The mimosine degradation product 3-hydroxy-4(1H)-pyridone (DHP) is also reported to be goitrogenic in animals. Inactivation or reduction of mimosine and DHP in the plant before or during the preparation of the plant as feed would enhance the use of the legume as a source of protein for livestock feed. Although purified mimosine is not soluble in distilled water, it become very soluble in the ionic solutions. When the leaves of leucaena were leached in 0\u0026acd;100% sea water or in various concentrations of acids and bases for 24 hrs at 25℃, about 60\u0026acd;95% of the mimosine was extracted. As the rate of mimosine extraction from the leaf of leucaena depended on the concentration of reagents, it was found that 0.05N CH_3COONa was the most effective at extracting 95% of the mimosine. There were no loss of the nutrients, important for use as a livestock feed, such as crude fat, crude fiber and crude protein. The method is relatively simple and removes simultaneously both mimosine and DHP, therefore, it is beleaved to be a method practically applicable for both the small scale treatment of a local farmer and the large scale treatment of a commercial enterprise.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学農学部"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3922"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
