DISTRIBUTION OF CALCIUM, MAGNESIUM, PHOSPHORUS, ZINC, MANGANESE, COPPER AND IRON BETWEEN THE SOLUBLE AND COLLOIDAL PHASES OF EWES AND GOATSMILK

This paper examines the distribution of main elements (calcium, magnes ium and phosphorus) and microelements (zinc, iron, manganese and coppe r) between the soluble and colloidal phases of ewe's and goat's milk. The percentages of calcium, magnesium and phosphorus were higher in th e soluble phase of goat's milk (32.8, 66.4 and 38.6% respectively) tha n in that of ewe's milk (20.8, 56 and 34.8% respectively). In both spe cies most of the zinc (91.6% in ewe and 87.5% in goat) and the mangane se (93% and 89% in ewe and goat respectively) were found in the micell ar fraction. The distribution of iron and copper differed more. The so luble phase of ewe's milk contained 28.5% iron and the soluble phase o f goat's milk 44.3%. Ewe's milk contained more soluble copper (33.3%) than did goat's milk (18.1%).
