In the same way we arrive at the digestible amounts 

 contained in 6 Ibs. of shelled corn, 6 Ibs. of wheat bran 

 and 10 Ibs. of timothy hay. Then we add together the 

 dry matter and digestible ingredients in the cotton-seed 

 meal, shelled corn, wheat bran and timothy hay and 

 compare it with the standard.

To reduce our fat to terms of carbohydrates we 

 must multiply by 2.25. .804X2.25 = 1.809. 11.032 

 -|- 1.809 = 12.841 Ibs. total digestible carbohydrates. 

 12.841 (total digestible carbohydrates) H- 2.224 (di- 

 gestible protein) = 5.8. That is, the nutritive ratio 

 is i :5-8. This trial ration is stated as follows:

Balancing the Ration. This trial ration is not en- 

 tirely satisfactory. It is almost correct for dry matter
