HEAVES 229 



restricted to much less than is usually fed. Horses that are 

 greedy feeders should be bedded with sawdust or shavings or 

 protected by a muzzle in case other bedding is used. 



Autopsy. — On examination post mortem, the lungs may be 

 found to be somewhat bloated and to contain more air than 

 normal. The chambers in the right side of the heart are apt to 

 be enlarged and their walls tliickened. In examining the lungs 

 of long-standing cases of heaves, we note that they are pale and 

 tloat abnormally high in water, due to the emphysema or air 

 in the tissues previously mentioned. The stomach is often larger 

 than normal, due to the overeating of bulky foods and conse- 

 quent stretching. 



Treatment. — In cases of heaves avoid overripe and dusty hay. 

 Allow little bulky food of any kind. Give a small quantity of 

 hay for the morning feed, none at noon, and a very moderate 

 amount in the evening — much less than would be considered care- 

 ful feeding for a healthy horse. If the hay or grain is dusty, 

 sprinkle it as a regular custom. Use such horses for slow work, 

 and give as much rest as possible after meals. 



A month or two of this management will very greatly improve 

 most cases. 



]\Iedical treatment is considered unsatisfactory so far as cura- 

 tive effect in bad cases is concerned. Fowler's solution in one- 

 ounce doses three times a day in the feed, long continued and 

 coupled with careful feeding, is often a great help. Proper 

 feeding alone may be said to be almost curative, although sub- 

 sequent attacks are easily brought on by injudicious manage- 

 ment.
