60 DISEASES OF THE HOG. 



tumors, and in some cases organized bands across 

 the bowel, originating likely from the process of 

 inflammatory adhesions of the surface of the mu- 

 cous membrane in consequence of the exudation 

 of coagulated lymph and a subsequent separation 

 of these surfaces, before the lymph has become 

 quite consolidated, so that it is drawn out in ap- 

 parently interlacing cords. Twisting of the bowel 

 is still another cause of obstruction, invagination 

 of the bowel is a frequent cause, strangulation by 

 the passing of a portion of the bowel through a 

 rent in the diaphragm, mesentery, etc. 



Symptoms of obstructions: It may come on sud- 

 denly, and in such cases there is great restlessness, 

 vomiting, straining to pass feces, with the effect 

 that the abdomen will swell and the animal show 

 all signs of inflammation and soon die. In other 

 cases it comes on slowly, the animal strains but 

 cannot pass feces; this continues in spite of purga- 

 tives and gradually goes on until the pig dies in 

 great agony. 



Treatment: Find the cause if possible but this 

 is usually not easily done in the pig. First give 

 a dose of castor oil and if this takes no effect give 

 salts and senna or two ounces of castor oil and 

 three drops of croton oil. When the pain is severe 

 give one grain of opium at a dose every two hours 

 or one grain of opium and half a grain of calomel 

 every two hours. Injections of soap and warm 

 water should be given every hour. If the vomit- 

 ing is severe give a drop or two of wine of ipecac. 

 Physostigmine in doses of one-tenth of a grain and
