Managing the Dairy Herd 87 



It is useless to try and ventilate a poorly built, cold 

 barn. It is impossible to ventilate to any satisfaction 

 without a certain degree of heat. There are companies 

 who make a specialty of ventilation. They publish 

 books that are useful and instructive to anyone who 

 may desire this information. The King system is 

 recognized as being the best and most efficient. 



Proper Treatment for Cow Consumption or Tuber- 

 culosis. 



The seriousness of this plague can be best under- 

 stood when it is explained that it causes the loss of 

 $15,000,000 yearly to dairymen and that today ten 

 per cent of dairy stock is infected. It might be well 

 to here state that the chief source of the spread of the 

 disease is the buying and selling of cattle already 

 infected. 



However, it is not our purpose here to dilate upon 

 the spread of this disease, but rather to suggest means 

 that have been found effective in protecting the cattle 

 not already infected. 



Dr. A. S. Alexander, professor of veterinary science, 

 University of Wisconsin, advises all dairymen to use 

 only healthy sires and dams in stock breeding. He 

 advises each dairyman to allow each cow or bull not 

 less than 600 to 800 feet of air space and not less than 

 four square feet of window glass lighting space in 

 the stable. This stable must be perfectly ventilated. 

 The stable must be cleaned daily and manure hauled 

 away each day. By this you prevent germs, obnoxious 

 gases and flies. The drinking water provided must be 

 pure and uncontaminated. Care in food and regularity 

 in feeding must be exercised. Milking must be done 

 in regular hours and must be absolutely sanitary.
