JBL meant well: the purely plant-based tortoise food JBL Herbil received the coveted Bioland seal because it is made exclusively using Bioland grasses. The owner liked it more than their tortoises, who found the food a bit bland.
Following Bioland guidelines, neither healthy minerals nor tasty herbs could be added to the food. This has now changed: no longer following the regulating Bioland seal, the new JBL Herbil contains vegetable and herbs (95%) with essential minerals (a result of the JBL research project cooperation with Munich University) which has led to increased palatability for the tortoises. In the acceptance test the new JBL Herbil was preferred not only to the previous Herbil but also to ALL tested competitors.
