CHAPTER IX 
CARE AND MANAGEMENT OF DAIRY CATTLE 
Tue production of clean milk calls for exacting care of the 
dairy cow. This is so important in milk production that milk is 
classified according to the care given the herd. 
SANITARY MILK 
By sanitary milk is meant a clean, wholesome product produced 
under sanitary conditions. The principal factors to be considered 
in its production are the cow, the stable, the milk house, the 
milking, and the cooling and storing of the milk. 
259. The cow. — In the production of clean milk extra care 
must be given the cows. They must be curried daily to remove 
the loose hair and dirt. The udder and rear parts of the cow 
should be clipped, thus removing the long dirt-catching hair and 
rendering the parts much more easily cleaned. The udder should 
be wiped with a damp cloth just before milking. Care should be 
taken to feed clean, nutritious foods and such as will not con- 
tribute an undesirable flavor to the milk. The drinking water for 
the cows should be clean, fresh, and the tanks protected from 
possible contamination. ‘ 
260. The stables. —If one is to produce sanitary milk, the 
stable must be kept clean. This applies to dust, cobwebs, and 
the like, as well as to the manure and litter. Much light and good 
ventilation are essential. The floors should be of cement. The 
gutters’ and litter should be cleaned out twice daily, and the 
material hauled to the field, or placed in a protected water-tight 
pit outside the barnyard, of sufficient distance to prevent odors
