Ingestion of soil during grazing of pastures and forage crops is a common and unavoidable event. Soil contamination of silage and baleage is another challenge that we sometimes need to deal with. Our latest episode explores the whole topic of soil ending up where it doesn’t belong. How much mud and dirt do animals eat during grazing? What factors increase risk of animals eating too much soil? Are there any health or nutrition issues we need to think about when animals eat too much mud and dirt? What happens when we get soil contamination of silage? All this and more. We hope you enjoy our latest podcast.
