CHAPTER XVIII. 
MISCELLANEOUS INVESTIGATIONS. 
Ir 1s 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, in interpreting 
the results of livestock 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,” 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
