The amount of the basal ration, common to every cow, 

 averaged practically the same for each lot, whether the 

 additional food was cowpea hay or wheat bran. 



Incidentally it was ascertained in this test that run- 

 ning the cowi>ea hay through a feed cutter, so as to 

 chop it into lengths of about two inches did not decrease 

 the proportion of hay rejected.

*1411 pounds of cowpea hay offered and charged against the cows. 



The am®unt of wheat bran consumed by six cows in 30 

 days, in addition to the basal ration, was 1,176 pounds. 

 Adding also the portion of the hay which was unused, 

 and which consisted of nearlv worthless coarse stems, 

 Ave must charge the cows with 1,411 pounds of cowpea 

 hay. This has been done in the following table in cal- 

 culating the cost of food required to make a pound of 

 butter.
