It will be seen that Herd I., which received the bran 

 ration during both periods, made a slight gain during the 

 second period in the quantity of milk and milk ingredients ; 

 while Herd H., which received the silage ration in the sec- 

 ond period, underwent a slight loss. The difterences are so 

 slight as to prevent any positive conclusions. They indi- 

 cate, however, that the bran ration produced slightly better 

 results than the silage ration, due possibly to the excess of 

 protein in the former ration.
