TABLE II. Value of Corn Silage With and Without Dry Roughage 

 for Fattening Lambs, October. 28, 1915 to February 5, 1916 



Table II shows that the elimination of dry roughage from the 

 ration caused a decrease in the grain consumption by the lambs. 

 There was a very decided increase in the silage consumption due to 

 the elimination of the dry roughage but not an increase in the pro- 

 portion of the dry matter taken from the ration by the 

 elimination of clover hay. There was also a decrease in the gain 

 per lamb by the elimination of clover hay. .When clover hay was 

 fed there was a gain of 25.2 pounds per lamb during the feeding 

 period. When oat straw was fed in connection with corn silage 

 each lamb gained 17.2 pounds, whereas when corn silage was the only 

 roughage, there was a gain of 17.5 pounds. The cheapest gains were 

 made when the lambs received both corn silage and clover hay, the 

 cost being $8.26 per hundred pounds which covered the cost of 400 

 pounds of corn, 465 pounds of hay, and 445 pounds of silage. When 

 no clover hay was fed except during the first few days the cost of 

 gain was $8.86 per hundred pounds and the feed required to make 

 a pound of gain was 5.48 pounds of grain, .58 pound of hay and 

 10.77 pounds of silage. When oat straw was fed in connection with 

 silage more corn was required to make a pound of gain than when 

 either corn silage or corn silage and clover hay were fed and in 

 addition each pound of gain required 3.63 pounds of oat straw and 

 7.37 pounds of corn silage which made the cost of gain $9.11 per 

 hundred pounds. The finish on the lambs was very much better 

 when clover hay was fed in addition to corn silage, Lot 7 being 

 valued at $10.90 per hundred pounds in the lots as compared with 

 $10.05 m Lot i and $9.65 in Lot 5. The profit per lamb was $1.74 

 when both clover hay and corn silage were fed, 80 cents when corn 

 silage alone was used for roughage and 46 cents when corn silage 

 and oat straw comprised the roughage eaten.
