KNZ® KNZ® supplies high quality salt and other minerals intended for animals. KNZ® stands for “Koninklijke Nederlandse Zoutindustrie,” which means “Royal Dutch Salt.” The company was established in the Netherlands in 1918. The KNZ® brand is known all around the world. KNZ supplies “free choice” salt for livestock. Salt is essential in life and supplies two essential elements to the feed, sodium and chloride. In their behaviors, animals demonstrate a “nutritional wisdom” for salt, so free choice means the animals are able to decide for themselves how much additional salt they take in depending on constantly changing daily needs. We press salt into blocks so that the animals can ingest the salt they want by licking. Trace minerals and vitamins are added to support animal health.* For more information please visit our website or contact us. *Certain statements may not be applicable in specific geographical regions.
