114 DISEASES OF THE STOMACH AND BOWELS 



Oxyuris curvula, the whip-worm of the horse, which 

 produces proctitis. 



The larvse of Gastrophilus equi and pecorum rarely produce 

 colic. In exceptional cases in colts they may induce traumatic 

 gastritis or, by perforating the stomach wall, peritonitis. 



Treatment. — Through the use of purges alone intestinal 

 worms cannot always be removed. 1 The most valuable 

 agent for their removal in horses is tartar emetic (3ij to 

 Bss) daily; given in drinking water two or three times. 

 Besides arecanut (Siij), arsenic (gr. xv-xxx in form of 

 boli), santonin (5 iiss) and turpentine oil (Biss-giij) may be 

 used. For gastrus larvae in the stomach bisulphide of carbon 

 (3 iiss) given at night in capsules, four capsules given one 

 hour apart. Follow with linseed oil (Oj). 



Flatulent Colic. — In some cases of simple impaction or in 

 impaction complicated with displacement an abnormal 

 fermentation of the bowel contents results. The gas (CO2, 

 CH4, H, air) formed leads to a distention of the abdominal 

 wall. It is more rarely due to "wind 'sucking." 



Symptoms. — The symptoms are those of simple or compli- 

 cated impaction with great distention of the abdominal wall, 

 and from compression of the diaphragm, severe dyspnea. 



Treatment. — The treatment consists in using the trocar 

 either through the side (cecum) or more rarely through the 

 rectum. If the stomach is bloated the stomach-tube should 

 be used. 



GASTRO-INTESTINAL CATARRH OF THE OX. 



Indigestion of Cattle. 



Definition. — Gastro-intestinal catarrh of the ox is an inflam- 

 mation of the mucous membrane of the stomach and bowels. 

 As the superficial layers of the mucosa of the rumen are 

 provided with a horny epithelium and the organ is probably 

 glandless, it offers remarkable resistance to the causes of 

 inflammation. Most of the disturbances of the rumen are 



'According to Udall and Albrecht aloes alone is an efficient agent to 

 expel intestinal worms in horses.
