Feeds; Animal nutrition. 52 FEEDS AND FEEDING, ABRIDGED ever, the greater part of the food is required merely as fuel to keep up the body temperature. Hence, except for the pig, maintenance rations for the larger farm animals may consist largely of cheap roughages, such as hay and straw, which furnish abundant heat but do not yield much net energy. This has great practical importance, for it shows why idle horses and stock cattle can be carried thru the winter on roughage alone, without grain. It is commonly assumed in computing rations that the amount of feed required to maintain an animal depends on its body Pig. 14.—Heavily-fed Animals Oedinaeily Have an Excess of Heat Heavily-fed fattening steers thrive best with no shelter except an open shed, but animals being carried thru the winter on scanty rations need warmer quar- ters. (From Prairie Farmer.) Strictly speaking, however, the maintenance requirement depends not on the live weight, but on the body surface. This is due to the fact that the loss of heat from the body is proportional to the body sur- face and not to its weight. A 1,600-lb. steer does not have twice the body surface of an 800-lb. one, and hence will not require twice as much feed for maintenance. Individual animals of the same kind and size may also differ somewhat in their requirements. For example, a quiet animal uses up less body fuel than a nervous, active one. Due chiefly to increased muscular action, an animal when stand-.
