The Stomach of the horse contains from 17 to 

 19 quarts. The small intestine is y^y^ feet long, 

 the large intestine 24I/2 feet long. 



An important feature of any food is digestibil- 

 ity. Crushing or steaming food does not increase 

 digestibility, neither does a keen appetite result- 

 ing from hard labor do so. Horses digest less of 

 a food than cows and sheep. The digestibility of 

 coarse fodder is not increased by the addition of 

 other feeds. The normal body retains only about 

 1% of the food passing into it each day. About 

 one-quarter of the daily waste from the body is 

 by respiration, about one-sixth as urine, the re- 

 mainder as solid excrement. 



The composition of the customary feeds is as
