milk secretion will stop. The horns are hot and 

 the disease spreads rapidly to the other animals 

 of the same species. 



DISTEMPER Distemper (colt strangles) is a disease of 



young horses and is found in all parts of the 

 \Vest. It is probably more prevalent in the 

 spring time, it is an infectious disease. 



SYMPTOMS The colt appears to be feverish, stupid, does 



not eat well ; appears to be tired and draws great 

 quantities of water. In two or three days the 

 throat is found to be very sore and there is usu- 

 ally a swelling behind the angles of the jaws. 

 In two or three days more this swelling softens 

 and pus is discharged freely. If the disease 

 runs a normal course, the colt recovers within a 

 \veek or two. If it runs an irregular course, it 

 may mean the accumulation of pus in the gut- 

 tural pouches just below the ears on one or both 

 sides. There may be inflammation of the throat 

 that strangles the colt and makes breathing diffi- 

 cult. There is likely to be inflammation of the 

 lungs. Or, a bad diarrhoea may set in. One 

 of the worst complications shows itself two or 

 three weeks after the colt has apparently recov- 

 ered. A swelling will suddenly appear in some 

 unusual place on the body. Within a day or 

 two this will be found filled with pus ; soon other 

 abscesses will appear and the animal is in very 



bad shape.
