SECTION II 



Sanitation 



Where any considerable number of birds are 

 brought together on limited grounds, disease is 

 certain to appear among them sooner or later. 

 The greater the number of birds kept on any given 

 area, other things being equal, the sooner disease 

 will appear, the more rapidly will it spread, and 

 the greater will be the loss from it. 



All intelligently directed measures to prevent or 

 delay the appearanc of disease in a flock, all sane 

 measures to limit its spread and encompass its 

 eradication, constitute sanitation. Measures, the 

 purpose of which are to cure the sick birds or re- 

 lieve their suffering, come under the head of 

 therapeutics or therapy. 



On farms of considerable size, where attention 



is given chiefly to general crops, and but few fowls 



are kept on a practically unlimited range, the loss 



from disease may be small, where indifferent or 



even bad sanitation prevails; but in intensive 



poultry plants, where the number of birds is 



large for the size of the range, there can be no 



continued exemption from devastating epiorni- 



thics, if reasonable sanitation is not enforced. Any 



attenipt to operate such a plant in insanitary 



buildings and yards, or under conditions that do 



not permit of sanitation, while it may succeed for 



a time, will result in loss oftenerthan otherwise 



and, in the end, must inevitably fail.
