76 DISEASES OF CATTLE. 



ITCH. 



Itch is a disease of the skin and may be due to parasites or other causes. The 

 treatment is to wash the parts thoroughly with a sohition of Germ Killer, and apply 

 Skin Ointment according to directions, thoroughly rubbed in. The animal should 

 receive Cow Tonic according to directions to purify the blood and tone up the 

 system.

JOHNE'S DISEASE OR BACTERIAL DYSENTERY. 



Bacterial Dysentery is a slow, contagious cattle disease existing in the United 

 States for a number of years. The first case noticed by the writer came to his 

 attention some years ago. 



There is perhaps no disease whose outward appearance resembles tuberculosis 

 more than Bacterial Dysentery. There is the same continual and gradual wasting 

 away of the tissues until an animal, which was once in a healthy condition, becomes 

 a walking skeleton. 



There is always a looseness of the bowels, as the name of the disease would 

 indicate, and an animal is more apt to show rapid emaciation immediately after calv- 

 ing than at any other time. In fact, the period of calving is usually the starting 

 of Bacterial Dysentery. 



Past records show that this disease is more apt to afflict imported animals than 

 our own native cattle ; and the fact that a great many of the imported cattle are 

 afflicted shortly after being imported, would indicate that they were affected before 

 arriving in the United States, the disease developing after their arrival. 



If an animal is bred while in an advanced stage of this disease, conception is 

 not likely to occur ; but if she does conceive, in rare cases the fcetus may be carried 

 a few months, when it is liable to die (owing to the low vitality of the mother), 

 become mummified and be carried as long as the animal lives. The author has 

 witnessed a number of such cases. 



Owing to the fact that this is a contagious disease, it is advisable to remove 

 animals thus afflicted from the balance of the herd and thoroughly disinfect the 

 stables with Disinfectall. At the present writing there is no treatment known that 

 has proved successful in overcoming BacterLal Dysentery. 



This disease is not common, but does e.xist in the United States at the 

 present time. 



LEUCORRHOEA OR WHITES. 



Leucorrhcea or whites in cows is a catarrhal disease of the genital organs and is 

 usually brought on by infectious abortion or retention of the afterbirth. They will 

 he noticed to have a white or dirty discharge from the vulva, usually of an infectious 

 nature. 



Treatment. 



The animal should receive Breeding Tonic internally and the vagina should be 

 washed out with a solution of Antisepto until all discharges cease.

LEAD POISONING OF CATTLE. 



Lead poisoning of cattle is oftentimes mistaken for rabies or vice versa. It 

 usually comes from their having licked freshly painted mangers or buildings, and 

 thus swallowing compounds containing white lead. 



In several instances cattle have been poisoned by eating silage from a silo 

 painted inside with lead paint shortly before filling.
