In this study, protein and salt distributions in the milk of 48 Holstein-Friesian cows were studied. Gross composition samples variation between individual was line with expectation. However, mineralisation casein fraction, expressed mmol protein-associated calcium per 10 g casein, differed >2-fold samples. Reasons for are unknown could not be correlated to and/or genetic variants caseins. Furt...
