mended. The calf's ration of milk should be reduced one-half, 

 and in cases where the milk does not agree with the affected 

 animal, barley gruel to which raw eggs are added, may be 

 substituted. A mild solution of formalin, which is mixed with 

 the milk, is quite efficacious for the treatment of this disease. 



EINGWOEM (bald SCAb) 



Ringworm is a highly contagious, transmissible disease of 

 the skin caused by a vegetable parasite (Tinea Tonsurans). 

 This disease affects the root and shaft of the hair, causing it to 

 become brittle and finally fall out. Calves are commonly 

 affected, especially during winter and spring. 



Ringworm is communicable to man. 



Symptoms. — ^Ringworm is manifested by the formation of 

 circular hairless patches, on the skin of the head, neck and 

 extremities. The patches vary in size, some being about the 

 size of a pea, while others will measure an inch or more across. 

 The patches or spots are usually scattered, although they may 

 run together, forming large ones. The skin becomes slightly 

 inflamed and the exudate, which is of a sticky nature, forms 

 dry, brittle and scaly crusts of a greyish color. Occasionally 

 the entire skin of the body will become affected, which may result 

 in complete nakedness. In sucking calves the patches form 

 mainly around the mouth. The disease is attended by itching 

 which is manifested by rubbing in the affected animal. Any 

 animal so affected is uncomfortable, restless and does poorly. 



Treatment. — Preventive measures consist of removal of 

 affected animals, cleaning and disinfection of stalls. The 

 affected patches or spots should be washed with soap and water 

 so as to remove all crusts and after drying, tincture of iodine 

 may be applied by painting the diseased areas. The treatment 

 may be applied once daily. If attended to faithfully recovery 

 should be complete in four to six weeks.
