INFLUENCE OF SEASON" OF FRESHENING ON DAIRY COWS. 3 



VALUE OF PRODUCTS. 



Table 2, which, is derived from a tabulation of the records of the 

 64 associations, shows how many times the cows that freshened each 

 season ranked first, second, third, and fourth in average yearly price 

 received for milk or butterfat produced by the cows that freshened 

 within that season.

butterfat or milk.

The figures do not refer to the price received for the product at 

 any season of the year, but to the average price received during the 

 entire year for the product produced by cows that freshened at a 

 certain season. 



There were two associations in which no cows freshened in sum- 

 mer. This accounts for the summer ranks adding up to only 62. 



As there were ties for first place in some associations, the total 

 number of times the four seasons received first place is greater than 

 the number of associations compared. The table shows that in av- 

 erage price received for butterfat produced during the year, fall 

 freshening ranked first 39 times ; summer, 36 ; winter, 12 ; and spring, 

 12. The cows that freshened in the fall may not have freshened at 

 the time of year when prices were highest, but they produced most 

 of their milk at the time of year when prices were highest. 



MILK AND BUTTERFAT PRODUCTION. 



In milk production the ranks of the four seasons were as shown 

 in Table 3 :
