The above results show no striking variations in the yields. 

 The beet pnlp ration prodnced substantially 2 per cent, more 

 milk and milk solids than did the corn meal ration. This is 

 within the limit of error. It may have been dne partly to the 

 superior mechanical eiTect of the pulp, although this is pure 

 assumption.

The beet pulp cost some $G a ton less than the corn meal at 

 the time the experiment was in progress ; hence the cost of the 

 milk produced was also less (some 6 per cent.). 



Dry and Digestible Matter required to produce Milk and Milk Ingredients 



(Pounds) . 



The above figures include the food material required for 

 maintenance. They show that a little less dry and digestible 

 organic nutrients were required to produce like amounts of 

 milk and milk ingredients with the beet pulp than with the corn 

 meal ration.
