﻿MEDICAL MILK COMMISSIONS AND CERTIFIED MILK. 15 



FEEDING. 



On account of the dust and odors which arise from the feeding 

 of hay, grain, and silage, nearly all certified dairies prefer to do the 

 feeding after milking has been completed. 



BARNYARD. 



The barnyard should be well drained and kept free from all filth. 

 If good natural drainage can not be secured it is sometimes necessary 

 to fill in the barnyard with coal ashes, gravel, shells, or some other 

 drainage material. Sometimes underdrains are put in to carry away 

 superfluous moisture. As the cows often lie down in the barnyard,

it is important to keep the yard clean, so that they may not become 

 unnecessarily dirty. 



UTENSILS. 



Particular attention is paid by certified dairies to the construction 

 of the utensils which come in contact with the milk. It is most de- 

 sirable to have the utensils as free as possible from all crevices and 

 inaccessible parts. The simplest utensils are the ones which are the 

 most readily cleaned, and hence the danger of contamination from 

 them is less. Small-top milk pails are used by practically every 

 certified dairy. There are many forms of the small-top milk pail 

 in use at the present time, and it is generally known that these pails 

 are responsible for the elimination of many bacteria from milk. 

 Figure 1 shows a small-top pail which can be made from an ordi- 

 nary milk pail by the addition of a hood. This pail will take the 

 place of some of the more expensive kinds and do very satisfactory 

 work.
