Animal products are products of rendering industry and are generally classified as either animal protein or fats. Animal proteins not only supply protein and amino acids, but they can also be a good source of energy and minerals.Meat & Bone Meal (MBM)
MBM is a product of rendering industry. Rendering (cooking) process produces a nutritional and economical feed ingredient. Meat and bone meal is an excellent source of protein. High quality meal is usually guaranteed to contain a minimum of 50% protein content. Typically, if the phosphorus content is above 4.5 % P, it is called as Meat and Bone Meal but if it is below that level, it is referred to as Meat Meal only. MBM is primarily used in animal feed formulation to improve the amino acid profile of the feed. It is used to feed monogastric animals, used as ingredient in petfood. In poultry diets, meat and bone meal is typically limited to less than 5% of the diet content because of the high calcium, phosphorus, and lysine content of the meal.Poultry By-Product Meal (PBM)
Poultry protein meal (hydrolyzed poultry feathers), meat and bone meals, blood meals, and poultry by-product meal. Are produced by the rendering industry. The raw materials of this industry consist largely of by-products from the meat packing and processing industries and trimmings from retail stores, restaurants, and other establishments handling meats. The rendering operations perform a very important function by recycling inedible tissues of poultry and other ingredients for livestock, poultry and pets. The proteins and minerals in the animal by-product help fill the need for essential nutrients available for use in feeds.
In several nutrition experiments conducted time and again, animal protein invariably proved to be superior to vegetable protein in promoting growth in production of animals. This superiority was considered to be inherent in the protein itself and as such animal proteins were considered indispensable for the animal feed formulation. Animal protein have justifiably become an important part of the feed ingredient mix.
