ISSUE FOCUS 44 FEED & ADDITIVE MAGAZINE February 2026 Elvor Immune can be administered as a complete or partial replacement of the colostrum: its dosage must be calculated according to quality and quantity of the colostrum. It should be fed within the first two hours of life to maximize immunoglobulin absorption. Farmers can reconstitute the appropriate dosage in warm water or in the mother’s colostrum: it guarantees the newborn receives essential systemic protection and local intestinal defence, regardless of maternal colostrum quality. Elvor App can help to check colostrum quality and to give the recommended Elvor Immune dosage. In summary, colostrum management is the foundation of a dairy herd's future productivity. Strict adherence to the 5Qs, supported by precision tools and innovative solutions like Elvor Immune, transforms a major health risk into a powerful lever for sustainable herd performance. A calf requires the biological foundation of colostrum to reach its full genetic potential. References 1Sockett et al., 2023.
