BUSINESS METHODS IN FEEDING 133 



mixed hay, wheat bran and corn and cob meal. (See 

 Appendix.) For a trial ration we will combine the 

 feeds in the following proportion (these amounts 

 the author has frequently found in use by dairy- 

 men) : 



Comparing the nutrients furnished by this ration 

 with Wolff's standard, as given in table, we find 

 that while the dry matter and nutrients are not far 

 from the standard, the protein is much too low, 

 the carbohydrates and fat are somewhat too great 

 and the nutritive ratio too wide. Had we studied 

 carefully the nutritive ratio of the four feeds enter- 

 ing into the ration we should readily have seen that 

 with the exception of wheat bran they are all wider 

 than the standard. It is evident that one of the 

 three grains must be substituted for one that is 

 richer in protein, or, in other words, a very narrow 

 nutritive ratio. Consulting the table, we find that 

 among such are linseed meal, cottonseed meal, 

 gluten feeds, brewers' grains, etc. As cottonseed 

 meal is one of the richest, and furnishes protein at 

 a comparatively low cost, we will substitute two 

 pounds of this for two pounds of the corn-and-cob 

 meal in the ration. 



Again taking the figures from the table (Appen- 

 dix) ; we have ;
