178 DISEASES OF SWINE 



(4) While appetite is lost, there is a marked thirst, which becomes 

 greater as the disease progresses. 



(5) Temperature goes up very rapidly, and the animal has sev- 

 eral degrees of fever within a short time after the disease starts. 

 Temperature may run up to 106° or 108° F. and even higher. 



(6) Skin is dry and hot at first. Later on it becomes covered 

 with a sticky, black-colored, grease-Uke fluid which is poured out 

 by the glands of the skin. 



(7) Scarlet-red flushing and bluish-red blotches make their 

 appearance on the skin, especially around the ears, on the snout, 

 chest, inner side of the forelegs, flanks, and along the under sur- 

 face of the belly These red spots are more easily seen in white 

 hogs than in the black-colored breeds. 



(8) Ears, in addition to being red, are swollen and often 

 covered with bUsters and small sores. These sores are especially 

 hkely to form in hot weather, when the blisters become poisoned 

 from the bites of flies. 



(9) Sick animals are at first constipated. Later begin to scour 

 freely, and develop a very stinking, profuse, black diarrhea. This 

 diarrheal discharge soils the skin of the hams and around the tail. 



(10) When aroused from the litter of the sleeping pens and 

 forced to move about, the sick animal starts to cough. This cough 

 is of a peculiar dry, forced, hacking nature. 



(11) Animal stands with the back arched and the flanks drawn 

 up in a gaunted position. 



(12) Sick animals lose weight very rapidly, and this increases 

 the gaunted or runty appearance of the sick hog. 



(13) Animals develop very marked weakness in the muscles, 

 especially the muscles of the hind legs. This weakness makes it 

 very hard for them to get up or to walk. 



(14) Hogs sick with cholera have a pecuUar staggering walk. 

 They especially stagger with the hind legs. In some cases the 

 weakness of the muscles and the swelUng of the eyes combined 

 produce a condition very much like blind staggers. 



(15) Eyehds are swollen, and there is redness of the inner side 

 of the eyehd, with a thick, yellow-colored, matter-Uke discharge. 

 This often glues the eyeUds together and adds to the blindness and 

 staggering gait when the animal tries to walk.
