DOMESTIC ANIMALS 183 



Live stock of various kinds consume the coarser foods, 

 like the grasses, hays,, and grains, which man cannot use. 

 As a result of this consumption they store in their bodies 

 the exact substances required for the building up of the 

 tissues of man's body. 



When the animal is used by man for food, one class of 

 foods stored away in the animal body produces muscle ; 

 another produces fat, heat, and energy. The food fur- 

 nished by the slaughter of animals seems necessary to the 

 full development of man. It is true that the flesh of an 

 animal will not support human life as long as would the 

 grain that the animal ate while growing, but it is also true 

 that animal food does not require so much of man's force 

 to digest it. Hence by the use of meat a part of man's 

 life struggle is forced upon the lower animal. 



When men feed grain to stock, they receive in return power 

 and food in their most available forms. Men strengthen 

 the animal that they themselves may be strengthened. 

 One of the great questions, then, for the stock grower's 

 consideration is how to make the least amount of food fed 

 to animals produce the most power and flesh.

 horses were first tamed and used is not definitely known. 

 It is believed that they were first used for warfare and then 

 gradually bred and adapted to other purposes. 



Where food was abundant and nutritious and climate 

 mild and healthful, the early horses developed large frames
