DISEASES OF CATTLE. 919 



essentially the same in its nature, differing only in some of 

 its symptoms and in the manner of its attack. It is of the 

 nature of anthrax, yet it can be, and is, influenced by malarial 

 poisons, and is something akin to the yellow fever of man, 

 and yet it is not the same. It also very slightly resembles 

 rinderpest. 



It is spread by contagious influences. Texas cattle carry 

 and spread the poison in the road and pastures wherever they 

 go. The period which elapses from the time of exposure to the 

 disease and the time of taking it varies from two to five weeks. 

 Those that are slow in taking it, have it less violently, and 

 vice versa. A diseased animal may carry the contagion without 

 itself being much affected. An affected Northern animal can 

 not convey the poison or contagion to another native animal. 

 Infected animals, when taken North, lose the disease after a few 

 frosts in the fall ; cold stops it. 



An examination after death shows the spleen to be enlarged 

 and disorganized ; the mucous lining of the intestines softened 

 and greenish in color, which indicates mortification. The intes- 

 tines will be ulcerated, as in typhoid fever in man. 



SYMPTOMS. The first symptoms noticeable will be a rise in 

 the heat of the body ; the temperature will be 103 or 107 F. 

 Then the animal becomes dull, its back will be arched, its ears 

 hot, and its appetite lost. The cud is no longer chewed ; the 

 eyes become glassy; the muscles jerk, and the urine will be 

 dark colored black or bloody to which if nitric acid be added 

 it will become cloudy. The dung will be dry and bloody. The 

 animal dies in stupor or convulsions. Northern cattle taken 

 South are very liable to have this disease, and very seldom sur- 

 vive an attack. 



TREATMENT. Keep all diseased animals away from healthy 

 ones ; keep them warm and dry, for an animal so affected can 

 not withstand even a severe frost, and should be warmly sta- 

 bled and bedded.
