Diseases Due to Mistakes in Feeding. 207 



horses from bolting the feed such as whole oats or from 

 hard physic balls, pieces of roots, pressure by the collar, 

 or the formation of abscesses in colt distemper (stran- 

 gles). In cattle the flow of saliva from the mouth, at- 

 tempts to cough, bloating and the presence of the obstruc- 

 tion somewhere along the course of the gullet indicate 

 the trouble; in horses the nose is poked out, the neck is 

 stiff, if attempts to drink are made the fluid is discharged 

 through the nostrils, slavering, anxious expression, diffi- 

 cult breathing, the horse may drop to the ground, and

The treatment in cattle is comparatively simple and 

 successful; the bloating is first relieved by tapping, an 

 oiled probang or piece of twisted rope is passed down the 

 gullet and endeavor made to push the obstacle on down, 

 a little oil poured down occasionally, or before the use 

 of the probang, is also useful, an assistant may also 

 gently try to work the obstruction downward if seen; do 

 not use a whipstock unless very flexible or a torn gullet 

 and death may result. 



In horses small doses of oil and water may be given, 

 providing the animals are given the head free so as to 

 avoid the material going the wrong way; if from the 

 collar remove and use one of the proper size and fit; the 

 veterinarian is almost indispensible in cases occurring in 

 horses, as chloroform may have to be given and an oper- 

 ation performed.

 errors in feeding, although it frequently occurs from 

 driving on hard dry roads, excessive purging, sudden 

 checking of sweating by giving very cold water when
