The genetic parameters estimated were phenotypic and genetic correlations and heritability. The animals used were 4,584 heifers which had been registered in the Okinawa Animal Breeding Association from 1973 to 1977. Overall least-squares means and heritability estimates with standard error for wither height, chest girth, chest width, hip width and thurl width were 119.06±0.27cm; 0.281±0.046,167.82±0.77cm; 0.493±0.053,61.93±0.26cm; 0.449±0.051,43.60±0.24cm; 0.312±0.047 and 41.31±0.19cm; 0.235±0.045,respectively. Age of heifers were adjusted for each cattle to 27.44 months as their age varied from 16 to 36 months. Body measurements were compared among places of birth within Okinawa prefecture. The body size of heifers in Ishigaki, Kume, Miyako and Izena islands was larger than those in Yonaguni, Taketomi and Izena islands. Comparing the body measurements among the birth places of brought heifers, heifers born from Tottori, Kagoshima and Miyazaki prefectures were larger than those from Okayama and Shimane prefectures. The body size of heifers in Miyako, Kume and Ie islands were larger than those raised in Yonaguni, Taketomi, Ishigaki and Izena islands. Yearly means of the body measurements showed a quadratic trend for the body measurements which had bottom in 1975. The body size of heifers born in summer was larger than for heifers born in spring. The interactions between year and season were significant in some combinations. The ranges of phenotypic and genetic correlations among the five body measurements were 0.417 to 0.746 and 0.606 to 0.981,respectivey.","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/20.500.12000/4005"}]},"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.
