Is your DD control advice still built around slurry management?
Evidence now suggests DD-associated treponemes (T. medium/vicentii-like, T. phagedenis, T. pedis) survive only around 3 days in slurry but are more oxygen-tolerant than once assumed. Direct transmission via contaminated footprints in high cow-traffic areas, along with foot trimming equipment, is now considered the main route, which changes where herd health plans should put their effort.
The updated Digital dermatitis article on Vetlexicon Bovis covers current transmission thinking, M-score grading and integrated control from calves through to dry cows.
