Assuming that agglutination above plus one by the modified method of CMT is defined as a positive, the Southern district showed 29.7% and the Northern district 28.3% classified by the quarter; the corresponding figures in terms of the number of cattle was 61.2% and 63.5%, respectively. Thus there was seen no great difference between the two districts. The positive rate in the summer and autumn seasons in the Southern district was almost the same for both the quarter and the number of cattle. However, the positive rate in the Northern district varied greatly with the area. A area had 33.8% by quarter and 72.8% by the number of cattle, whereas B area had 16.0% and 42.2%, respectively. Dairy cattle that were positive were mostly positive in one or two quarters, occupying 78.9%-82.9%. Dairy cattle showing positive in all of the quarters were very few. The relationship between agglutination degree by the modified CMT and the number of cells according to the Breed method was as follows : The greater the degree of the agglutination, the greater the number of cells, and the average number of cells with plus one agglutination exceeded 500,000/ml of cell number. However, with this plus one agglutination, the majoirity of the samples had below 490,000/ml of cell number.","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/20.500.12000/4039"}]},"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.
