I’m a retired vet and have done countless over the years. Knocking out is not necessary and can easily be done in a half decent crush especially back feet. As for dressings, change 2 or 3 times and can normally be done by the farmer after first vet change if competent. Some vets appear to like then fully granulated before stopping the dressing but in my experience it makes no difference.
