desirable to adjust the protein and carbohydrates fairly 

 closely in amounts to those in the standard. We might use 

 cotton-seed meal, or oil meal, as a trial, to balance up this 

 ration; but to use a home-grown product that is getting more 

 and more common, we will use soy beans, though they must 

 be fed cracked or ground. Let us then add 3 pounds of the 

 soy beans to the rest of the ration. Turning to the table of 

 the composition of feeding stuffs, on page 387, we find that:

 100 Ibs. contain 88.3 Ibs. 29.1 Ibs. 23.3 Ibs. 14.6 Ibs. 

 Then 3 Ibs. contain 2.65 Ibs. 0.87 Ibs. 0.7 Ibs. 0.44 Ib. 



Adding this to the total in the original ration, we have the 

 following:

Nutritive ratio, 1 : 5.9. Standard, 1 : 5.7. 



This ration shows a shortage in dry matter of 3 pounds, 

 a very slight increase of protein, and quite an increase in 

 fat. These differences, however, are not important. The 

 nutritive ratio agrees fairly well with the standard. There- 

 fore we may consider this ration properly calculated and cor- 

 rected to suit the animal's needs. 



The adjustment of rations to the standard is not usually 

 difficult. An increase in dry matter and carbohydrates is 

 easily secured with the hays or most of our common feed 

 stuffs. If a ration needs most attention in the protein, then 

 some concentrate such as soy beans, cotton-seed meal, 

 linseed oil meal, or tankage may be selected. The cost of the
