DISEASES OP THE DIGESTIVE TRACT 105 



Treatment. — Give intestinal antiseptics, sueli as one part 

 of carbolic acid to two hundred i)arts of water, or mercuric 

 chlorid (corrosive sublimate), one part to ten thousand parts 

 of water, or sulphocarholates compound. 



Immediate temporary relief may be given In' liberating? 

 the gas througli an aspii-ating needle or a small cannula. The 

 crop may then be irrigated, through the cannula, with a mild 

 antiseptic solution. Follow with two teaspoonfuls of castor 

 oil and feed sparingly on easily digested food. 



ENLARGED CROP 

 Pendulous Crop 



The crop may sometimes become very much enlarged, slack 

 and pendulous. This condition is mainly due to injudicious 

 feeding. 



Pendulant crop causes little inconvenience to the bird and 

 is incurable except by resection of a portion of its walls. 

 This operation is simple and easily performed. 



GANGRENE OF THE CROP 



This condition has been observed several times by the author. 

 It resulted fatally to the birds affected in all the cases studied. 

 Upon opening the crop a very offensive odor is noted, the 

 mucous lining will be found in a necrotic state (sloughing) 

 and appear as a dark, sometimes a greenish, caseous mass. 



Treatment. — In the earlier stages there may be given, in the 

 feed or water, salol, subnitrate of bismuth or sulphocarholates 

 compound. If the condition becomes prevalent in a flock, the 

 runs, yards and henhouses should be thoroughly disinfected 

 or the birds completely changed to new grounds, and in any 

 case given clean food and drink. The sick should be separ- 

 ated from the well birds and the dead should be burned. 



CATARRH OF THE CROP (INGLUVITIS) 



Irregular feeding, a distended crop and irritating and in- 

 digestible feed, such as feathers, putrid meat and irritant 

 chemicals, may be mentioned as causes of this condition which 

 is essentially a more or less chronic inflannnation of the mu- 

 cous meml)rane, lining the crop. If the crop be over-distended 

 the strain on the muscles may be so great that paralysis re- 

 sults. In these cases there is noted a crop tilled with a pulpy, 

 soft, more or less gaseous mass. 



It may be noted after the ingestion of pointed objects. 

 Too early removal of the squabs from the parent birds (pig- 

 eons) has been known to cause ingluvitis because of the fact
