with an immature immune system and have little to no passive immunity of their own, making the transfer of antibodies from the mother essential for their health and survival. The timing of colostrum intake is also significant; newborns should consume it within the first few hours of life to ensure that the antibodies are effectively absorbed through their intestines. This early intake is necessary because the intestinal lining closes to the absorption of antibodies within the first 24 hours after birth. The other options do not emphasize the primary importance of colostrum effectively. While colostrum may aid in digestion and provide hydration, and it contains some enzymes, these are secondary to its critical function in providing maternal antibodies that form the foundation of the newborn's immune defense system.
