肉骨粉（Meat and Bone Meal）是炼制工业的一种产品，一般为50%的蛋白质，35%的灰以及一些脂肪水分，一般作为动物饲料来使用，如猫粮、狗干粮。

肉骨粉是用不适于食用的家畜躯体、骨、内脏等物作原料，经熬油后的干燥产品。除正常制造过程中无法避免之少量杂质混入外，不得混杂有毛、角、蹄、皮及粪便等物。产品的胃蛋白酶不溶物应在14%以下。

肉骨粉营养成分因原料、加工方法、掺杂物及贮存期间的变化等而有较大差别。原料中骨及结缔组织量大则蛋白质含量低，且利用率低，而含有较多血、蹄角及毛发等物的原料生产出的肉骨粉，虽蛋白质含量高，但利用率低。一般肉骨粉粗蛋白质含量在50％-60％，赖氨酸含量高，蛋氨酸、色氨酸含量低。氨基酸利用率变化大，易因加热过度而不易被动物吸收。含有较多的B族维生素，维生素A、 D较少。钙、磷含量高，磷为可利用磷。尤其原料中含骨骼多时，磷的含量亦多。

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% moisture. It is primarily used in the formulation of animal feed to improve the amino acid profile of the feed. Feeding of MBM to cattle is thought to have been responsible for the spread of BSE (mad cow disease). In most parts of the world, MBM is no longer allowed in feed for ruminant animals. However, MBM is still used to feed monogastric animals. It is widely used in the United States as a low-cost meat in dog food and cat food.
