Colostro como fonte imunológica e nutricional na criação de bezerras de aptidão leiteira

Abstract

Facing the absence of transplacental transfer of immunoglobulins to the bovine newborn, the primary objective of this review was to address the colostrum relevance as an immunological source and care needed to perform an adequate colostrum intake. Aiming at the maximum absorption of maternal immunoglobulins, we highlight the maintenance of a colostrum bank in dairy farms, focusing in providing high quality colostrum, in adequate quantity and at the right time after birth. Also, the use of surplus colostrum and transition milk in the form of silage is discussed, being it a restricted nutritional alternative for dairy calves, compared to others, such as whole milk and milk replacers.
