TABLE II. Value of Corn Silage With and Without Cured Rough- 

 age for Fattening Lambs, November 5, 1914 to 

 February 3, 1915 



and 



Table II shows that there was no difference in the grain coi 

 sumption between the lots receiving oat straw and corn silage, 

 clover hay and corn silage but that the lot receiving no dry rough- 

 age consumed slightly smaller quantities of grain. About half as 

 much oat straw was eaten in Lot 5 as clover hay in Lot 7. There 

 was a marked increase in the silage consumption when no dry 

 roughage was fed. The lambs receiving corn silage as the only 

 roughage gained 23 pounds in ninety days; those receiving oat 

 straw and corn silage as roughage gained 27 pounds, and those re- 

 ceiving clover hay and corn silage gained 30.1 pounds in ninety 

 days. The grain required to make a pound of gain was highest in 

 Lot i receiving no dry roughage and least in Lot 7 receiving clover 

 hay and corn silage as roughage. The silage required to make a 

 pound of gain was least in Lot 7 but in this lot it required 3.35 

 pounds of clover hay in addition to the grain and silage to make a 

 pound of gain, while in Lot 5 it required 1.82 pounds of oat straw 

 in addition to the silage. The cost of gain was $6.74 per hundred 

 weight in Lot I receiving no dry roughage, $6.21 per hundred weight 

 in Lot 5 receiving oat straw in addition to the corn silage and $7.37 

 per hundred weight in Lot 7 receiving clover hay in addition to the 

 corn silage. The addition of oat straw to the corn silage increased 

 the selling price of the lambs ten cents per hundred weight and the 

 addition of clover hay to corn silage increased the selling price of 

 the lambs 35 cents per hundred weight. The profit was 92 cents 

 per lamb in Lot I, $1.21 per lamb in Lot 5, and $1.15 per lamb in 

 Lot 7, thus showing that as an economical ration oat straw in ad- 

 dition to corn silage was more efficient than clover hay. This is 

 slightly contrary to results secured in the winter of 1913-14 in 

 which clover hay proved more economical than oat straw.
