INTRODUCTIONDigital dermatitis (DD) is a widespread infectious foot lesion in cattle that typically causes painful ulcerative lesions (Cheli and Mortellaro, 1974; Read and Walker, 1998).

INTRODUCTIONLameness is a severe welfare problem in cattle and has a detrimental effect on longevity (Cramer et al., 2009a), productivity (Green et al., 2002), and reproductive performance (Barkema et al., 1994; Garbarino et al., 2004). Consequently, it is among disorders causing the largest economic losses in the dairy industry (Ettema and Ostergaard, 2006). Approximately 90% of the causes of lam ...
