First criterion was determined by region where sires ancester had come. The reason this criterion was taken is from the characteristic formation of the breed, where each sub-population of five original prefectures has its own genetic background. Second criterion was determined by sires' birth year as usual. The mixed models with A^<-1> generally had less PEV (Prediction Error Variance), and the models with regional genetic group and without genetic group had least PEV values. Comparing these two models, bias due to excluding regional genetic group was large, so the model with both the regional genetic group was large, so the model with both the regional genetic group and A^<-1> was concluded to be the best model for sire evaluation using performance test of Japanese Black Cattle.","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/20.500.12000/3969"}]},"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.
