Then 



r iguring the corn silage next, we find that 



Dry matter Protein Total nutrients 



100 lbs. contain 20.3 lbs. 1.1 lb. 17.7 lbs. 



30 lbs. contain 7.89 lbs. 0.33 lb. 5.31 lbs. 



Figuring the Corn and cob meal next, we find that 



Dry matter Proteiii 

 100 lbs. contain 89.6 lbs. 6.1 lbs. 



Then 10 lbs. contain 8.96 lbs. 0.61 lb. 



Coming last to bran, we learn that 



Dry matter Protein 



100 lbs. contain 89.9 lbs. 12.5 lbs. 

 Then 3 lbs. contain 2.70 lbs. 0.37 lb. 



If we have copied these figures as worked out, into the 

 blank places arranged for them in the table on page 94, 

 then we shall have the following, after we have added up the 

 totals.

The above table shows that the proposed ration, com- 

 pared with the standard, is satisfactory in the amount of dry 

 matter, but is from 0.03 to 0.39 lb. short in digestible pro- 

 tein, and lacks from 1.5 to 3.9 pounds of total digestible 

 nutrients, with a slightly wider nutritive ratio than the 

 standard calls for. 



The third step in computing the ration will be to correct 

 or improve it so that it will compare favorably with the 

 standard. Not much is really necessary to improve this 

 ration, for the dry matter already supplied is properly 

 adjusted, and there is but a small shortage in digestible pro- 

 tein. We should, however, have at least a pound and a half
