corn. The seventh day feeding means that on every seventh day milk 
protein or milk casein from 3 pounds of milk was fed for each pound of 
com and on six days corn alone was fed. The ash-free blood protein 
was fed in such amounts as to give a nutritive ratio approximating 1 to 4. 
The black blood albumen was fed in such amounts as to make a nutri¬ 
tive ratio very nearly 1 to 5. Alfalfa pasture was the sole feed of the 
pigs in two lots. One representative pig from each of the latter lots 
was slaughtered when taken off the alfalfa pasture. After being taken 
off the pasture the pigs were fed com alone. Milk albumin from 3 pounds 
of milk for each pound of corn was fed to lot 17 in experiment IV. In 
experiment V, lot 26, the albumin was fed in such amounts as to furnish 
an amount of protein nearly equivalent to the casein in 3 pounds of milk 
for each pound of corn. The former is designated as small amounts and 
the latter as large amounts. The com germ was fed in the proportion 
of 1 pound of germ to 2 pounds of corn. The com was fed in the form of 
meal, and the supplementary feeds were mixed with this meal. 
AMOUNTS CONSUMED 
The amounts of the several chemical constituents in the various feeds 
consumed by the different pigs during these trials are given in Table I. 
It should be noted that the data refer to only one pig from each lot.
