DISEASES AND PESTS OF FOWLS 

 ANAEMIA, OR GOING LIGHT 



A condition that should incite the poultryman to investigate 

 the cause 



Symptoms. Birds lose weight, or "go 

 light," without any apparent reason. 



Cause. A general lack of thriftiness in 

 the flock may be due to insufficient or poor 

 food, to lack of exercise, or to bad ventilation 

 of houses; lice or mites may be infesting the 

 birds. On the other hand, birds may gradu- 

 ally lose weight as the result of some such 

 disease as tuberculosis (see page 90, as- 

 pergillosis (see page 29), or worms (see 

 page 94) . 



Treatment. Make any changes in feed- 

 ing or management that may appear desir- 

 able. Search at night for mites or lice on 

 the birds; in the daytime examine the 

 straw in nest boxes, the roosts, and the 

 cracks and crevices of the woodwork for 

 parasites. Much time may often be saved 

 in discovering what is wrong with the flock 

 by killing one or more of the affected birds
