"The question often asked me is, ^How do you mix 

 your feed?' Suppose it is desired to feed corn, oats, and 

 bran. According to the best authority we have, the 

 nutritive ratio should be 1 to 5.4. By nutritive ratio is 

 meant that the digestive albuminoids should be mixed 

 with the starch, sugar, and fat of the food in the pro- 

 portion of 1 of the former to 5.4 of the latter. Sup- 

 pose now I take the average analyses of corn, oats and 

 bran, and determine how much digestible ingredients 

 are contained in two bushels oats, one bushel corn, and 

 fifty pounds bran. It is as follows : 



DigeshUe. 



Protein. Carbo-Hydrates. Fat. 



Pounds. Pounds. Pounds. 



64 pounds oats. 6.22 31.04 2.49 



56 pounds corn 5.10 37.56 2.33 



50 pounds bran 6.01 22.01 1.52 



Kutritive ratio of above is 1 to 6.1, which shows that I 

 should add more flesh-forming food. To be brief: If 

 you mix sixty-four pounds oats, twenty pounds corn, 

 and fifty pounds bran you will have a nutritive ratio of 

 1 to 5.6, which is approximately the one recommended ; 

 112 pounds corn, 100 of shorts, and fifty of bran gives a 

 nutritive ratio of 1 to 5.4, and with corn at twenty-five 

 cents^ shorts at twelve dollars, bran nine dollars, and 

 oats twenty-two cents, is cheaper ration for me than 

 corn, oats, and bran; the difference is about five cents 

 per 100 pounds; 100 pounds of oats, twenty-five of wheat, 

 and fifty of bran will do as well for cows as any given 

 at a cost to me of seven cents per hundred more. Bran 

 itself is not the best feed for cows. It should be mixed 

 with some feed richer in starch, sugar and fat, if j^ou 

 desire to feed economically and for profit. Feeding bran 

 increases the per cent of cream. By feeding ten pounds
