Four fish meals were subjected to a Nett Protein Utilization (NPU) study of which two were then tested in broiler rations. The NPU values revealed significant differences between fish meals but the broiler growth rate failed to indicate differences in protein quality of the fish meals. Values for available lysine (f1uorodinitrobenzene method) are also presented for the four fish meals as amino acid analyses. The relative merit of NPU for determining the protein quality of a fish meal is discussed.
