A Study of “Flaky” Milk

Abstract

A condition characterized by the irregular appearance of tiny, elongated, tenacious floccules in the milk of certain cows is described. In the majority of instances the involved quarter presents little that is abnormal; in certain cases firm areas about the cistern and milk ducts were noted. The floccules characteristic of the condition are composed of masses of leucocytes and mucus. Organisms of the same types (non-hemolytic and hemolytic streptococci and hemolytic staphylococci) as those found in mastitis are present in the “flaky” milk. An increased number of leucocytes and a relatively high blood protein elimination are characteristic. The findings suggest a mild but prolonged mastitis. © 1927, American Dairy Science Association.
