BULLETIN 1400, U. S. DEPARTMENT OF AGRICULTURE 
The seasonal distribution of production is largely determined by 
the time of year the cows freshen, the quality of their pasturage, and 
the way they are fed. The feed requirements for producing a high 
proportion of the milk during the winter months will be considered 
later. 
Milk produced under such conditions that it is kept unusually 
clean commands a premium or "bacteria bonus" in several portions 
of the area surveyed, the payment of the bonus being contingent 
Fig. 6. 
-Clean milk can be produced economically, even in old barns. These two barns were 
brought up to date at little expense by adding cement floors and larger windows 
upon the milk containing below a specified minimum number of bac- 
teria per cubic centimeter. Farmers located near a shipping station 
where they can take advantage of this demand for a higher quality 
product, can increase the price they receive with little extra expense 
other than that of more care in milking and with the milk utensils.

An individual farmer can increase the price of his milk by produc- 
ing a cleaner product, by producing more during the winter months, 
or by producing milk of higher fat test. The following discussion 
will bring out which of these ways yield profits.
