CHAPTER XVIII. 



MISCELLANEOUS INVESTIGATIONS. 



IT is out of the question to review in detail all the work 

 of experiment stations in swine feeding, but there are certain 

 phases of the work which may be dealt with profitably in a 

 somewhat general way. The problems which face the swine 

 feeder are numerous, and the experiment stations have been 

 working for years to find solutions for some of them. To 

 solve any problem in stock feeding is a tedious matter, because 

 animals differ so much individually in their ability to utilize 

 feed, and it requires many repetitions and the employment of 

 large numbers of animals to answer an apparently simple 

 question. Great care is necessary, therefore, hi interpreting 

 the results of live-stock experiments, and it will not do to 

 draw general conclusions where only a limited amount of work 

 has been done. 



INFLUENCE OF FEED UPON THE BODY OF THE PIG. 



In his excellent book, " Feeds and Feeding/ 7 Professor 

 Henry gives an account of work done along this line by 

 Sanborn at the Missouri Agricultural College, Henry at the 

 Wisconsin Experiment Station, Shelton in Kansas, Duggar 

 in Alabama, and Fortier in France. 



Corn, which is the standard hog feed of the United States, 

 is a feed rich in carbohydrates, or fat-forming constituents, 

 but rather low in protein, or muscle-forming constituents. It 

 is also low in ash, or bone-forming material. The question 

 arose, therefore, whether a feed such as corn would not have a
