is said to be dead. The animal body requires food, 

 water, and air, and when supplied with them it can 

 move about and do work. Take away any one of them, 

 and the body soon becomes unable to move, and dies. 

 182. How to Feed Animals. — The art of feeding 

 animals is knowing how to supply them with the proper 

 amounts and kinds of food. Different kinds of animals 

 of course require different amounts of food. A cow 

 or a steer can eat at one time much more food than a 

 horse, and a horse can eat more than a sheep. Then, 

 too, the same kind of animal under different conditions 

 requires different amounts of food. A working horse 

 requires more and better food than a horse that is 

 doing nothing. A cow giving milk requires more food 

 than a dry cow. To grow and feed animals successfully, 

 all these things must be considered. In feeding stock 

 one thing that should especially be considered is the 

 fact that scrubby animals eat just as much as fine, 

 well-bred stock. A cow giving 2 or 3 quarts of milk 

 a day will eat just about as much as a cow giving two 

 gallons. A cow giving an average of 3 quarts of milk 

 a day will produce in six months about 137 gallons, 

 which at 20 cents a gallon would be worth just $27.40. 

 A cow giving an average of 2 gallons of milk a day will 

 produce in the same length of time 365 gallons, which 

 at 20 cents would be worth $73.00. The food of each 

 is about equal in cost, yet the milk produced by the 

 better cow is worth $45.60 more than the milk produced 

 by the scrub. The scrub costs as much to feed as the 

 good cow and does less than half the work; she is, 

 therefore* more than twice as expensive to keep. A
