Each ration was fed to a group of four horses for a month, then 

 the two feeds reversed for a second month. Then followed a 

 period in which the stable ration prevailed with both lots, the 

 trial closing with a month's feeding of the two rations to the 

 original lots, as in the first instance. The veterinarian in charge 

 of the horses reports: ' 1 1 have watched the horses closely from the 

 beginning to the end of the experiment and have failed to dis- 

 cover any ill effects from the use of dried brewers' grains. The 

 horses fed the grains have been as healthy as I have ever known 

 them to be." The conclusions of the Station authorities were: 

 "That in both rations the nutrients furnished were sufficient to 

 maintain the weight of the animals under average work," and 

 " That on the whole, a pound of dried brewers' grains was quite 

 as useful as a pound of oats in a ration for work horses." It wa& 

 found that the oat ration cost, at prevailing prices, 24. 3 cents per 

 day, while the ration containing brewers' grains cost 19.4 cents, 

 a difference of 4.9 cents per day per horse, or twenty per cent, of 

 the cost of the oat ration an insignificant amount perhaps for a 

 single horse, but making an aggregate of great importance for 

 large establishments. 



According to Wolff, 1 "The effect of dried brewers' grains 

 has been found to be uncertain, and on that account their use 

 has been abandoned by the German war department. ' ' While 

 brewers' grains dried by any open-air process may be subject to 

 criticism, the charge cannot stand for grains which are dried 

 rapidly in partial vacuum. (183)
