LESSON XXVII 



FEEDS AND FEEDING 



Purposes of feeding. We have learned that we feed 

 live stock to repair the waste in their bodies, to make 

 them grow, to keep their bodies warm, to furnish energy 

 for work, and to make special products milk, eggs, wool, 

 and the like. All animals wear out their muscles by work 

 and exercise, and must have food to repair this waste or 

 they will grow thin and poor. The harder the horses 

 work, the more they must be fed. Young animals that 

 are growing must not only eat to repair the waste, but 

 they must have food to make them grow larger. The 

 bodies of animals are kept warm by the food they eat. 

 The strength of the horse and its power to do work must 

 come from the food it eats. The food builds up the mus- 

 cles, and strong muscles are necessary for work. Just 

 as the fuel and water make the engine go, so food fur- 

 nishes the heat and energy to ' ' make the mare go. ' ' In 

 addition to all these reasons for food, the dairy cow must 

 have food out of which to make milk. When the pasture 

 gets "short" in the summer, we notice the milk supply 

 runs low. So, too, the sheep must have an extra supply 

 of food out of which to make wool, and the hen requires 

 special food from which to make eggs. 



Kinds of food needed. Farm animals are a sort of 

 factory, producing materials that we need. The horse
