SUMMARY STATEMENT. 
1. The objects of this test and the kinds of calves used were very 
similar to those of the previous test. 
2. The whole number of 46 calves was divided into three lots and 
fed from November 29, 1912, to March 3, 1913, the following rations : 
Lot 1. Cottonseed meal ; cottonseed hulls. 
Lot 2. Cottonseed meal, two-thirds; corn chop, one-third; cottonseed hulls; 
corn silage. 
Lot 3. Cottonseed meal ; cottonseed hulls ; corn silage. 
The supply of corn silage was exhausted by March 3, but the calves 
were not ready for the market, so on this date they were all thrown 
together as one lot and continued on : 
Cottonseed meal ; corn chop ; cottonseed hulls ; mixed hay. 
3. During the silage period (November 29 to March 3) an average 
daily gain of 1.49, 1.23, and 1.49 pounds was secured in lots 1, 2, and 
3, respectively. 
4. During the silage period (November 29 to March 3) it cost 
$5.59, $6.09, and $5.13 to make 100 pounds of increase in live weight 
in lots 1, 2, and 3, respectively. 
5. In the fall of 1912 the calves cost 4|- cents a pound. At the end 
of the silage period they were not ready to be sold and estimated 
values were placed upon each lot. The calves in lot 1 were valued at 
5^ cents a pound, and those in lots 2 and 3 at d\ cents a pound. 
6. Each calf during the silage period netted a clear profit of $2.70, 
$1.19. and $1.95 in lots 1, 2, and 3, respectively. 
7. By comparing lot 1 with lot 3 it is found that one ton of corn 
silage saved 1.161 pounds of cottonseed hulls. If cottonseed hulls 
cost $7 per ton, the corn silage, therefore, was worth $4.06 per ton 
for fattening these calves. 
8. This test clearly demonstrates that if corn is to replace part of 
a cottonseed meal ration, more than one pound of corn should be 
used to take the place of one pound of cottonseed meal. In other 
words, cottonseed meal has a greater feeding value, pound for pound, 
than shelled corn. 
9. After the supply of silage was exhausted the calves were all fed 
58 days longer on a ration composed of cottonseed meal, corn chop, 
cottonseed hulls, and mixed hay. They gained during this period 
only 1.09 pounds daily, but their value increased very materially, and 
at the end they sold for almost 7 cents a pound on the farm. 
10. For the entire period November 29 to April 29 each calf re- 
turned a clear profit of $6.27.
