8. Completing the ration—Comparing the nutrients in 
the feeds used with the standard, it will be seen there is a 
striking deficiency of protein. It will now be necessary 
to introduce into the ration one or more other feeds in 
order to correct the faults so evident in the trial ration. 
Since the greatest deficiency is in the protein, we must 
seek a supply from among such feeding stuffs as are par- 
ticularly rich in protein. The oil and the gluten meals 
are of this kind. Suppose we now try two and three- 
quarter pounds of cottonseed meal. The digestible nu- 
trients are ascertained in the same manner as before, 
and a second trial made.
