Abstract

A good deal of fish viscera or the protein liquid after extracting oil has been abandoned every year.<br> The authors have studied its utilization and succeeded in the production of a fowl feed-S. P. Feed-in an industrial scale.<br> In the present paper described the comparative study of amino acid composition and contents of B-group vitamins in the protein of the fish viscera prepared from cuttle fish, octopus, atka mackerel and pollack. In addition above components in the S. P. Feed made from cuttle fish liver, commercial sardine meal and fish soluble (made in U. S. A.) were compared.<br> The results obtained were tabulated in Table 6, 7 and 8: sixteen amino acids were determined by colorimetric paperchtomatography and B-group vitamine by chemical methods except vitamine B12.<br> Distribution of amino-acids in the viscera proteins seemed to be relatively uniform in the fish muscle proteins, irrespective of the kind of viscera. It is noticeable that methionine content in these viscera preparations is higher than in the fish muscle protein and others, although there seemed to be some difference in the content of several amino acids.<br> While the B-group vitamine contents of fish visceia are generally high, those of Cephalopoda are particularly rich in B2 and B12, and thus the Cephalopoda viscera seemes to be a good material for domestic fowl feed.<br> From the amino acid composition and vitamine contens, the fish soluble feed made from these fish viscera may be superior to sardine meal and so-called fish soluble.
