a corresponding decrease in the washed bran. In this way.the 
transition was successfully accomplished. 
Ration 1—Fed from noon March g to the morning of March 109. 
Transition period—From noon March 19 to the morning of 
March 23. 
During this time two pounds of washed bran were substituted 
daily for 2 pounds of the unwashed and when the ration contained 
6 pounds of washed bran, one-half pound of wheat gluten was 
added daily to supply the deficiency in protein. At the end of this 
period the feces had become hard and dry. 
Ration 2.—From noon March 23 to the morning of April Io. 
Ration 1.—At noon April 10, the cow was suddenly transferred 
to ration 1 which she ate heartily for two days and then refused 
further portions. She was then placed on a ration containing 4 
pounds of unwashed bran and 6 pounds of washed bran, which she 
completely consumed on April 12. 
Transition period—From noon April 12 to the morning of 
April 18. 
Starting with the ration which was fully consumed on April 12, 
a change was made gradually to ration 1 by the daily substitution of 
1 pound of unwashed bran for an equivalent quantity of the washed, 
the wheat gluten being decreased by one-half pound. 
Ration 1.—From noon April 18 to the morning of May 2. 
Transition period.—This occupied from noon May 2 to the morn- 
ing of May 6. 
This transition was accomplished by the daily substitution of two 
pounds of washed bran for an equal weight of the unwashed with 
a daily increaase during the entire period of one-half pound of 
wheat gluten. 
Ration 2——From noon May 6 to the morning of June 4. After 
June 4 the animal was placed with the Station herd and slowly 
brought to the ordinary milk ration. 
During this experiment a sudden change from the high idee 
ration to the one containing washed bran was found to be inad- 
visable. Abundant evidence was accumulated concerning the drier 
condition and firmer consistency of the feces when the washed bran 
was fed, apparently establishing beyond question the comparatively 
laxative effect of the whole wheat bran.
