TABLE IX 



Average Results (Pounds) 



Table VIII shows extremes of from 72 to 195 pounds of dry mat- 

 ter fed for maintenance and to produce 100 pounds of milk, while the 

 average as given in Table IX is 11 7.9 pounds. 



In case of the digestible matter the extremes are 53 and 144 

 pounds and the average is 76.4 pounds. The extremes and the aver- 

 age do not mean that such amounts of dry and digestible matter were 

 absolutely necessary, because the animal might have done equally as 

 good work with somewhat less food than was actually fed. A con- 

 tinuation, however, of liberal feeding after the first few months of 

 lactation is favorable to keeping up the yield during the entire period,
