RINGWORM 



Cause: Due to a vegetable parasite. It affects the 

 hair and the outer layer of skin and is highly contagious, 

 being transmitted from one animal to another. 



Symptoms: The disease usually appears in the form 

 of circular patches of the skin, which soon become denude 

 of hair. Sometimes a white sticky discharge and the 

 formation of scaly, brittle crusts on the patches appear, 

 silvery gray in color. They are generally confined to 

 the head and neck. It is a common disease among young 

 cattle in the Winter and Spring. This disease is at- 

 tended with more or less itching and is communicable 

 to man. 



Treatment: Bemove the scabs or crusts with soap 

 and warm water. However, the surface of the body 

 should be well dried after washing each time. Apply 

 Tincture of Iodine with a camel-hair brush to the spots 

 denuded of hair. It is quite necessary that the barn and 

 rubbing posts be disinfected by spraying or washing 

 them with a twenty-five per cent solution of Carbolic 



Acid. 



ROUND WORM 



Cause : An animal swallowing the eggs of the parasite 

 in food or water which has been contaminated with the 

 feces of infected cattle. There are two species, the large 

 Eoundworm measuring from five to fourteen inches in 

 length, the other small Eoundworm varying in size 

 from one-quarter of an inch to two inches in length. Both 

 the small and large Eoundworms infest the intestines 

 of cattle and calves. These worms, especially small 

 Eoundworms, irritate the mucous lining of the intes- 

 tines, which may cause severe inflammation. 



Symptoms: Anemia, appetite variable, diarrhoea,
