﻿MEDICAL MILK COMMISSIONS AND CERTIFIED MrLK. 13 



is being elevated. It will show that it is practicable for any medical 

 association to form such a commission, which, once formed, will be 

 most useful in educating the public as well as the profession and in 

 creating a demand for a cleaner milk supply, and will thus further 

 the efforts of boards of health. 



THE PRODUCTION OF CERTIFIED MILK. 



EQUIPMENT AND METHODS. 



In the following pages is given a short description of the "equip- 

 ment and methods that are used at the present time among the various 

 dairies that produce certified milk. 



The Dairy Division is ready at any time to furnish working blue 

 prints for the construction of barns and milk houses in which certified 

 milk may be produced and handled. 



STABLES. 



The stables in which the cows are housed for the production of 

 certified milk are built of various materials and vary greatly as to 

 their arrangement and cost. In the past certified stables have been 

 built mostty of wood or brick, but of late there have been a few 

 stables erected entirely of concrete. Feeding floors, walks, and gut- 

 ters are nearly always built of cement, and in a number of cases the 

 platform on which the cows stand is also built of this material. 

 Some certified dairies use wood for this purpose, and a few are using 

 cork brick for the cows to stand on. 



While many of the certified barns at the present time are built 

 with a storage loft for feed overhead, it is thought that the best 

 practice is to have the cows in a separate one-story structure. 



A great deal of money has been spent in some certified-milk plants 

 in finishing the stable in an elaborate manner with tile and expensive 

 trimmings. Experience would seem to show that good results can 

 be secured in an inexpensive barn, provided the proper precautions 

 are observed. The floors should be smooth, nonabsorbent, and easily 

 cleaned ; the gutters should be capacious ; the walls and ceilings should 

 be absolutely smooth so that they may be easily kept free from dust 

 and other dirt. Square corners and ledges should be avoided. The 

 barns which are most easily kept clean are built with rounded corners 

 and no horizontal ledges where dust may accumulate. It facilitates 

 work if running water is available in a barn, so that the floors and 

 walls may be washed down with a hose. 



At least 500 cubic feet of air space and 4 square feet of window 

 glass per cow should be allowed. Many certified stables are built 

 with a much greater window allowance. Sunlight acts as a disin- 

 fectant in the stable and adds much to the attractiveness of the 

 building. 



Views of stables are shown in Plates I and II.
