This chapter presents information on the different classes of animal discards that are available as well as factors that could influence their use in the diets of livestock. Meat and bone meal (MBM) is one of the most important animal discards that are important in swine and poultry feed both in terms of availability, cost, and nutrient and energy composition. MBM tankage, as well as meat meal and meat meal tankage are used to describe different types of animal discards that are composed primarily of meat and bone or meat alone. Miller and De Boer and Reese et al. provided information on the recommended level of inclusion of some animal discards in livestock feeds. The main challenge of using animal discards in livestock feed is that the nutrient and energy contents of these products vary widely between and within discards depending on the source, processing techniques, and geographical location.
