Rapeseed meal (RSM) is the richest source of commercially available home grown protein in the UK, but its inclusion in livestock diets is approximately half that of soyabean meal (SBM, DEFRA, 2004). RSM has a lower protein and available lysine content than SBM but increased nutrient digestibility was observed when pigs were fed RSM supplemented with non-starch polysaccharide degrading enzymes (Hoare et al., 2003). The objective of this experiment was to determine the effect of adding different amounts of a cell wall degrading enzyme on the available amino acid content of RSM as estimated in poultry.
