The Improvement of Quality in Milk Through the Efforts of College Extension Service

Dairy Department, Cornell University, Ithaca, New York

ABSTRACT

To be most effective, agricultural extension service must solve the vital problems confronting the rural public. Methods leading to the solution of the various problems will necessarily vary because of different circumstances, but their ultimate effectiveness is measured by the extent to which agricultural practices are changed. Extension projects which yield results that can be measured and expressed in definite terms, carry greater weight than projects which do not lend themselves readily to measurement.

Certain types of extension projects are by nature more easily demonstrated than are others. Variety tests, and the influence of different fertilizers, are excellent illustrations of projects that yield results which may be tabulated or which may even be visible to the eye. This is, true only to a limited extent with reference to milk problems. It is easily possible to demonstrate the amounts of manufactured products made from milk of varying compositions, or to show the influence upon the temperature of different methods of cooling; but it is difficult to satisfactorily demonstrate such an abstract thing as quality in milk, except in research.
