good condition. Our horse weighs between 950 and 

 1,000 pounds, and we have a supply of oats, shelled 

 corn, and clover hay, with which to feed him. How 

 can we mix these foods so as to supply him the proper 

 amounts of protein, fat and carbohydrates ? By refer- 

 ring to Table YIII we find that a horse at moderate 

 work, for every thousand pounds of live weight requires 

 each day 22 pounds of dry matter, containing of diges- 

 tible nutrients, 1.8 pounds of protein, .6 of a pound 

 of fat and 11 pounds of carbohydrates; giving a nutri- 

 tive ratio of 1 to 6.9. In mixing our foods to supply 

 this ratio we will start by taking 10 pounds of corn. 

 Referring to Table VII we find that this amount of 

 corn contains 8.9 pounds of dry matter, .8 of a pound 

 of digestible protein, .46 of a pound of digestible fat, 

 and 6.59 pounds of digestible carbohydrates. Next we 

 take 10 pounds of clover hay, which we find from the 

 same table contains 8.47 pounds of dry matter; and of 

 digestible nutrients, .76 of a pound of protein, .20 of a 

 pound of fat, and 3.84 pounds of carbohydrates. 

 Adding these figures together we have 17.4 pounds of 

 dry matter, 1.6 pounds of protein, .66 of a pound of fat, 

 and 10.4 pounds of carbohydrates. To complete our 

 required ration we need only 4.6 pounds of dry matter; 

 therefore 10 pounds of oats would give more than is 

 needed, so we will take 5 pounds. This amount of oats 

 according to Table VII gives us 4.45 pounds of dry 

 matter; and of digestible nutrients, .46 of a pound of 

 protein, .21 of a pound of fat, and 2.36 pounds of 

 carbohydrates. Adding these figures to those for hay 

 and corn we have:
