idea of its feeding values. Only that portion of the feed
which can be digested and assimilated can in any way

purposes. The disposition of the energy values in feeds
is illustrated in the following table, constructed by H. P.
Armsbv and published     in the "'yclopedia of American
Agrict lture".
Energy per Hundred Pounds.
