132 RESULTS OF EXPERIMENTS IN SWINE FEEDING 
tendency to produce more fat in the body of a hog than would 
feeds which contain a higher percentage of protein and ash. 
Without going into details, it may be said that corn was fed 
in opposition to mixtures containing such feeds as dried blood, 
wheat middlings, peas, skim-milk, bran, and cow-peas, which 
are feeds much richer than corn in protein. 
Results—The methods employed in the investigation 
varied somewhat, but the general results were as follows: 
1. The pigs fed the protein-rich ration generally dressed 
a somewhat lower percentage of their live weight than those 
fed the corn ration. 
2. In nearly every case the pigs fed the protein-rich ration 
had the largest quantity of blood, and in every case they had 
heavier livers than the others. Their kidneys were also heavier, 
as a rule, though there were some exceptions. 
3. In the Wisconsin and Kansas experiments, the tender- 
loin muscles were removed and weighed, and in both cases 
these were heavier in the case of the protein-fed pigs. The 
tenderloin muscle is am indication of the amount of lean 
throughout the carcass, and hence it was demonstrated that 
the carcasses of the protein-fed pigs contained more lean than 
the others. 
4, As a rule, the corn-fed pigs gave more leaf-lard than the 
others. 
5. At the Wisconsin and Kansas stations, the breaking 
strength of the thigh-bones was tested by a machine designed 
for such purposes, and in every case the bones from the pigs 
fed the mixed ration proved stronger than those of the corn-fed 
pigs, the difference being as high as 32 per cent in one trial. 
Limitations—Though the experiments described demon- 
strate very clearly that it is possible to modify the carcass of 
the pig by a judicious selection of feeds, we must not assume
