DISEASES AND PESTS OF FOWLS 



acts partly as an emetic, causing the fowl 

 to make an effort to vomit. In cases of 

 mineral poisons, post-mortem examinations 

 show inflammation of the stomach and the 

 digestive tract. 



Sources of poison. Poultry are likely to 

 get poisoned from the following sources : 



Fertilizers (e. g., nitrate of soda) used 

 on fields in which fowls scratch for food. 

 Such cases are rare. 



Insecticides and fungicides (e. g., Paris 

 green [arsenic], lead arsenate, Bordeaux 

 mixture) applied to plants under which 

 fowls run. If sprays are mixed in correct 

 proportions and used in normal quantities, 

 there is little danger to poultry feeding on 

 the grass below sprayed trees. Great care 

 should, however, be taken in disposing of 

 the sediment and the residue after spraying 

 operations are completed. 



Rat poisons (e. g., phosphorus, strych- 

 nine, baryta). These poisons are particu- 

 larly dangerous when mixed with cornmeal 

 or other bait attractive to fowls. The best 

 way to set rat poison is to put it in a piece
