Daring recovery and in the convalescent animal the diet should 

 be laxative and non-stimulating. Bran mashes, turnips, beets, 

 carrots, green fodder, ensilage and scalded hay may be allowed. 

 Oats, corn, beans, peas, vetches, etc., must be carefully avoided. 

 If the food fails to maintain the bowels in a gently relaxed con- 

 dition one, two or more ounces of sulphate of soda may be added 

 daily. 



In the mild cases a good dose of purgative medicine succeeded 

 by a course of diuretics will serve a good purpose. 



In all cases alike work must be resumed very gradually. At 

 first the animal may be walked a few hundred yards, and the 

 pace or load and duration of exercise may be increased day by day 

 until full work can be safel)^ endured. In an animal that has 

 once suffered the same gradual inuring to labor should be 

 followed, after any short period of rest on a fairly good ration.
