ULCERS OF THE STOMACH AND INTESTINE. 185- 



COLICS OP THE PIG. 



Etiology and symptoms. Colics of the pig are ordinarily due 

 to overloading through heavy food of bad quality ; also through 

 bran, fermentable food, such as malt, etc. Colics may also be pro- 

 duced through colds, intestinal worms — especially through the 

 Ascai'is lumhricoides and the giant Echinorrhynchus. Phlegmasia of 

 the stomach and intestiue, aud the invaginations, which are quite 

 frequent in the pig, are also accompanied by colic. 



The animals are restless aud agitated ; they refuse their food, lie 

 dowu, complain, and cry with the pain. They often stretch them- 

 selves upon the ground, aud are affected with convulsions and 

 tetanic attacks. 



Treatment. We must administer purgatives and quieting elect- 

 uaries, give injections, and make repeated dry frictions upon the 

 abdomen. The patients will have to be placed in a warm place 

 covered with an abundant litter. 



ULCERS OP THE STOMACH AND INTESTINE. 



In our domestic animals ulcers of the stomach aud intestine 

 rarely constitute any essential lesions independent of other acute 

 affections. They are most frequently developed during the course 

 of certain diseases (hydrophobia, bovine pest, petechial fever, dysen- 

 tery, gastro-enteritis, and gastro-intestinal catarrh) ; in some cases 

 they are caused by foreign bodies or by parasites (gastrophile 

 larvae, spiroptera, etc.); finally, they are observed in poisoning by 

 irritating or caustic substances. Considered from their pathological 



felt a lengthy tumor, measuring from ten to twelve centimetres in length, which was 

 movable in all directions, and of such sensibility to exploration, even when practised 

 delicately, as to evoke cries of pain. Biot diagnosticated invagination, and decided 

 to operate immediately. He performed laparotomy upon the left side, and with the 

 right index finger brought out an invagination of the small intestine, the circum- 

 ference of which was seventeen centimetres. The reduction could not be obtained by 

 traction upon the invaginated part ; there were some adhesions which had to be sev- 

 ered with the bistoury. There was but a slight hemorrhage, which soon stopped. 

 The intestine was put back into the abdomen, and the lips of the flank wound brought 

 together with a cross stitch, which was covered up with a slight emplastic coating of 

 melted pitch. From the third day the wound was in an excellent condition for cica- 

 trization, and the recovery was complete within a couple of weeks ( Recueil Vét.,
