Composition of the Milks of Dairy Cattle. II. Ash, Calcium, Magnesium, and Phosphorus

Abstract
Milks from commercial dairy herds in Southeastern Pennsylvania were analyzed for ash, Ca, Mg and P. Milk samples were from single milkings of 151 healthy purebred cows in midlactation. The data represent market milk composition. Average values for all animals were ash .78%, Ca 1.25 g/l, Mg .11 g/l and P 1.14 g/l. The data also were grouped and analyzed by breed and .beta.-lactoglobulin phenotype. Breeds differed in all inorganic components with 18-33 cows/breed. No differences in ash, Ca, Mg or P were significant when the data were grouped by .beta.-lactoglobulin phenotype.
