Lot A received no feed in addition to the pasture as one 

 object was to learn whether it would pay to supplement the 

 pasture with a concentrate. During the summer of 1908 

 each steer in Lot B was given daily 3.31 pounds of cotton- 

 seed cake in addition to the pasture: in 1909 each steer in 

 this lot was fed 3.4 pounds of the cake per day in addition 

 to the pasture. In 1908 "Caddo" cake was used in one lot 

 so that its value as a feed could be compared to cottonseed 

 cake. The steers in Lot D in 1908 (these were a mixed 

 bunch of steers and cannot be compared directly to the other 

 three lots) , on account of being smaller than the ones in the 

 other lots, were fed only 2.76 pounds of cottonseed cake per 

 head per day. In 1909 cottonseed was fed to Lot E.

 Average daily gain of each steer 2.32 pounds. 

 Cost of 100 pounds of gain .... $2.56 

 Total profit per steer 10.42 



tonseed cake was more efficient than the "Caddo" cake for 

 making gains. In 1908 only 143 pounds of cottonseed cake 

 were required to make one hundred pounds gain, while 180 

 pounds of the "Caddo" cake were required to make the same 

 number of pounds gain. Lot D cannot be compared to Lots 

 B and C. It is true that the "Caddo" cake did not cost as 

 much as did the cottonseed cake, but it will be seen later, 

 when the cost of the feeds are taken into consideration, that 

 ^he cottonseed cake was the more economical feed to use. 

 Cinder the conditions of this test one pound of cottonseed 

 cake was equal, in feeding value, to 1.28 pounds of "Caddo" 

 cake.
