How to Determine a Balanced Ration 



By referring to the foregoing tables, it will not be difficult to make a 

 balanced ration. To illustrate: 



We will take 100 pounds of corn. It contains 7.5 pounds of protein, 

 67.8 pounds of carbohydrates, and 4.6 pounds of fats. To determine 

 the amount of carbohydrates, including the fat, we will multiply the 

 digestible fats by 2.25 and add the product to the digestible carbo- 

 hydrates. By multiplying 4.6 pounds of the fats by 2.25, we have 10.35, 

 which, added to 67.8 (the carbohydrates), gives a total of 78.15. By 

 dividing this by the protein, which is 7.5, we have 10.4, or, in other 

 words, the ratio of corn is 1 to 10.4, which is manifestly an unbalanced 

 ration, for it contains too great a proportion of carbohydrates. In 

 order to make it a desirable feed, it should be fed with something con- 

 taining a larger per cent of protein. Among the principal carbohydrates 

 is corn, corn-fodder, silage, timothy hay, millet, Johnson grass, wild 

 oats, blue grass, sugar cane, kaffir, and prairie hay. A few of the 

 principal protein feeds are cotton-seed meal, gluten meal, wheat bran, 

 buckwheat middlings, flax-seed meal, alfalfa, clover, soy beans, cow 

 peas, and all other legumes.
