THE FEEDING OP THE ANIMAL

the oxygen and hydrogen are in the proportions in which they 

 occur in water, two atoms of hydrogen to one of oxygen (H2O 

 is water. 1306). The carbo- 

 hydrates are sometimes called 

 amyloids, that is, starch-like 

 materials. 



453fl. The determination 

 of the nutritive ratio is very 

 simple. For example : clover 

 hay of average quality con- 

 tains say 1A% of digestible 

 protein, 11.7% of digestible 

 fiber, 26.3% of digestible car- 

 bohydrates other than fiber, 

 and 1.9% of digestible fat. 

 Then 2% times 1.9 is 4.3 ; 

 to this is added 11.7 and 26.3, 

 making in all 42.3, or the 

 stareh -equivalent of all the 

 heat- and fat-forming nutri- 

 ents. Then 42.3 divided by 

 7.4 equals 5.7. The nutritive 

 ratio of clover hay is, there- 

 fore, 1:5.7.

 from any food depend in large 

 measure upon the 

 housing and care 

 which the animal re-
