Description
Investigations on the efficacy of herd-specific vaccines against digital dermatitis of cattle. The efficacy of two herd-specific inactivated vaccines against digital dermatitis (DD) was evaluated in a controlled study involving 429 cattle of a dairy farm in northern Germany. The vaccines contained various anaerobic bacterial species that were isolated from DD lesions of affected animals. One vaccine also contained Treponema sp. antigen (20% of bacteria count). The vaccine solution without antigens served as placebo and was used in the control group. No significant differences were found between the three groups concerning the prevalence of DD and a DD score at various times. On the basis of the results of this study and those of other studies, the use of herd-specific vaccines against DD cannot be recommended so far.
