Although meat and bone meal is used as a type of protein feed material, it can be used with cereal feed to supplement protein deficiency. However, since the meat and bone meal is mainly composed of meat, bone, tendon, ligament, viscera, etc., and also includes waste such as hair, hoof, horn, skin, and blood, the quality varies greatly. If products are made from corrupt raw materials, the quality is even worse, which can even lead to poisoning. The palatability and digestibility of products that have been overheated during processing are reduced. When stored improperly, the fat contained is susceptible to oxidative rancidity, which affects palatability and the quality of animal products. The overall feeding effect is not better than fish meal.
The raw materials of MBM are easily infected with Salmonella. Strict disinfection is required during the processing of livestock and poultry by-products. Meat meal made from the byproducts of diseased livestock should not be fed to similar animals as much as possible. In western countries, many countries have banned the use of meat meal made from ruminant by-products to feed ruminants due to mad cow disease.
Meat and bone meal is a good source of protein, calcium, phosphorus, and vitamin B12 for chickens, but the feed value is far lower than fish meal and soybean meal, and the quality is poor. The dosage is less than 6%, and the supplement is not sufficient. Amino acid.
Meat and bone meal can partially replace fish meal in the pig's compound feed, and more feed will reduce palatability and adversely affect growth. Therefore, the dosage is generally less than 5%. Mostly used in fattening pigs and breeding pigs feed, piglets should be avoided.
Meat and bone meal generally has no adverse effects on cow milk production and milk flavor. The feeding effect on beef cattle is worse than that of pigs and chickens. It can be used with flaxseed meal, soybean meal and cereals with good palatability. The palatability of sheep is not good and it takes a period of adaptation. Because the price of meat meal and meat and bone meal is higher than that of general plant protein feed, and the palatability is poor, it is rarely used in ruminant feed.
