144 PIG'S STOMACH. 



Near the intestinal opening, which is guarded by a mus- 

 cular ring, hence called the pylorus, is a lesser pouch, called 

 the antrum pylori 



The convex margin, c, is called the greater curvature, and 

 the concave one is the lesser. Along the first is situated the 

 spleen, and the pyloric end is connected with the posterior 

 surface of the liver. 



The horse's stomach is remarkable for its smallness in con- 

 trast with the size of the intestine, and of the body generally. 

 The average capacity does not exceed from 14 to 15 quarts. 

 A horse dying from indigestion, with repletion of the 

 stomach, has not more than from 20 to 30 Ibs. weight of 

 food in it. By accustoming the animal to very bulky soft 

 meat, the stomach becomes very large and very thin, 

 whereas the natural size of the organ is preserved when 

 horses are fed on sound dry fodder. These facts should 

 not escape the attention of all who have to direct the feeding 

 of horses. 



The stomach of the pig (see Fig. 75) is larger in proportion
