This table assumes the corn to be worth $ .45 per bushel, cotton- 

 seed meal $30 per ton, hay $10 per ton, corn stover $4 per ton and 

 corn silage $2.50 per ton. The prices given for corn and cottonseed 

 meal are what they actually cost as they were bought for feeding these 

 steers. The prices given for the roughage is estimated. From this 

 table it is seen that the feed eaten by Lot I cost $103.73, while that 

 eaten by Lot II cost $109.91, making a difference in cost of $6.18 to 

 offset the difference in gain of 155 pounds. Assuming that the steers 

 sold at five and a half cents a pound, the 155 pounds was worth $8.53. 



This does not represent the actual difference between the two 

 feeds as Lot II at the close was in better condition and would proba- 

 bly have sold somewhat higher on a discriminating market. Had the 

 silage been normal throughout the entire experiment, undoubtedly 

 the difference in favor of Lot II would have been even greater. 



Undoubtedly a part of the superior value of the corn silage was 

 due to the ears which it contained as it is noted that on this feed the 

 steers ate a smaller amount of grain than those fed corn stover. 

 BARN VS. SHED-FIFTH TRIAL. 



During the winter of 1906-07 a further test was made similar to 

 those made during the past four winters reported in Bulletins 64 and 

 68 and in the annual reports of 1902-03 to 1905-06 inclusive. The ob- 

 ject of this trial was to secure further data on the relative economy of 

 barn and shed as shelter for fattening steers in Pennsylvania. The 

 same quarters were used as heretofore, viz : A large pen or box stall 

 in the basement of the College barn for one lot, and an open shed in a 

 yard adjoining for the other. This shed is situated south of the barn, 

 is open toward the scuth-east but closed on the back and two ends. A 

 part of the yard including that beneath the shed, has been paved with 

 cinders so that it is possible for the steers to keep out of the mud. An 

 effort was made to keep each lot well bedded so that the steers might 

 have a comfortable place to lie down when they felt like it. 



As in former years the four main points observed were as follows: 



i st. Comparative gain in live weight. 



2nd. Amount of feed eaten. 



3rd. Relative amount of feed required per pound of gain. 



4th. Relation of temperature to gain.
