or an average daily gain per calf of 1.49 pounds. The calves of lot 
2, averaging 633 pounds, gained 102 pounds, or 1.52 pounds per head 
per day. These gains were not large, but it must be remembered 
that the calves had been on feed some time before being put in diy 
lot. They fattened much more rapidly than the gains would indi- 
cate, and at the end of the feeding period were quite fat.

The calves of lot 1 consumed 299 pounds of cottonseed meal and 
2.460 pounds of silage for each 100 pounds of gain in weight, while 
those of lot 2 consumed 195 pounds of cottonseed meal, 391 pounds 
of corn, and 1,900 pounds of silage to make the same amount of gain. 
Each 100 pounds of gain cost $9.82 and $12.44 for lots 1 and 2, 
respectively. The calves receiving cottonseed meal as the sole con- 
centrate consumed 560 pounds more silage for each 100 pounds of 
gain in weight, but they consumed so much less concentrated ration 
that the gains cost almost 3 cents a pound less.
