Abstract
The measurement of the nutritive value of pasture plants has become a subject of widespread interest, for the production and utilization of forage crops is of vital importance in the national system of agriculture. The measurement of pasture values, either by actual grazing with computation of the observed results into terms of digestible nutrients by the use of feeding standards in reverse, or by the quantitative collection of the forage and the computation of digestible nutrients by the use of assumed digestion coe~cients, is a procedure subject to severe criticism. A feeding standard is in part an expression of the judgment of its author as to the nutritive requirments of animals but is usually made liberal enough to include the con, tingencies of practice such as effects of climate, variation in quality of feeds, and in the digestive, assimilative, and m.etabolic individuality of the animals.
