difference can be noted between poor and good feeder cattle, but sometimes even 

 a careful study of steers does not reveal tbeir feeding possibilities. An ad- 

 vance of 8 cts. per bushel in the price of corn increased the cost of gains $1 

 per 100 lbs. In the second experiment, where a ration of corn and alfalfa hay 

 was fed, an increase of 1 ct. per bushel in the price of corn had the same effect 

 in increasing the cost of gains as did an increase of $1 per ton in the price of 

 alfalfa hay."

 and F. G. King (Indiana Sta. Bui. 179 (1914). pp. 385-^0.4).— Continuing pre- 

 vious work (E. S. R., 30, p. 769), nine lots of 25 choice Idaho lambs, weighing 

 approximately 60 lbs. per head, were fed from November 14, 1913, to February 

 22, 1914, with the results shown in the following table : 



Summary of lamh feeding experiments. 



The addition of corn silage to a ration of shelled com and clover hay reduced 

 the hay consumption and slightly reduced the quantity of grain eaten and the 

 rate of gain made by the lambs. It also reduced the cost of gain 0.49 cts. per 

 pound, slightly increased the selling value of the lambs, and increased the profit 

 22 cts. per lamb. 



Lambs fed com silage as the only roughage or com silage and oat straw as 

 roughage had irregular appetites and required great care to prevent their going 

 " off feed." The addition of oat straw to a ration of shelled corn, cotton-seed 

 meal, and corn silage had no beneficial effect on the ration. The addition of 

 clover hay to a ration of shelled corn, cotton-seed meal, and corn silage produced 

 excellent appetites in the lambs, and greatly increased the quantity of feed 

 eaten and gains made by the lambs. 



The addition of cotton-seed meal to a ration of shelled corn, clover hay, and 

 corn silage increased the appetites of the lambs for both grain and hay and 

 increased the rate of gain. A grain mixture of seven parts com and one part 

 cotton-seed meal proved slightly more effective for producing rapid gains and 

 on less feed than a grain mixture of four parts corn and one part cotton-seed 

 meal.
