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 repoi-ts : "I have watched the horses closely from the 

 beginning to the end of the experiment and have faUed 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 waa 

 found that the oat ration cost, at prevailing prices, 24.3 cents pe 

 day, while the ration containing brewers' grains cost 19.4 cent»^ 

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

 the cost of the oat ration — an insignificant amount perhaps fir a 

 single horse, but making an aggregate of great importance for 

 large establishments. 



According to Wolff, ' "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)
