12 BULLETIN 631, U. S. DEPARTMENT OF AGRICULTURE. 
As previously stated, hogs followed the calves that had a partial 
ration of corn-and-cob meal and received some benefit from the 
droppings. This item does not appear in the above financial state- 
ment, but it is discussed in a later paragraph. 
Leaving out of consideration for the present the results secured 
from the hogs, it is seen that the greatest profit was realized on the 
calves that were fed cottonseed meal, cottonseed hulls, and mixed 
alfalfa hay. It did not pay to feed the corn-and-cob meal along 
with the cottonseed meal at the prevailing prices of the two feeds, 
and the greater the proportion of corn used the smaller the resultant 
profits. In lot 1 each calf returned a clear profit of $5.40: but in 
lot 2. where one-third of the cottonseed meal was replaced by corn- 
and-cob meal, a profit of only $4.30 was made on each animal: and 
in lot 3, where two-thirds of the cottonseed meal was replaced by 
corn-and-cob meal, the profit per calf dropped to $1.07. All the 
profits, however, were satisfactory ; but, leaving out of consideration 
the profits derived from the hogs, the cottonseed meal ration proved 
to be the most profitable. 
HOGS FOLLOWING CALVES. 
It was thought that if hogs were allowed to follow the calves that 
ate a partial ration of corn-and-cob meal they would derive some 
benefit from the undigested corn in the droppings. In a former test 1 
an effort was made to get some benefit from the droppings when the 
steers ate nothing except cottonseed meal as the concentrate, but this 
ended in a failure, so no pigs were placed in lot 1. Eight pigs, 
averaging 87 pounds in weight, were placed in lot 2, and an equal 
number, averaging 89 pounds in weight, in lot 3. Of course, these 
pigs were not able to secure sufficient feed from the droppings alone 
to produce rapid gains, so the droppings were supplemented by corn. 
These pigs followed the calves throughout the test, and during the 
whole time those in lot 2 ate 3,715 pounds of shelled corn in addition 
to what undigested corn they secured from the droppings of the 
calves, but those in lot 3 ate only 2,953 pounds of corn. These feeds 
caused all the pigs to make rapid gains. Those in the second lot 
increased in weight 805 pounds, but the pigs in the third lot increased 
in weight only 689 pounds. 
Small profits were made on each one of the lots of pigs, and these 
profits should be credited to the calves, or at least added to the total 
profits made in lots 2 and 3. With corn valued at 70 cents a bushel and 
hogs selling at 7 cents a pound, the hogs in lot 2 and 3 returned final 
profits of $9.91 and $11.32, respectively. When these profits are added 
to those already secured upon the calves in these two lots, the total
