DISEASES AND PESTS OF FOWLS 



known at present are very much the same. 



Symptoms. There are no definite ex- 

 ternal symptoms. The poultryman's sus- 

 picions should, however, be aroused if fowls 

 apparently in good health die suddenly. A 

 post-mortem examination will reveal a liver 

 of abnormal size, or somewhat shrunken, 

 and of unhealthy texture. 



Cause. The cause is generally something 

 wrong in the feeding. Fowls may be eat- 

 ing too large a proportion of heat-produc- 

 ing foods and not enough green food. If 

 an enlarged liver is associated with an ex- 

 cessive layer of fat covering the internal 

 organs, it points to too large quantities of 

 carbohydrates. 



Treatment. Correct errors in feeding. 

 Give more green food and let the fowls 

 scratch for some of their grain. If errors 

 in feeding and general management are not 

 obvious, make experimental changes. 



Diseased Livers Due to Specific Diseases 



Tuberculosis, coccidiosis, gout and other 

 specific diseases are responsible for spotted
