During the past few years exceedingly important discoveries have been made concerning the science and practice of live stock feeding. Further more, economic conditions have radically changed. Therefore, Professor Morrison has again entirely rewritten the book to include the latest information and to adapt it to the changed economic conditions since the World War. Just as in the previous revision, the results of many important investigations, completed so recently as not yet to be in print, have been furnished by scientists thruout the country, in order that the findings might be presented in this revision.
