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 $4.07. 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
