A hairy hoof problem
A clean environment, adequate cow comfort and footbath use all bolster your ability to prevent digital dermatitis.

Lameness affects everything a cow does. Feed intake, fertility, milk production and, in the end, profitability are all depressed when an animal has sore feet. Digital dermatitis is a prevalent and sometimes painful hoof lesion that develops when the hoof skin barrier weakens and Treponema species are able to invade it.
According to Dörte Döpfer, at the University of Wisconsin-Madison, digital dermatitis is characterized by a raw, bright red or black circular erosion and inflammation of the skin above the heel bulbs. The edges of the lesion develop a white margin and overlong hairs that surround the sores or are adjacent to thick, hairy wart-like growths.
