The nutritive value was measured by the chemical composition, neutral detergent fiber (NDF), constituents of NDF and in vitro dry matter disappearance (IVDMD). The cutting heights were 10,25 and 40cm from the ground. The results obtained were summarized as follows : 1. The contents of crude protein, crude fat, nitrogen free extract, crude fiber and crude ash were not significantly affected by the cutting height. 2. The contents of NDF and constituents of NDF were not also significantly affected by the cutting height. 3. At the cutting height of 10,25 and 40cm, the average values of IVDMD were 59.0,60.0 and 60.0%, respectively. 4. At the cutting height of 10,25 and 40cm, the amount of DDMY was 2.40,2.41 and 2.41 tons/10a/year, respectively. From the results, it seemed that the nutritive value of napier grass was not significantly affected by the cutting height.","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":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3881"}]},"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.
