pound heavier than the lambs dropped in Lot I. The second year's 

 results were practically the same excepting one ewe in Lot I aborted 

 about the middle of the feeding period. The probable cause of this 

 was injury received while weighing. During both years, more grain 

 was required to maintain the desired condition of the ewes receiving 

 corn stover than was required by the ewes receiving silage. 



The ewes receiving the stover refused about half of the roughness 

 given. The first year they were fed an average of 6.22 Ibs. of stover 

 per head per day and refused 2.39 Ibs. and the second year 5.97 Ibs. 

 stover was fed and 2.35 Ibs. refused. 



During the first year of this trial the ewes and lambs after lambing 

 were put on a ration of grain and alfalfa hay. The lambs from the 

 silage-fed ewes made a greater gain than the lambs from the ewes 

 fed on stover. During the second year when the ewes and lambs were 

 kept on the same ration that they received through the winter, the 

 lambs in Lot XI made the greater gain. The difference in the aver- 

 age daily gain made by the lambs was so small as to be of little signifi- 

 cance. From Table III it can be seen that with corn stover as a 

 roughness, from one-fourth to one-third more grain is required to 

 winter breeding ewes than when silage is used. Otherwise there 

 was little difference of practical consequence. It should be borne 

 in mind that the death of five ewes in Lot V was attributed to mouldy 

 silage. 



Corn Silage and Clover Hay vs. Corn Stover and Clover Hay. The 



object of this experiment was to secure data upon a number of com- 

 binations of roughnesses in order to determine so far as possible those 

 most desirable for Missouri conditions. Clover being a common 

 hay crop on all the better farms of the state, combinations of clover 

 and corn silage, and clover and corn stover were tested. The results 

 of this work is reported in Table IV.
