infectant applied. In cattle the best remedy is pine tar 

 held in place by a bandage passed between the claws and 

 tied around the pastern. 



HEMORRHAGIC SEPTICEMIA. This disease runs a short 

 course in cattle that frequently ends in death and affects 

 calves more commonly than older animals. The method 

 of infection is not known although cattle on pasture are 

 less likely to be affected than those under confinement. 

 The animals refuse feed, exhibit a severe fever, show 

 difficulty in breathing and develop swellings in the throat 

 and brisket. When the intestines are affected the animals 

 show signs of colic and pass bloody manure. Once the 

 disease is developed medicines are useless, hence efforts 

 are directed toward preventing the spread to other 

 animals. All unaffected animals should be removed to 

 fresh quarters and vaccinated, and the infected buildings 

 and lots disinfected. 



TUBERCULOSIS. This is one of the most serious diseases 

 affecting cattle because of the possibility of its transmis- 

 sion to man. It is readily transmitted to hogs following 

 cattle, in many cases as high as 25 percent being rendered 

 unfit for food. The disease is so named because small 

 tubercles form in the internal organs. Infection is 

 ususally spread by eating food or drinking fluids con- 

 taminated by the discharges from infected animals. 

 Frequently animals severely afflicted with the disease 

 show no signs of it externally. If the lungs are affected 

 there may be a cough and difficulty in breathing, while 

 if the intestines are involved, a chronic diarrhea is present. 

 The common test for the presence of tuberculosis is the 

 injection test with tuberculin. The animal shows a 

 marked rise in temperature a few hours after injection if 

 affected with the disease. There are also tests used 

 known as the eye test and the tail test. The former, or 

 opthalmic test, consists of placing a small disc or tablet 

 of concentrated tuberculin under the upper lid of the eye
