﻿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 12| 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 day. 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
