III. Contagious Fever of Swine. 



This is sometimes called intestinal hog cholera. 



Causes. — It is contagious and the infection is virulent, so much so that 

 tiie germs arc carried to considerable distances, supposablyin the air. If 

 not generated in foul pens and yards, they, together witi: bad care and 

 management, cause it to develop quickly when the germs are once intro- 

 duced. 



How to know it. — Succeeding the incubation, which lasts from three 

 days to two weeks, according to the season and temperature, there will 

 be shivering ; prostration ; the nose hot and dry ; the animal mhU not 

 feed, but will lie under the litter ; the eyes will be sunken ; the gait weak 

 and unsteady. There will be great thirst, and a clinical thermometer in- 

 s:'erted into the rectum will show a temperature of 103 ^ to 105 <^ F. 

 There will be heat and soreness of the skin, with red patches and black 

 spots, the redness disappearing under pressure. The pulse will be weak 

 but rapid ; the tongue much furred ; a hard dry cough, and quick breath- 

 ing ; the belly is sore and the animal will flinch and scream if it is 

 handled ; the l)owels are costive sometimes throughout the disease, but 

 generally as the disease progresses, or about the third day, diarrhoea, 

 foetid and exhausting, will supervene, and slime and blood may be passed, 

 showing ulceration of the bowels. The last stage occasions stupor, par- 

 alysis of the hind limbs, with tremblings, jerking of the limbs and invol- 

 untary motions of the bowels.
