DISEASES OF HORSES AND CATTLE. 339 



horned by other cows; also by the udder being 

 over-distended with milk, either before or after 

 calving. When this organ is inflamed the inflam- 

 mation causes the milk in it to coagulate, separat- 

 ing into curds and whey. When the teats are 

 drawn, shreds of coagulated milk come away 

 mixed with whey. This curdled milk sometimes 

 stops up the orifice of the teat and allows nothing 

 to pass through it. This is a bad complication, 

 often destroying part or the whole of the udder. 

 It may arise from the animal being in too ple- 

 thoric a state, and being fed on sloppy food. It may 

 occur without any apparent cause. It is said hot 

 weather has a tendency to produce it. 



Symptoms of mammitis are increased heat, red- 

 ness, swelling and pain. As the swelling in- 

 creases it becomes hard and very tender to the 

 touch. The animal will show much distress if 

 made to move, and lameness in one or both hind 

 legs. When very much distended the animal will 

 be stiff and not inclined to move unless forced to 

 do so. In bad cases the animal will show consti- 

 tutional symptoms characterized by loss of appe- 

 tite, dry nose, quick pulse, seventy to eighty per 

 minute, labored breathing. Instead of milk com- 

 ing when the teats are drawn, a thin whey mixed 

 with curd. Later on the discharge becomes fetid 

 and thick. If the disease is not checked there is 

 a tendency for matter to form; when this takes 

 place the part will become white in color, and 

 pointing; this will break usually of its own ac- 

 cord, leaving a deep, ragged ulcer. Sometimes
