STATE BOARD OF AGRICULTURE. 



THE DATA. 



The data are presented on the basis of the average per cow of the 

 entire field, and are given for each calendar month as well as by the 

 season and the year. No attempt v/ill be made to go into individual 

 herd records in this bulletin, due to the large amount of space they 

 would require. Nevertheless all these herd records are on file and 

 may form parts of future publications. 



The winter season covers the winter feeding period (October 15 to 

 May IG) and the summer season covers the summer feeding period 

 or pasture season (May IG to October 15). These dates were selected 

 as being the nearest point of demarcation between the two seasons. 



Feed Costs. 



Feeds constitute the largest item of expense in the dairy business, 

 comprising nearly one-half (18.9% at Howell and 4G.1% at Webber- 

 ville) of the total cost of milk production. 



Tables II and III give the amount of feed fed per cow for each month 

 as well as for the winter and summer season and the yearly total. 



TABLE II.— AVERAGE MONTHLY FEED REQUIREMENT PER COW AT HOWELL. 



Three bottom lines of the table show the amounts of feed for winter and summer seasons and the yearly 



total.
