Laryngitis in Sheep. 123 



noise in breathing is the predominant S5'mptom and sometimes 

 almost the only one. 



Course, etc. The cough and other symptoms are usually mod- 

 erated with the access of the abundant secretion on the second or 

 third day, and recovery is perfect on the eighth to the fifteenth. 

 If abscess results, to which there is a far greater liability than in 

 the horse, it may not burst till the twentieth day and the case is 

 correspondingly protracted. This should be carefully distin- 

 guished from the deposits of tubercle which take place around 

 the throat. in cattle. In rare cases the disease becomes chronic. 



Treatment does not differ from that advised for the horse ex- 

 cept in the greater safety of purgatives which must in this case 

 be saline (Epsom or glauber salts one to two pounds), and in the 

 greater ease with which local treatment can be applied owing to 

 the shortness of the soft palate. When abscess forms it must be 

 encouraged by poulticing and opened with the knife or lancet as 

 soon as it points. 



LARYNGITIS IN SHEEP. 



Infrequency. Causes, damp lands, storms, close buildings, clipping. 

 Symptoms, cough, sneezing, discharge, snuffling, oral breathing, tender 

 throat. Treatment, ventilation, warm water vapor, sulphur dioxide, salines. 



Sore throat is fortunately even more rare than in the larger 

 ruminants. It occurs chiefly where this animal, constituted to 

 feed on the dainty grasses of the dry mountain side, is kept on 

 cold, marshy ground and exposed to frequent cold, wet blasts. 

 Sheep suffer also from hot, close, filthy buildings in winter, and 

 from unseasonable clipping. 



The symptoms are frequent coughing and sneezing, running 

 from the nose, working of the jaws, and breathing through, the 

 open mouth as being easier than through the plugged nostrils. 

 The larynx is tender and may be swollen. 



Treatment is usually confined to ventilation and cleansing of 

 the fold, frequent fumigations with water vapor from the spout 

 of a boiling kettle, and with sulphur fumes, and giving tepid 

 farinaceous gruels or mashes containing sulphate of soda in the 

 daily proportion of two pounds to each hundred head of sheep. 

 Sal ammoniac may be given in food or drinking water.
