The Production of Clean ^Iilk 



T929 



Another requirement of a sanitary cow stable is good light, which is 

 necessary in order that the work may be properly done and that the 

 general health of the animals may 

 be good. A good coat of white- 

 wash applied to the interior of the 

 stable at least twice a year is a 

 ver^' inexpensive and cfificicnt 

 method of keeping it light and 

 clean; a bright, clean stable is a 

 great incentive to the production 

 of clean milk. Sunlight is one of 

 our greatest natural disinfectants, 

 and the stable should have plenty 

 of window space so that the sun- 

 light can enter. If light is lacking 

 on the underground side of a 

 basement stable, a window may 

 be cut in the floor above according 

 figure 132. 



Good ventilation, as well as plenty of sunlight, is necessary for the 

 health of the animals. I?very dairy stable should have soinc system of 

 ventilation to keep the air fresh and pure and the cows comfortable and 

 unexposed to injurious drafts. Poor ventilation usually means poor 

 sanitary conditions. One good method of ventilation is the King system, 

 but this will not work unless the building is tight. Simple direct openings

are very effective, but they are likely to make a direct draft, especially 

 if they are exactly opposite each other. The cloth curtain system has 

 two advantages in that it is inexpensive and the curtains can be easily 

 replaced when they become dirty, but the main disadvantages are that 

 this system ma}^ collect dust and may not be suitable for cold climates.
