Organ farms were an Tlulaxa innovation to produce replacement organs for the casualties before and during the Butlerian Jihad. Cloned organs and tissues could be grown and cultivated in artificial farms, and then sold commercially all around the League of Nobles. Xavier Harkonnen after the Battle of Zimia received a set of replacement lungs from the Tlulaxa farms. Although he lived, Xavier's sense of smell and taste suffered from the damage inflicted.
