COMPARISON OF CONCENTRATES FOR FATTENING STEERS. 11 
AVERAGE DAILY RATIONS. 
Table 5 shows the average daily rations by 28-day periods for each 
lot. As a comparison was to be made of the concentrated portion of 
the rations, each lot was fed as nearly the same amounts of roughage 
as possible. During the first 28-day period the amount of corn silage 
and oat straw consumed by each lot was the same. After that the 
steers were given what feed they would clean up within 1 hour after 
feeding. The silage ration was kept practically the same for all lots, 
so that the variations occurred chiefly in the amounts of oat straw 
consumed. Thecattle were permitted to eat as much oat straw as they 
desired after being fed the silage.

1 Johnson grass hay fed instead of oat straw during last 174 days. 
The steers of Lot 1 in this experiment, which received cottonseed 
meal as the sole concentrate, were fed as much of it as was deemed 
advisable for a feeding period of 141 days. Lots 2 and 3, which re- 
ceived broken-ear corn and shelled corn, respectively, were given an 
allowance of cottonseed meal which was about one-half that received 
by Lot 1. Lots 2 and 3 received exactly the same amounts of cotton- 
seed meal and. practically the same amount of corn without consid- 
ering the cob. 
The difference in the amounts of roughage consumed by each lot 
would be expected, since lots 2 and 3, which were getting broken-ear 
corn and shelled corn, were getting slightly larger amounts of roughage 
material in their grain allowance than Lot 1, which received cotton- 
seed meal only.
