observation, either three poiiuds of gluten meal or three pounds of 

 old process linseed meal or three pounds of cotton seed meal to com- 

 plete the grain feed part of the daily diet. One half of tlie grain 

 feed was fed with some of the coarse feed at the time of milking in 

 the morning and the other half in a similar way during milking in the 

 evening. The remainder of the coarse fodder was given at noon and 

 after milking in the evening. 



The consumption of the coarse fodder constituents of daiPy diet, 

 as far as quantity is concerned, was in most instances controlled by 

 the appetite of each animal. To satisfy the latter a small excess was 

 offered and the remaining portion subsequently weighed back. This 

 practice was adopted in particular in case of rowen when fed alone 

 as coarse feed, and in case of mixed ensilage and of corn stover. 

 Five pounds of rowen, however, was always fed per day to each cow 

 whenever the mixed ensilage of corn and soja bean formed a promi- 

 nent part of their daily diet. The daily fodder rations, which are 

 below in detail described, represent the average composition of the 

 daily diet used, per head, during the different succeeding feeding 

 periods. 



The subsequent record of the cost of the different fodder ingre- 

 dients used in the daily fodder ration can assist in recognizing the 

 basis for our calculations of the cost of the latter.
