containing this parasite or its eggs, and by coming in 

 contact with other birds suffering from the disease. 



Symptoms : The most noticeable symptom is frequent 

 gaping; the Gapeworms attach themselves by their 

 mouths to the walls of the windpipe where they suck the 

 blood which nourishes them; they cause irritation and 

 inflammation of the windpipe, bronchial tubes and lungs ; 

 breathing is difficult and the bird loses strength rapidly; 

 windpipe eventually becomes totally obstructed and the 

 bird dies from suffocation and exhaustion. Young, weak 

 chickens are more susceptible to this disease than strong 

 ones. 



y"' Treatment : Separate the sick birds from the healthy 

 ones. Clean and disinfect the coops and runs. Burn all 

 ' manure. Eemove the worms from the windpipe by the 

 use of a feather, from which the fan has been stripped, 

 leaving only a small brush at the end. Dip the feather 

 into Oil of Turpentine or Coal Oil, removing the surplus 

 liquid by drawing the feather between the fingers. Now 

 insert the feather into the windpipe of the bird and by 

 turning gently you will dislodge the worms from their 

 attachments. Eepeat this treatment once a day for two 

 or three days. Disinfect coops and runs with undiluted 

 Crude Carbolic Acid. Feed good nutritious food as 

 wheat bran mashes, etc.

Cause: Result of insanitary conditions and lack of 

 care. Communicated by direct contact with infected

 the feet. If not properly treated the chicks weaken and
