MEAT AND BONE MEAL

Rendering is a process that converts waste animal tissue into stable, value-added materials. The carcasses of animals can be used as meat meals after drying or grinding. The product must be substantially free of hooves, horns, bristle, hair and feathers, skin and contents of stomach and viscera. Its protein content ranges from 60-70% useful as lysine supplement but less amount of amino acids like methionine and tryptophan affect their protein quality. It has fat level upto 9%. The enteric factor from the intestinal tract of swine, the ‘ Ackerman’ factor and growth factor in ash are important in meat meal. Meat meal is more valuable for simple-stomached animals than ruminants. Meat meal as well as meat and bone meal are readily eaten by pig and poultry and can be included upto 15% in the diet. Meat and bone meal has been banned in the feeding of ruminants due to the possibility of BSE
