Meat and bone meal (MBM) is a product of the rendering industry. It is typically about 48–52% protein, 33–35% ash, 8–12% fat, and 4–7% water. It is primarily used in the formulation of animal feed to improve the amino acid profile of the feed. … However, it is still used to feed monogastric animals.
Meat and bone meal is not considered detrimental to intestinal flora, stool consistency or stool volume when included in dog or cat diets. Beef is often blamed for food hypersensitivities, so MBM is often one of the first ingredients removed in an “elimination” diet regimen.
