ANALYSES OF FEEDSTUFFS

The following table gives the analyses of a number of feedstuffs, showing the percentage of digestible nutrients and fertilizing constituents in each:

From the above table we find that five tons of alfalfa hay contains 1,100 pounds of protein, equal to this food element in

Cotton seed meal	2,956	pounds
Linseed meal	3,754	pounds
Wheat bran	9,016	pounds
Cowpea hay	10,185	pounds
Red clover hay	16,176	pounds
Timothy hay	39,285	pounds
