The sample tested showed an average digestibihty. Brewers' 

 grains may be regarded as moderately digestible, having about the 

 same degree of digestibility as wheat bran. The protein and fat 

 have relatively high digestion coefficients, while only about one-half 

 of the fiber and extract matter are utilized by the animal. 



(d) Feeding Experiment with Cows. 

 Brewers'' Dried Grains vs. Wheat Bran. 



The experiment was completed with eight cows, but owing to the 

 unusual loss in weight and wide variations in percentage of fat in 

 the milk of the cow Pearl, her record was omitted, and the results 

 with seven cows are presented. 



Object of the Experiment : — The trial was conducted to note 

 the effect of brewers' grains on the general condition of the cows ; its 

 value for the production of milk as compared with a like quantity of 

 wheat bran ; and its influence, if any, on flavor and keeping quality 

 of the milk. 



Plan of the Experiment : — The cows were divided into two 

 lots, and fed by the reversal method, as described in detail under 

 the distillers' grain experiment. The care and weighing of the ani- 

 mals, method of feeding and sampling of milk were the same as in 

 that experiment.
