Average Dry and Digestible Daily Nutrients consumed by Each Cow 



(^Pounds'). 



Herd I. : both periods, bran ration. 



Herd I. received the same quantity of digestible nutrients 

 during both periods. Herd 11. received more total digest- 

 ible matter in the first period than did Herd L, but the 

 nutritive ratio of the fodder groups was the same. In the 

 second or silage period Herd II. consumed rather more 

 total digestible nutrients than in the first period, but less 

 digestible protein, the nutritive ratio being somewhat wider 

 (1 : 6.5, instead of 1 : 5.4). This increase of digestible mat- 

 ter consumed was due to the higher digestibility of the corn 

 -and cob meal.
