CYCLOPEDIA OF LIVE STOCK AND COMPLETE STOCK DOCTOB, 



p:ffect of laryngitis. 



A horse trying to drink, the water returning by 

 the nose. 



Causes. — Exposure to cold winds and storms, standing in drafts when 

 warm, nes^lect when cominjj in when warm from work, and extension of 



catai'rh from the nose. The cause of 

 roaring is chronic iniiammation of 

 the mucous membrane lining the lar- 

 }Mix, diminishing the air passage so 

 that when he is unable to get suffi- 

 cient air, and forcing it through the 

 small i)assage, makes the noise. 



How to know it. — The throat is 

 usually swollen on the outside, but 

 sometimes only on the inside, and is 

 tender upon pressure ; the nose is 

 protruded ; he has great difficulty in 

 swallowing, and often , when drinking, 

 the water will come back through the 

 nose nearly as fast as it goes into the 

 mouth, and what is swallowed is forced down with an effort. There is 

 usually a short, painful, subdued cough, dry at first, but getting more 

 moist after a couple of days. 



What to do.— Clothe warmly ; shelter from cold storms and drafts ; 

 rub mustard paste well into the throat on each side, well up towards the 

 ears ; feed on soft mashes, boiled oats, etc., and set a pail of water in the 

 manger for him to play in to cool the throat and mouth. Give internally 

 fever mixture No. 4, every two hours till the fever is reduced and the pulse 

 lowered ; then drop off to three or four times a day. If the swelling in 

 the throat does not yield to the above treatment, apply a soft, hot linseed 

 poultice to it, and change it once a day for a fresh one. The loss of 

 appetite, or rather inability to eat, will soon disappear and recovery will 

 be rapid. 



In case of roaring, apply a smart blister of cantharides, No. 9, to the 

 throat, and after three weeks repeat it. Inject a tablespoonful of the 

 mixture No. 35, three times a day well back into the throat, and let the 

 horse run at grass or feed on very soft food. 



Bad, long standing cases of roaring are incurable. Whistling is similar 

 to rearing, except in the noise produced ; it is subject to the same causes 

 and treatment. 



Roaring and whistling are sometimes, but very rarely, the effect of 

 paralysis of the nerves of the larynx, letting one or more of the cartilages 

 drop into the box to a certain extent, and thereby diminishing the caliber 

 of the air passage. Sometimes a small portion of the cartilage doing the 

 damage can be removed, but it requires the skill of a qualified veteri- 

 nary surgeon.
