and grain were eaten. The grain represented 57.3 per cent, of the 

 cost and the corn fodder 13.8 per cent. The grain supphed 44.8 

 per cent, of the total digestihle nntrients and the corn fodder 22.0 

 per cent. For the rest of the montli beets were fed in place of corn 

 fodder. The beets represented 18.3 per cent, of the cost of the 

 ration and the grain 53.1 per cent. The beets supplied lfi.5 per 

 cent, of the digestible nntrients and the grain 47 per cent. The 

 rations for the three periods did not differ mnch in composition. 

 The nutritive ratio for the third period was somewhat narrow-er 

 than for the others. The cost of the ration increased with each 

 change. 



There was an average loss in weight during the month of 

 about 18 pounds. The greatest daily average milk yield for the 

 lirst period was 25.5 pounds and the smallest 14.2 pounds. The 

 highest average percentage of fat was 6.41 and the lowest 3.79. For 

 the second period the extremes in daily average milk yield w^ere 

 25.5 pounds and 14.1 pounds and in average percentage of fat 5.74 

 and 3.33. For the third period the extremes in daily average milk 

 yield were 24.6 pounds and 13.5 pounds and in average percentage 

 of fat 6.07 and 3.17.
