48 BULLETIN 631, U. S. DEPARTMENT OF AGRICULTURE. 
SUMMARY. 
1. Short-aged calves that are too young to wean and put on feed 
in the fall can be fed grain while on pasture the following summer 
and sold directly off grass or finished in the dry lot. 
2. During both the summer and the winter feeding periods the 
calves that were fed shelled corn and cottonseed meal made larger but 
more expensive gains than those fed on cottonseed meal as the sole 
concentrate. 
3. Gains made during the summer are very much cheaper than 
those made in the dry lot during the winter. 
4. The grain ration of the calves of lot 1 cost $9.50 and that for 
lot 2, $16.08 for the summer. 
5. The calves cost $5 per 100 pounds in the spring and the cost in 
the fall after all feed and pasture was charged against them was 
$5.02 and $5.73 per hundredweight for lots 1 and 2, respectively. 
6. When on full feed, each calf of lot 1 ate 4-J pounds of cottonseed 
cake per day ; and of lot 2, 3 pounds cottonseed cake and 6 pounds of 
shelled corn. 
7. The calves were fed 179 days on pasture and 67 days in the dry 
lot, or a total of 246 days. 
8. The calves of lot 2, which received shelled corn, were much 
fatter than those of lot 1 when finished and they dressed out 2 per 
cent more. They also sold for 43 cents more per hundredweight. 
9. Eight pigs following the calves of lot 2 made one pound per 
head per day gain and returned a pork credit per calf of $2.65. 
10. When the pork credit is considered the calves fed corn re- 
turned almost the same profit as the calves fed cottonseed meal. 
11. For each calf of lot 2 to make the same profit as lot 1. namely, 
$10 per head, the corn had to be charged at 77 cents per bushel 
instead of 80 cents. 
VI. GENERAL DISCUSSION OF THE FIVE YEARS' EXPERI- 
MENTS. 
The prices of the feeds and cattle used varied so much from year 
to year that the financial statements of the various experiments are 
not strictly comparable. If cottonseed meal was very cheap one year 
and comparatively high another year, the financial outcome of the 
two experiments would be misleading. This is true of all similar 
experiments, and for this reason experimental data can not be used 
directlj 7 by a feeder where conditions are different from those re- 
ported in the experiment. 
If the farmer is given certain data as to the average daily gains, 
the amount of feed required to make 100 pounds of gain, and if he
