Part I. 



Winter Fattening of Steers on Cottonseed 



Meal, Cottonseed Hulls, Corn Silage, 



and Johnson-Grass Hay. 



INTKOnLCTION. 



Cottonseed iiicnl and ('(dlonseed tudls, the two feeds 

 which in the past have hi'cn used almost exclusively dur- 

 ing the winter months lor. fattening cattle in the Soutli. 

 have advanced in ])ric(' very materially during the last 

 three or four yt-ars. This advancement in i)rice has 

 forced the southern farmers to seek feeds with which to 

 supplement the cottonseed meal and hulls. In tiie ex- 

 periment here reported silage ;iiid Johnson-grass hay 

 were used as sii|tpl(^mentary feeds to llic hulls. Cotton 

 seed meal was the only concentrated feed employed. 



Since the inauguration of the cooperative beef work 

 between the Alahanux Experiment Station and the Bureau 

 of Animal Tiuhislry, some results have been published 

 relative to winter fattening of steers,* but silage and 

 Johnson-grass hay were not introduced into any of the 

 former rations. It should be imderstood that this bulle- 

 tin is only a report of the progress of the cooperative 

 beef work, as the experiments are being continued. 



OBJECT OF THE EXPERIMENT. 



This ex])eriment was planned with the following ob- 

 jects in view: 



1 To determine the profd, if any, in fattening a good 

 grade of cattle in the winter time on high-priced feeds. 



2. To compare a ration of cottonseed meal and hulls 

 alone with a second ration of cottonseed meal, hulls and 

 silage, and with a third ration of cottonseed meal, hulls 

 and Johnson-grass hay.
