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 Xovember 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 htdls 

 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 (Xovember 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 (Xovember 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-J 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 h\ 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 com 

 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 perio 

 only 1.09 pounds daily, but their value increased very materially, an 

 at the end they sold for almost 7 cents a pound on the farm. 



10. For the entire period Xovember 29 to April 29 each calf re- 

 turned a clear profit of $6.27.
