26 SPECIAL CATTLE THERAPY 



advising against direct interference with the trouble 

 by medical means. If the condition should persist 

 after the parturition we would advise a course of po-

EPISTAXSIS 



Nfisal hemorrhage can occur in cattle as the result 

 of injuries and contusions under the same circum- 

 stances that it occurs in other animals. 



The particular form of epistaxsis which we will 

 discuss here is that form which occurs now and then 

 in cows during the period of gestation, and not as the 

 result of trauma. 



The cows which are the subjects of a hemorrhage 

 of this nature are generally aged cows in somewhat 

 unthrifty condition. 



They are most frequently affected during the lat- 

 ter period of pregnancy, usually when about four to 

 six weeks before calving. The symptoms are pre- 

 cipitated by a somewhat profuse flow of blood from 

 one or both nostrils, amounting on occasions to sev- 

 eral pints. 



The flow stops of its own accord in most cases, after 

 a few hours. The cow is off feed for a day or two and 

 nothing further of note follows. After five or six 

 days, sometimes a week or ten days, the hemorrhage 

 recurs, leaving the cow usually in a dejected, weak 

 condition. Three or four such hemorrhages may 

 occur before the close of gestation, after which they 

 do not oeour again. Evidently the jiregnant slate is 

 lespoiisible for the condition in some niannei-, it be- 

 ing distinctly a disease of pregnanc.v. 



If the hemorrhages are severe eiKuigli and recur at 

 short intervals, the cow is in poor condition to sur-
