fed with silage during the winter months. To get information on 
this subject the experiment hereinafter described was planned and 
executed. 
OBJECT AND PLAN OF WORK. 
The objects of this experiment were to make a comparison between 
the feeding values of cottonseed meal and cold-pressed cottonseed 
cake, when each was fed to steers with a roughage ration of corn silage, 
and to study the effects of the addition of corn-and-cob meal to a 
ration of cottonseed meal and corn silage. 
The steers used in this work were bought during the fall months 
after having been on pasture during the summer without other feed. 
They were placed in the cotton and cornstalk fields until the feeding 
was begun and were given a small allowance of cold-pressed cottonseed 
cake. Nearly all the 75 steers used in the test were horned when 
purchased. They were dehorned two weeks prior to the beginning 
of the experiment. 
Individual weights of the steers were obtained on November 30 
and December 1. After weighing on the second day the steers were 
divided into three lots of 25 each and started on feed. The division 
was made so as to have the three lots as nearly equal in weight and 
quality as possible. 
CATTLE USED. 
The steers used in the test were grade Shorthorns, Herefords, 
Aberdeen-Angus, and Red Polls. Their breeding was from one-half 
to seven-eighths pure bred. They were all raised in Madison County, 
Miss., and were somewhat better than the average of steers found in 
the State. They had been run on good grass pastures during the 
previous summer, and averaged 860 pounds the day they were 
placed in the feed lots. After they were brought to the farm they 
were given a small allowance of cottonseed cake and most of them 
were in fair condition at the beginning of the experiment. At that 
time the steers were all about three years of age. 
CHARACTER AND PRICES OF FEED. 
The cottonseed meal used in the experiment was of very good 
quality; the analysis showed a protein content of about 40 per cent. 
The cold-pressed cottonseed cake likewise was of good quality and 
showed a protein content of about 27.5 per cent. 
The silage used was mixed; about one-half of it was made of corn, 
and the other half of corn and sorghum. Some of the corn used 
for silage would have averaged about 35 bushels an acre in production 
of grain. Some of it, however, was rather poor, but the silage on 
the whole was considered excellent by the feeders. 
During the second and third 28-day periods a small amount of 
cowpea hay was fed to each of the three lots. During this time the
