226 SWINE DISEASES 



bacilli. In making this test it must be remembered that 

 there are other acid-fast bacteria and further that the 

 absence of tubercle bacilli in the preparations examined 

 is not positive proof of the absence of the disease. 



Animal inoculations may be resorted to, particularly in 

 cases in which no tuberculin test has been made and there 

 is a dispute as to the nature of the lesions found. 



Treatment. Curative treatment is of no value in 

 porcine tuberculosis. The only rational method is to 

 sell the affected swine subject to the post-mortem inspec- 

 tion findings. In this way some value will be obtained 

 by the original owner, there will be no loss to the packer, 

 and no danger to the consumer. 



Tuberculosis is a preventable disease and the losses 

 from it could be avoided, or at least materially dimin- 

 ished, by proper control of tuberculosis in cattle. With 

 our present farm methods the eradication of porcine 

 tuberculosis cannot be accomplished until the disease 

 is eradicated in cattle. The judicious use of skimmed 

 milk, including pasteurizing milk from suspected cows, will 

 materially diminish tuberculosis in milk-fed swine. 

 The tuberculin testing of steers or other cattle and the 

 elimination of all reactors will prevent the introduction 

 of tuberculosis in swine that follow cattle in the feed lots. 

 Cooking of garbage will prevent the dissemination of 

 tuberculosis to swine. Denver garbage is cooked and 

 fed to swine, the infection of tuberculosis and hog 

 cholera as well is thus eliminated. 



OMPHALOPHLEBITIS, PYEMIC ARTHRITIS 

 (NAVEL ILL) 



This is an acute infectious disease of recently farrowed 

 pigs characterized by inflammation of the umbilical 

 tissues and suppurative arthritis. 



Navel or joint ill has prevailed more or less extensively 

 since the dawn of history. In some years this disease is 

 responsible for the loss of a large percentage of the young 

 pigs produced in certain communities. The disease
