Meat and Bone Meal (MBM) is a product of the animal carcass rendering process. Animal carcass trimmings, condemned livers, inedible offal (lungs) and bones are rendered to destroy harmful organisms and made MBM. Meat and Bone Meal is an excellent source of supplemental protein and has a well- balanced amino acid profile. Digestibility of the protein fraction is normally quite high, ranging from 81 to 87%. It is well suited for use in feeding monogastric and provides not only a well- balanced protein source, but also a highly available source of calcium and phosphorus. In addition to the protein (amino acids) meat and bone meal is an excellent source of calcium and phosphorus and some other minerals (K, Mg, Na, etc.). When using meat and bone meal as the primary supplemental protein source the mineral levels may limit its use in some diet formulations. Meat and bone meal like with other animal products is a good source of Vitamin B-12.
