In this series, we have explained in detail how correct functional trimming can prevent mechanical lameness. The previous article was devoted to the most common form of bacterial lameness in dairy operations, namely digital dermatitis (DD). This can be successfully treated by a professional hoof trimmer, but the emphasis must be on herd prevention.
