The two rations were practically of equal value, 

 \\li'^ther judged bv the amount of milk or of butter 

 produced. During the entire period covered by (lie ex- 

 periment and on both rations the average daily yield 

 of butter exceeded one pound per cow. 



Assuming that manure and skim milk balance the 

 labor of caring for the cows and that butter is worth 

 25 cents per pound we have the following financial 

 staivment:

By substituting vetch hay for wheat bran there was 

 a saving of 2.4 cents, or 26 per cent on the cost of each 

 pound of butter. 



Not only does the vetch hay pay a profit when fed, 

 as compared with wheat bran, but it afforos an addi- 

 tiounl i-rofit if produced at a lower cost thari .|10 per 



t(UI. 



To sum up the whole comparison : Practically as 

 much butter and milk was afforded by 834.6 pounds of 

 vetch bay actually consumed as by 890.4 pounds of 

 wheat bran. Hence each pound of vetch hay consumed 

 was slightly more effective than a x>ound of wheat bran. 



If we charge the cows also with the small amount of 

 vetch hay that was fed, but not consumed, we find that 

 a ton of vetch hay was equal to a ton of tvheat hran ahen
