Heat damaged fish meal was used to demonstrate the ability of a published bioassay method to discern availability differences resulting from heat treatment. The importance of standardising the test diets was shown and available lysine content of fish meal and oilcake meal samples are tabulated. The bioassay values were compared to a chemical test for availability of lysine and to Nett protein utilisation values for the fish meal.
