 The following formula illustrates the method of find- 



ing the nutritive ratio : 

 Carbohydrates+(fatX2.25) 



nutritive ratio. 



protein 



For example, suppose we wish to find the nutritive 

 ratio of the following ration: (Horse weighing 1,000 

 pounds, doing medium work.) 



Timothy hay 15 pounds 



Corn .10 pounds 



Cotton-seed meal 3 pounds 



Solution : 



In 100 pounds of timothy hay there is 86.8 Ibs. 

 dry matter, 2.8 protein, 43.4 carbohydrates, and 1.4 

 fat. (See table below.) 

 In 15 pounds hay there are : 



15-100 of 86.8 dry matter, 13.02 pounds. 

 15-100 of 2.8 protein, .42 pounds. 

 15-100 of 43.4 carbohydrates, 6.51 pounds. 

 15-100 of 1.4 fat, .21 pounds. 

 In 10 pounds corn there are : 



10-100 of 89.1 dry matter, 8.91 pounds. 

 10-100 of 7.9 protein, 7.9 pounds. 

 10-100 of 66.7 carbohydrate, 6.67 pounds. 

 10-100 4.3 fat, .43 pounds. 

 In 3 pounds cotton-seed meal there are : 

 3-100 of 91.5 dry matter, 2.74 pounds. 

 3-100 of 38.1 protein, 1.14 pounds.
