PART II , : 



GROUND SOYBEANS vs. COTTONSEED MEAL FOR 

 FATTENING STEERS 



This trial is the third of a series to determine the comparative 

 value of ground soybeans and cottonseed meal as nitrogenous sup- 

 plements to rations for fattening cattle. Since it is a well established 

 fact that corn silage is most efficient as a feed for fattening cattle 

 when fed in connection with a concentrate containing a high per 

 cent, of protein, it is highly desirable that a source of native concen- 

 trated protein be available. Since ground soybeans contain the high- 

 est per cent, of protein of any of the native feeding products avail- 

 able in quantities large enough to be of great economic importance, 

 this series of trials was inaugurated to establish their value as a cattle 

 feed. The relative composition of ground soybeans and cottonseed 

 meal is shown in the following statement : 



The cattle fed in this trial are described on page 862. The 

 method of starting the cattle on feed is shown on page 864. In 

 previous trials rations under comparison have been identical except 

 as between cottonseed meal and ground soybeans. Other series of 

 trials, however, have shown that rations containing oat straw and 

 silage have practically the same effect on the cattle as rations con- 

 taining clover hay and silage. The trial reported in this bulletin was 

 made with the lot that received soybeans, receiving oat straw in 

 addition to silage as roughage, while the lot receiving cottonseed meal 

 received clover hay in addition to corn silage as roughage.
