TABLE XVIII. THE NUTRITIVE RATIO OF 26.8 POUNDS OF 



OATS 



Thus in this case, X 26 . 8 pounds = 24 pounds, the 



100 



amount of dry matter; 



11.4 



Too 



X 26 . 8 = 3 . 05 pounds protein, 



etc. Of this protein, 77 per cent or T V T is digestible; hence 

 rVoX3.05 pounds = 2. 35 pounds digestible protein, simi- 

 larly, T 3 oVX2.89 pounds = 0.90 pound digestible crude 

 fiber, etc., etc. The nutritive ratio = digestible protein: 

 (digestible carbohydrates + 2.25 X fat) = 2.35 : (0.90 

 + 12.26+2.25X1.15) = ! : 6.7. 



The foregoing calculation shows that oats contain a 

 nutritive ratio well suited to the needs of the horse, but 

 that the proper amount of digestible dry matter contains 

 too large an amount of nutrients; therefore, even with oats, 

 some hay should be fed to give bulk. When this is done, 

 the amount of oats fed will be reduced. 



EXAMPLE 2. The calculation of a ration for a dairy 

 epw giving 27.5 pounds of milk will serve as an example of 

 a more complicated problem. Suppose that it is proposed
