150 MASS. EXPERIMENT STATION BULLETIN 186. 



Wheat bran contains more ash, protein and fat, and noticeably less 

 extract or starchy matter, than does the corn bran. In using corn bran 

 as a component of a dairy ration these differences, particularly the ash 

 and protein, would have to be given consideration. 



By applying the percentages of dry matter of the various feeds as given 

 in Table III to the amounts fed (Table II), the amounts of dry matter 

 fed can easily be obtained. Only the totals for the herds and the aver- 

 age per animal for each herd are given in Table V. 



Table V. — Total Amount and Average Daily Amount of Dry Matter 



consumed (Pounds). 



Experiment I. 



Corn Bran Ration. 



During the two experiments the total amount of dry matter consumed 

 by the cows receiving the corn bran ration was 12,920 pounds, while the 

 cows receiving the wheat bran ration consumed substantially the same, 

 or 12,945 pounds. Of these totals, 1,717 pounds represented corn bran 

 and 1,735 pounds wheat bran. For convenience the average daily amounts 

 of dry matter consumed per cow in the two rations of both experiments 

 are here tabulated.
