Effect of Ration on the Development of Pigs

2. When corn was the sole source of protein in the ration, the ratio 
of protein stored to protein consumed was 1 to 7. This ratio was ob¬ 
tained when com was fed for a prolonged period—900 days. This agrees 
with the ratio obtained in several other instances when corn was fed for 
a period of 180 days. This appears to be the limit of the possibilities 
of protein storage from corn. 
3. The two pigs, one fed com and ash, the other fed corn and protien- 
free skim milk, stored 1 therm for 18.82 consumed during the first 
400 days of the experiment. During the last 500 days they stored 1 
therm for 3.19 consumed. The pig fed com alone stored 1 therm for 
8.23 consumed during the first 600 days. During the last 400 days he 
stored 1 therm for 2.93 consumed.
