378 Impaction in the Intestines of Rabbits. 



cathartics should be introduced into the stomach by the aid of 

 the stomacli tube (tartar emetic 0.5-1.0 gm., castor oil 50-100 

 gm,, dissolved in water or mixed with it), or eserine (0.005-0.02 

 gm.) given subcutaneously. Tartar emetic, castor oil or calomel 

 may be given in the shape of an electuary. Dietetic treatment 

 consists in feeding bulbs, fallen fruits, green feed, cut pumpkin, 

 sour milk or whey.

(e) Impaction in the Intestines of Rabbits. 



Etiology. Rabbits develop impaction of the large intestine 

 after too almndant or exclusive dry feeding, particularly after 

 dry bran or undigestible food stuffs have been given continu- 

 ously. 



Secondary impaction occurs after chronic intestinal catarrh 

 in the presence of enteroliths and sometimes in consequence of 

 painful affections of the rectum or of the parts in the region of 

 the anus. 



Symptoms. There is at first retarded defecation, then com- 

 plete constipation, diminution of appetite and listlessness. Pal- 

 pation of the abdomen, which is very easy, reveals the presence 

 of desiccated masses of feces in the large intestines. 



If proper treatment is instituted early the disease ends 

 in recovery. 



Treatment. Repeated rectal injections of water, and soaj) 

 suppositories are to be employed (from tea to table spoonful 

 doses). Syrup with milk in equal parts, pills of the leaves of 

 senna (1-2.0 gm.) or of rheum (0.2-0.4 gm.). Tincture of rheum 

 (5-10 drops in water), also root of jalap (0.2-0.3 gm.), or calo- 

 mel (0.05-0.2 gm.) may likewise be used. 



The diet should consist in green feed, juicy roots, lettuce, 

 etc.

(f ) Impaction in the Intestines of Fowls. 



Etiology. The disease is rare in domestic fowls which are 

 kept in the open air; if it occurs at all it is generally due to 

 foreign bodies (pebbles, feathers, animal parasites, pieces of 

 rags). More frequently, although still rarely, the disease is seen 

 in over-fed, highly bred fowls kept in confinement in cages, or 

 in house birds. These animals suffer from a combination of 

 heavy undigestible feed and sluggish peristalsis. Impaction in 

 the cecum, due to improper feeding, appears in enzootic form, 

 particularly among young turkeys. The matting together of
