conditions and to supply the market demand, various 

 types of swine are produced. In general, the corn belt of 

 the United States, where an abundance of corn is pro- 

 duced and not very much other feed, is pre-eminently 

 adapted to the production of the fat or lard hog. Corn is 

 a carbonaceous feed, one that will produce fat and energy 

 principally, and will naturally make a hog that has a 

 greater proportion of lard. It is true that a hog cannot 

 develop at all if it is fed nothing but carbohydrate, but 

 corn has a little protein or muscle-forming ingredients, 

 and consequently will allow a hog to develop the lean 

 meat part of his carcass to a slight extent, especially if 

 corn is fed in connection with some other feed, even 

 though it be only grass. But with the preponderance of 

 fat-forming ingredients in corn, the hog will naturally 

 develop this part of its carcass excessively. 



Outside of the corn belt where corn is less abundant, 

 and other feeds are more abundant, more protein will be 

 supplied as well as more exercise, and the conditions are 

 more favorable to the production of bacon hogs. Feeds 

 other than corn usually have more protein ; furthermore, 

 they are not so concentrated, — that is, do not have quite 

 so much digestible nutrients per given bulk of feed. 

 Such conditions will allow the lean meat, or the protein 

 part of the carcass, to develop relatively more and the fat 

 part of the carcass relatively less. For immediate results, 

 however, a breed should be selected that will furnish the 

 type of hog desired by the breeder. 



LOCATION. 



In organizing a swine farm and in selecting a breed, 

 the location should be taken into consideration. The 

 adaptability of the country for swine production is a
