Extract

There is considerable confusion in some lactation studies as to the meaning of the term milk yield. Furthermore, the various fractions of milk yield are ill defined. This note proposes a standardization of terminology on this subject. The problem is general and applies to all mammals. We will discuss it, however, in terms of the dairy sheep, the animal with which we are most familiar.
