Feeding Ensilage to Lambs. 341 



It will be observed from Tables I and II that the gain of these 

 two lots of lambs was very uniform, and that the total gain was 

 praeticaliy the same, so that any deductions we may draw from 

 the experiment will come from comparing the cost of food con- 

 sumed by the two lots, rather than any marked difference in 

 growth or wei^t. 



By referring to Tables III and IV it is seen that the total 

 amount of dry matter consumed by the two lots was practically 

 the same, while the amount of water drank or consumed varies 

 considerably. The lot fed wholly on dry food drank 555 pounds 

 more wajter during the exiperiment, than did the lot fed ensilage, 

 while the total water consumed in food and drink by the ensilage 

 fed lot was 324 pounds more than that consumed by the lot fed 

 wholly on dry food. By the water consumed is meant not only 

 the water drank but the water contained in the food as well. This 

 is found in the third column of Tables III and TV. 



As the grain ration fed these two lots as well as their grain was 

 practically the same, it may be seen from Tables HI and TV that 

 the ensilage seemed to take the place of a part of the hay. Lot I 

 ate 1,1G6 pounds of ensilage and 606 pounds of hay, Lot n ate no 

 ensilage and 906 pounds of hay, therefore, the 1,166 pounds of 

 ensilage took the place of 300 pounds of hay or about four pounds 

 of ensilage to one of hay. As a matter of economy the ensilage 

 was a cheaper food than the hay m this experiment; since the 

 cost of 1,166 pounds of ensilage is much less than the cost of 300 

 pounds of hay. To carry the comparison still further, assuming 

 as a basis a yield of two tons of hay per acre, would require as an 

 equivalent a yield of less than eight tons of ensilage per acre. As 

 a matter of fact our land that produces two tons of hay yields 

 from twelve to sixteen tons of ensilage per acre. Or the com- 

 parison may be made in stUl another way, if hay costs ten dollars 

 per ton the ensilage in this experoment had a feediug value of 

 more than two and one-half dollars per ton. 



Nitrogenous and Carbonaceous Rations for Lambs. 

 From, a flock of twenty-seven grade Shropshire lambs, about 

 eight months old, eighteen were selected for experimental feeding 

 and divided into two lots of nine each. Although quite thin in
