(d) Feeding Experiment with Cows. 



Biles Fourex vs. Buffalo Gluten Feed* 



Object of the Experiment : — The object of this trial was to 

 note whether the animals ate the grains freely, and the effect upon 

 their general condition ; the comparative yield of milk, milk solids 

 and milk fat with the two rations, and the consequent economy of 

 distillers' grains as a dairy feed ; and the effect, if any, of distillers' 

 grains upon the flavor and keeping quality of the milk. 



Plan of the Experiment : — Six comparatively fresh cows were 

 divided as evenly as possible into two lots of three each. In the 

 first half three of the cows received the distillers' grain ration for a 

 period of six weeks (two weeks of which were preliminary) at the 

 same time the other three received the Buffalo gluten feed ration. In 

 the second half the conditions were reversed.

General Care and Feeding of the Animals : — The experiment 

 was carried out in the station barn, especially set apart for such 

 work. Each animal was kept in a roomy stall, well carded and 

 turned daily into a yard for exercise. The daily feed was given in 

 two portions, and water was kept constantly before each animal. 

 The cows were in good condition and quite contented. 



Weighing the Animals: — The animals were weighed on three 

 consecutive days at the beginning and end of each half of the trial. 



Sampling Feeds: — The coarse fodders were sampled three times 

 during each half of the trial, dry matter determinations made imme- 

 diately and composite samples analyzed. Small samples of the 

 grains were taken daily and placed in glass-stoppered bottles. 



*Buffalo gluten feed has essentially the same amount of total digestible nutrients as 

 has the distillers' grains, and is recognized as a very satisfactory feed for dairy animals ; 

 hence it was selected as a suitable product with which to compare the grains.
