Ringworm on Cattle
Ringworm on Human – the “ring” is more noticeable

Calves, and sometimes cows, break out with round scabby sores caused by the fungus “ringworm”.

Treating Ringworm

  • Fungus thrives in wet, dark places. All that is needed for treatment is DRY & AIRY solutions.
  • Wear gloves!
  • Remove the scab forming over the top of the ringworm by scraping with a curry comb or a stiff bristle brush (an old toothbrush, for example – throw away once done treating).
  • Scrub the exposed wound with a rag soaked in diluted iodine (dilute iodine until it’s the color of iced tea). The wound will bleed – this is GOOD.
  • Ample sunshine and fresh air help substantially (shots of Vit A & D can help as well).
  • Repeat as needed. Usually 2-3 times for the full protocol should be sufficient. You know you’re on the mend when the scab stops forming in a thick crust and eventually the edges shrink & hair regrows.

A note: When we housed our dairy heifers inside a barn without access to pasture or outdoor lots, they almost always came down with ringworm. Now, our heifers are housed either outdoors (in wooded lots) or in freestall housing with access to pasture or dry lot. Knock on wood, we haven’t had a case of ringworm in over 4 years…
