Dried pulp is a plant-based fibre-rich food, sold in the form of 6- and 8-mm pellets, with ISO 9001 and IFIS certification. It is suitable for ruminants because there is less risk of acidosis and can be fed to heifers, weanlings and cull cows. It is also suitable for swine since it regulates the bowel function and promotes better growth for piglets.
Cereal
