WORM PARASITES. 



Symptoms of the Disease. 



The symptoms of Gapes are very pronounced. 

 One of the chief features is the l yawning' or 

 ' gaping/ with widely opened beak and constant 

 straining forwards of the neck. In many birds,, 

 especially young ones, a w T heezing cough is notice- 

 able. When many worms are present, a frothy 

 saliva is often noticed in the mouth. The birds 

 become dull, and have a diminished appetite. The 

 feathers become erect, weakness increases, and death 

 may result unless remedies are adopted. 



Treatment and. Prevention of Gapes. 



One of the first steps to take is to isolate any 

 affected bird, so that others cannot eat the coughed- 

 up Syngami, as is too often done. 



The runs and houses after an outbreak should 

 always be disinfected. This is best performed by 

 watering the ground with a one-per-cent. solution of 

 sulphuric acid. 



By the addition of 3 drams of salicylate of soda to 

 every quart of drinking-water, the ova and embryos 

 are destroyed. In cases where the disease is very 

 prevalent, this may well be employed. 



The frequent removal of the birds from place 

 to place, dry, clean, and light houses and runs, will 

 greatly tend to lessen the chances of this parasite. 



As the ova of many, if not all, parasitic worms can 

 remain some time without undergoing development
