INCREASE IN RICHNESS WITH ADVANCE OF LACTATION PERIOD. 



For the six months* test every one of the fifty cows made a gain in 

 richness of milk incident to the advance of lactation period. By aver- 

 aging the four weekly composite tests for each cow for the first and last 

 month we have a fair basis for determining this gain without having to con- 

 tend with the fluctuations from week to week caused by things seen and 

 unseen. 



Comparing these averages for the months of May and October, we find 

 that every cow gained, from the Guernsey, Cassiopia, with a gain of only .1%, 

 to Queen, the Polled Jersey, with a gain of 2.01%. The average gain for 

 the five cows of the different breeds was as follows: French Canadian 1.07, 

 Jerseys 1.05, Polled Jerseys .90, Shorthorn .87, Guernseys .85, Brown Swiss 

 .7, Red Polled .65, Ayrshire .57, Holstein .48, Dutch Belted .39; the case of 

 Cassiopia was an exceptional one. Her average test for May was 4.34, June 

 3.99, July 4.12, August 4.36, September 4.71 and October 4.44, the gain 

 being steady from June to October, but low for October. 



Of the fifty cows, twenty-eight tested higher each month of the six 

 than for the preceding month ; eleven cows spoiled their progression by aver- 

 aging lower for some one month than for a preceding month. Of these 

 eleven, six dropped off during July, two during June and one each for 

 August, September and October. 



Six of the fifty cows were off an average test for two months of the six, 

 and the remaining five cows were high for just one month out of the six
