Thirteen commercially available porcine meat and bone meal products from both independent renderers and commercial packing plants were evaluated in a lamb-digestion study for the following variables: crude protein, undegradable intake protein, metabolizable protein, apparent nitrogen digestibility and true nitrogen digestibility. As a whole, the products varied widely with respect to all of the variables measured with the exception of apparent nitrogen digestibility, indicating that feeding value of commercially available meat and bone meal products also varies widely, although all of the products tested had acceptable protein digestibilities.
