EXPERIMENT STATION BULLETINS. 419 



At Webberville the production was lower, averaging for the two 

 years, 6,047 pounds per year, divided as follows: milk sold, 87.4%, 

 used on the farm, 12.4%, and returned from the factory, .2%. During 

 the winter season 4,064 pounds were produced and during the summer 

 season, 1,983 pounds, making a total of 6,047 pounds for the year with 

 an average test of 3.45% butter fat. 



Throughout the three years studied, milk production at Howell was 

 very uniform. The high point of production was during the months 

 of January, February, March, April, May, and June (figure III), while 

 the extreme low points were in August and September. At Webberville 

 the production was less per cow than that at Howell, but ran prac- 

 tically parallel throughout the year.
