RENDERED PRODUCTS IN SWINE NUTRITION

Summary Numerous rendered products can be used in swine diets. In general, these by-products of the packing/rendering industry are good sources of amino acids, calcium, phosphorus, and other minerals, as well as B-complex vitamins. The major animal-derived by-products used in swine diets are meat meal, meat and bone meal, fish meal, dried blood products (blood meal, spray-dried plasma, and spraydried blood cells), steamed bone meal, and rendered animal fats (tallow, grease, and mixtures of animal fats). Small amounts of poultry by-product meal and hydrolyzed feather meal are also use, but to a lesser extent. This chapter gives an overview of the composition of these products and their nutritional value for swine.
