MEDICAL MILK COMMISSIONS AND CERTIFIED MILK. 19 
Some grade or native stock is found in most of them. There are 
several herds of registered animals. The breed is not considered of 
special importance with most of the commissions, provided that the 
composition of the milk produced is within the limits of the stand- 
ards prescribed. Provided that the health of the animals is perfect, 
it makes very little difference apparently what the breed is. 
QUANTITY AND QUALITY OF THE MILK. 
The amount of certified milk produced daily by certified dairies 
ranged from 12J to 6,000 quarts. The average daily production per 
dairy was found to be 747^ quarts. The average production of all 
the cows of all the dairies reporting is somewhat higher than that 
found in market milk dairies, but it is still far too low. An average 
of all the answers received showed that the production amounted to 
8.3 quarts of milk per cow per clay. The fat in the milk as reported 
varies from 3.2 to 6 per cent, and averages about 4.3 per cent. 
This is a slightly lower average than was found in the investi- 
gations made in 1907. The total solids as reported by the various 
dairies ranged from 11.74 to 14.5 per cent, with an average for all 
dairies of an even 13 per cent. 
BACTERIA IN THE MILK. 
The average bacterial counts of the milk from the dairies reporting 
varied considerably. One dairy claimed that their count ranges from 
absolutely sterile plates up to 1,000 bacteria per cubic centimeter. 
Three dairies reported counts of 20,000. The average bacterial count 
of all the dairies reporting was 4,069 per cubic centimeter. Some 
extremely low averages were reported, one dairy having an average 
count for one year of 655 bacteria per cubic centimeter. Still an- 
other dairy reported a seven weeks' average of 600 bacteria per cubic 
centimeter. 
RETAIL PRICES OF CERTIFIED MILK. 
The producers' reports on the retail price of their product shows 
that the lowest price received is 10 cents a quart, which price was 
reported by four dairies. The highest retail price was 20 cents a 
quart, which is received by two dairies. Averaging all the replies, 
it was found that the average retail price of certified milk is 14.3 
cents a quart. 
AGE OF MILK WHEN DELIVERED. 
Milk commissions have striven for the delivery of certified milk 
as soon after it is produced as possible; all other things being equal, 
the sooner it is delivered and consumed the better. In answer to 
the question as to the average age of certified milk when delivered, 
92 producers returned answers which showed that some milk was
