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
