A summary of this experiment shows that the feeding of corn 

 silage alone as a roughage was the more satisfactory of the two 

 methods of feeding. In this lot the gains were made more cheaply 

 and larger daily gains were obtained than were made by the cattle 

 receiving corn silage and hay for a roughage. The cost of produc- 

 ing one hundred pounds of gain was greater in Lot II than in Lot 

 I. This is, however, due to the fact that mixed hay is more ex- 

 pensive at $12.00 per ton than is corn silage at $3.50 per ton. 

 The experiment also bears out the results of previous experi- 

 ments at the Station, which indicate that when light weight 

 cattle of about 900 pounds are put on roughage during the early part 

 of the feeding period they will make economical gains even though 

 it may be done at smaller gains per head daily. 



The cost of producing one hundred pounds of gain in Lot I was 

 1.15 cents less than that of Lot II. This difference was in a meas- 

 ure due to the irregular gains made by Lot II and also the price 

 charged for hay. The necessary margin between the buying and 

 selling prices of the two lots was 47 cents in Lot I and 71 cents in 

 Lot II. The price received for each bushel of corn consumed after 

 paying the average market price for the other feeds was $1.469 for 

 Lot I, and $1.308 for Lot II. Allowing a proportionate increase in 

 value for all feeds fed from the profits on the cattle the returns are 

 as follows : 



Lot I. 



Corn Silage $ 5.69 per ton. 



Cottonseed Meal 49-79 per ton. 



Corn 891 1 per bushel. 



Lot II. 



Corn Silage $ 5.09 



Mixed Hay 17.45 



Cottonseed Meal 45.05 



Corn 799 per bushel. 



The hogs in Lot I gained 611 pounds while following the cattle. 

 In addition to the droppings from the steers, they received 2160 

 pounds of a grain mixture of corn and tankage. Valuing the addi- 

 tional feed at $25 per ton, they made a profit of $30.12 from follow- 

 ing the cattle. The hogs in Lot II gained 575 pounds. They also 

 received 2160 pounds of grain in addition to what they were able
