The goats weighing less than twenty-five kilograms were classified as miniature goats. Five morpho-genetic characters and body measurements of thirteen different parts were recorded in 733 adult female goats which were over one year old and had delivered previously. This research was conducted on the goats which had been kept in the islands of Yonaguni, Ishigaki, Miyako, Kume, Zamami, Southern and Central Okinawa, Northern Okinawa, Iheya, Izena and Aguni. The period of investigation was from June 1975 to August 1976. The results are summarized as follows : 1. The average withers heigth, oblique body length, hip width, chest girth and body weight in the Okinawa meat goats were 58,64,14,74cm and 33kg, respectively. The body measurements of goats in Okinawa and Miyako islands were larger than those of goats in other islands, while those of goats in Iheya and Kume islands were smaller. 2. The average body size of white goats was larger than that of colored ones. The relations of body size among animals on other morpho-genetic characters were : wattled>wattleless, bearded>beardless, polled>horned and lacking>having of supernumerary teat. 3. Most of simple correlation coefficients obtained by calcurating every possible pairs of thirteen traits in the pooled data were highly positive. Especially, the correlations (0.897∿0.803) of body weight with chest girth, chest depth and body length were very high. On the other hand, correlations in miniature goats were relatively low and lower than those in the pooled data. 4. For pooled data and miniature goat, the respective frequencies of appearance of animals with white color, wattles, beard, horns and supernumerary teats were 84,73; 28,21; 85,78; 68,78 and 44,52%. 5. It was suggested that the ideal miniature goats as laboratory animals should have white coat color and beard, but have not horns, wattles and supernumerary teats. Breeding objectives for withers hight, oblique body length and body weight of miniature goats should be 42∿48,47∿53cm, and 13∿18kg, respectively. It was also suggested that beard should be excluded from the characteristics for the native type of Okinawa goats.","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/20.500.12000/4210"}]},"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.
