The importance of milk for the growth and health of a newborn offspring is well known. Milk contains immunoglobulin G (Ig G), Ig A, lactoperoxidase, lactoferin, cytokines, and growth factors. Osteopontin, one of the multifunctional proteins, is secreted by macrophages, T cell, and epithelial cells. Although osteopontin production in bovine milk have been documented, the precise expression levels in bovine milk have not been clarified. The aim of this study was to observe the expression of osteopontin, in bovine milk during the lactation period or bovine mammary glands.
