The smaller the fat globulesthe longer time is required for the cream to rise. In themilk of certain breeds of cows the fat globules are verysmall; such milk does not cream well. In rich milks,containing over four and one-half per cent of fat, the fatglobules are larger and creaming is rapid and complete(36).
