Table I shows that the addition of corn silage to a ration of 

 shelled corn and clover hay had no effect on the grain consumption 

 but that 112 pounds of silage replaced 65 pounds of clover hay in 

 roughage consumption. The gains made by the lambs were so near- 

 ly the same in the two lots that the difference is negligible. In 

 economy of gain the lambs fed corn silage showed a saving of 81 

 cents on each hundred pounds of gain, 452 pounds of corn silage re- 

 placing 283 pounds of hay and 1.2 pounds of corn. The selling value 

 of the lambs was slightly increased by the use of corn silage as is 

 shown by the selling price of the two lots of lambs. When corn 

 and clover hay were fed the average profit per lamb was $1.02 as 

 compared with $1.41 by the lambs fed corn, clover hay and corn 

 silage. 



PART II 



CORN SILAGE ALONE VS. CORN SILAGE AND DRY 

 ROUGHAGE FOR FATTENING LAMBS 



Part II is a discussion of results in which corn silage was fed 

 as the only roughage for fattening lambs as compared with oat 

 straw and corn silage, and clover hay and corn silage. All lots of 

 lambs in this discussion received a grain ration consisting of seven 

 parts of shelled corn and one part of cottonseed meal. Lot I re- 

 ceived corn silage alone as roughage after the first fourteen days. 

 Owing to the fact that the lambs did not take readily to silage as 

 the only roughage, it was necessary to give some clover hay during 

 the first two weeks on feed. After this time, however, the lambs 

 were limited to corn silage as roughage, except at one time after 

 they had been on feed for eighty days, it was necessary to give one 

 feed of clover hay to bring the lambs back onto feed. The lambs 

 receiving no clover hay did not consume as much silage as in 

 former years. The maximum consumption of silage was 54 pounds 

 daily for twenty-five lambs. The maximum grain consumption in 

 Lot i was 28 pounds daily for twenty-five lambs. In Lot 5 re- 

 ceiving oat straw and corn silage there was a maximum silage con- 

 sumption of 34 pounds daily for twenty-five lambs. In Lot 6 re- 

 ceiving clover hay the maximum silage consumption was 30 pounds 

 to twenty-five lambs. The lambs in Lots I and 5 receiving no clover 

 hay were more difficult to keep eating well than the lambs in Lot 7 

 receiving clover hay and corn silage. At the end of eighty days on 

 feed the lambs in Lot I went off feed badly and it was necessary 

 to reduce their ration very materially and give them one feed of 

 clover hay in order to get them to eating well again.
