Colostrum is the pre-milk produced by mammals after giving birth. Bovine colostrum is specifically from bovines, including cows. This early life nutrition is very yellow in color, colostrum is also known as “liquid gold” due to high beta-carotene content. Colostrum is thicker than regular milk and packed with vitamins, minerals, and bioactive nutrients that help develop a healthy immune system and gastrointestinal tract (the gut).
Like human babies, calves are not born with a fully developed immune system, so it’s vital that they get the colostrum they need to survive and thrive. Growth factors, immunoglobulins, bioactive proteins (such as proline-rich polypeptides), bovine milk oligosaccharides, antibodies, and more, are found to be especially rich in bovine colostrum.
