HORSES. 131 



There are other causes of thick wind. A horse unaccus- 

 tomed to exercise is thick-winded, because the lungs can- 

 not at once accommodate themselves to the full and deep 

 breathing which the exertion requires. A horse, under 

 exertion, on a full stomach, is thick-winded, as there is 

 not room for the lungs to expand freely. The practice 

 of grooms in galloping horses after drinking, is very 

 injurious, 



REMED-y . There is no cure for cases arising from the 

 obliteration of the cells in the lungs, and this shows the 

 importance of prompt attention to those diseases which 

 produce this complaint. Much may be done by good 

 management to relieve the animal, and fit him for ser- 

 vice. Give the food in small compass, feeding freely 

 with roots and grain, and sparingly with fodder. Feed 

 regular ; give water often ; give moderate exercise 

 work moderately and regularly ; but not on a full stom 

 ach. Let all the food be pure, and of a good quality 

 and cut and moisten the fodder. In this way, the con- 

 dition of the horse may be improved, so that he will do 

 good service. 



Broken Wind is sometimes caused by violent and pro- 

 iracted inflammation of the lungs ; it is also produced 

 by over- working a thick- winded horse ; but it is more 

 frequently caused by sudden exertion with a loaded 

 stomach, either from eating or drinking. It is owing to 

 a rupture of some of the cells of the lungs ; consequently 

 the air is readily admitted during the expansion of the 

 ungs, but in the expulsion of the air, it becomes en- 

 tangled in the ruptured cells, and is forced out with 

 great difficulty ; hence the in-breathing is naturally per- 

 formed by one effort, and the out-breathing by two, 

 occupying a longer time. 



Remedy. There is no cure. Much may be done to 

 alleviate. Pursue the course recommended for thick 

 wind. [See page 97.] 



Heaves. Although there is no remedy for severe 

 cases of heaves, yet horses may be so far relieved that 

 they may appear to be cured, while under good manage- 

 ment. We add several remedies, as they are regarded. 



Remedy. Two table spoonfuls of tar, mixed with the
