Table V shows the cost of the feed eaten by the two lots. From 

 this it is seen that the total cost of feed for Lot I, in the barn, was 

 $147.57, while the cost of that eaten by Lot II, in the shed, was $155.- 

 70. The figures for the cottonseed meal and corn represent the actual 

 cost of these feeds. The prices of hay and stover are estimated and 

 represent approximately what these products would have brought. 

 The cost of 100 pounds of gain on Lot I $8.57, while on Lot II it was 

 $8.15, showing greater economy in the outside lot. 



Table VI. General Summary of Five Years. 





Table VI gives a general summary of five years' work along this 

 line. From this table it will be seen that the daily gain per steer and 

 the estimated cost of a pound of gain are practically the same for the 

 two lots. During the last two years the showing has been more in fa- 

 vor of the shed on account of the yard being in better condition. 



COTTONSEED MEAL VS. AJ4X FLAKES FOR FATTENING 



STEERS. 



The object of this experiment was to compare the relative merits 

 of cottonseed meal and Ajax flakes as a source of protein for fattening 

 steers, as indicated by gain in live weight, cost of feed consumed, cost 

 of feed per pound of gain, and health and appetite of the animal. 



PLAN OF EXPERIMENT. 



December 18, 1906, two lots of twelve steers each as nearly equal 

 as possible were selected from two carloads bought in Pittsburg for 

 fattening at the College barn. 



The experiment began January i5th, 1907, and extended to 

 March 26th, a total period of seventy days. The lot known as Lot I 

 in this article is the same as Lot I in the shelter experiment described 

 elsewhere in this bulletin. The steers were fed grain in equal portions 

 twice daily. The amount of grain fed being dependent upon the appe- 

 tite of the animal. For roughage they were fed mixed hay in the
