The diagnoses used with individual treatments in all in – all out LSO 2000 finishing units. The percentage of batches affected represents the batches where at least one diagnosis in question was recorded in the log book (altogether 572 batches, mass-medicated batches excluded). The percentage of pigs treated describes the median percentage (minimum – maximum) of pigs having different diagnoses in the affected batches.
