SECTION IX 



Disease of the Ovary and 

 Oviduct 



Prolapse or Eversion of the Oviduct 



This is a common ailment of laying hens. Over- 

 feeding and aggravated constipation have been 

 found associated with this condition. When the 

 eggs are large and considerable straining takes 

 place during their passage, and in inflammation 

 of the mucous lining of the oviduct or egg canal 

 prolapse or a protruding of the mucous membrane 

 through the cloaca may be observed. In consti- 

 pation, the bowels becoming gorged, and this in 

 addition to the obstruction when the egg canal 

 contains one or more developing eggs, and the 

 ovary, being active, is larger and adds to the bulk, 

 predisposes to prolapse. 



This condition is most often seen in hens that 

 are heavy layers. It perhaps occurs most often in 

 old hens. If the prolapsed or protrduing mucous 

 membrane is allowed to extend through the anus, 

 it soon becomes inflammed from exposure to the 

 air and infection (germs). Later the parts may 

 become ulcerated as a result of mechanical injur- 

 ies or the attack of germs. 



Treatment.— Wash off the accumulated material 

 on the vent feathers with clean, soapy, warm 

 water. After cleansing the hands, replace the 

 protruding mass, using on the fingers carbolized 

 vaseline, three to five per cent strength. Keep 

 the hens on a light diet for several days so that
