Meat-and-Bone Meal

a protein feed of animal origin, made at meat-packing plants and waste-processing plants from the carcasses of slaughtered animals that are unsuitable for human food and from other dead animals, as well as from slaughterhouse waste and waste products from bacon and canning plants. Meat-and-bone meal is also made by hunting fleets from the carcasses of sea animals.

The raw material for the meal is processed by steam under pressure or cooked in open vats, then dried and ground. Meat-and-bone meal is gray-brown and has a distinctive odor. Its composition and nutritional value vary, depending on the raw material. First-grade meal contains not more than 9 percent moisture, not more than 11 percent fat, not more than 28 percent ash, and at least 50 percent protein. In 1 kg of meat-and-bone meal there is about 0.8 of a standard feed unit and about 320 g of digestible protein. Meat-and-bone meal is used primarily in rations for pigs, poultry, and young farm animals of all types, as well as in many mixed feeds
