Feeds; Animal nutrition. FEEDING AND CARE OF HORSES 223 only one-fourth as much, and more energy is actually spent in digesting and masticating wheat straw than it supplies. Hence, it has a negative value for producing work, tho it may aid in keeping a horse warm. Carrots yield but a small amount of work per pound, due to their watery nature. It is clear from this table that the harder a horse works, the greater must be the proportion of concentrates, such as corn, and oats, in his ration, and the smaller the proportion of roughages, as hay and straw. Types of work performed by the horse.—It is evident that the horse at work must receive a larger supply of nutrients than when idle, and that the amount needed will depend on the severity of the work done. Let us then consider what types of work the horse per- forms. His work usually con- sists of a more or less complex combination of the following simple kinds: (1) Locomotion, or traveling along a level course without a load; (2) raising the body, with or with- out a load, against the force of gravity in ascending a grade; (3) carrying a load; (4) draft, or hauling a load. A horse drawing a load up a hill combines all of these types. He is (1) advancing and at the same time (2) raising his body. Likewise, he is (3) carrying the harness and (4) hauling the load. In descending the hill the horse will be called upon to perform even a fifth type of labor, brac- ing himself to prevent too rapid a descent. The amount of nutrients required in each of these types of work has been determined in careful experiments. However, the results are of theoretical rather than practical interest, for the work of most horses varies greatly from day to day and is usually of a complex nature, difficult to divide into these simple types.
