Abstract
THE author‘s primary object has been to show how rations for any class of livestock may be constructed by the use of the Kellner starch equivalent system and protein equivalents as measures for energy and protein requirements, and this object he has achieved in a smooth and satisfying manner. Like other books on the scientific feeding of farm animals, this volume conforms to the usual pattern, a preliminary explanation of the theoretical bases of scientific rationing being followed by a general description of feeding stuffs in common use, while in the latter chapters the principles of the rationing and management of the various classes of farm livestock are clearly and simply expounded. Following the experimental results of American investigators, the author has based the maintenance requirements for energy on the three-fourths power of the live-weight of the animal instead of on the usual surface law, and has also applied the same principle to the protein requirement estimations.
