The concentrations of some hormones and growth factors in bovine and human colostrums: Short communication

This study compared different levels of certain hormones and growth factors between bovine and human colostrums. Colostrums were collected from seven Holstein cows and seven healthy humans. Prolactin, epidermal growth factor (EGF) and nerve growth factor (NGF) had higher levels in human colostrums over the 3 days. A higher level of platelet-derived growth factor (PDGF) was found in bovine colostrums on day three; estradiol had higher levels on day three in both human and bovine colostrums. To minimise the differences of active components’ concentrations between these two types of colostrums, prolactin, EGF and NGF should be considered for addition into bovine colostrum products.
