Nutritive value of the protein of antarctic krill (Euphausia sperba) was estimated by rat assay. Results were as follows:1) Weight gain, protein efficiency ratio (PER) and net protein ratio (NPR) for the protein of precooked krill, which was freeze-dried and defatted, were almost the same to those for casein, but these values were obviously lower than those of whole-egg protein.2) The slope ratio technique indicated that the relative nutritive values (RNV) of protein of precooked krill and casein were 87.4 and 77.6% of the value of whole-egg protein, respectively.3) Biological values (BV) of protein at 10% dietary level were 82.2 for precooked krill, 77.6 for raw krill, 84.9 for the extracted protein with alkaline solution, and 87.4 for eviscerated precooked krill. The true digestibility of protein of raw krill was lower than that of precooked krill (raw 88.8%, precooked 91.7%).
