Tlic above results show no striking variations in the yiehls. 

 The beet pnlji ration produced 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 due partly to the 

 superior mechanical etfect of the pnlp, although this is pure 

 assumption. 



Average Com'position of the Herd Milk. 



DitTerences in the composition of the milk are not noted. 

 Food Cost of Milk and Butter. 



The beet pulp cost some $6 a ton less than the coTn 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.
