RATIONAL FEEDING OF ANIMALS 357 



amounts of nutrients in one pound are found by moving 

 the decimal point two places to the left. Multiplying 

 the pounds of food by the per cent, of digestible nutri- 

 ents, the pounds of digestible nutrients will be found to 

 be as follows : 



POUNDS OF DIGESTIBLE NUTRIENTS. 



Pounds. Protein. Fat. Carbohydrates, etc. 



10 Clover hay 0.68 0.17 3.58 



10 Corn fodder 0.25 0.12 3.48 



20 Mangel- wurzels 0.22 0.02 1.08 



5 Bran 0.64 0.16 2.00 



3 Oats 0.28 0.13 1.42 



2.07 0.60 11,56 



Compared with the standard ration, it will be observed 

 that the amounts of nutrients are approximately as given 

 in the table, suggesting that as far as total nutrients are 

 concerned, the ration is a reasonable one. The coarse 

 fodder, grain, and roots are about in the proportions 

 given in Section 477. As to the effects of the various 

 foods, the bran, mangels, and clover hay might possibly 

 prove somewhat laxative in character, and while the 

 ration supplies all of the requisites, as dry matter and 

 amount of nutrients, it would be necessary to note the 

 effect upon the animal, before concluding that it was sat- 

 isfactory in all respects. 



481. Nutritive Ratio. The nutritive ratio is the ratio 

 which exists between the digestible protein and the di- 

 gestible non-nitrogenous compounds. A nutritive ratio 

 of i to 6.7 means that for every i pound of crude pro- 

 tein there are 6.7 pounds of digestible non-nitrogenous 

 compounds. A wide nutritive ratio means a large
