[Comparison of the effects of two walk-through footbaths on the prevalence of digital dermatitis and interdigital dermatitis on a commercial dairy farm].

This field trial was designed to evaluate the effect of treatment with copper chelate or formalin walk-through footbaths on the prevalence of digitalis dermatitis and interdigital dermatitis on a dairy farm. Although there was no difference in effect between the two types of footbath, the probability that interdigital dermatitis improved or remained stable was lower with the copper chelate footbath than with the formalin footbath.
