These physiological responses were measured by blood composition, rumen juice protozoa and some other means under the following conditions : 29℃・86% in the barn, 20℃・85% at one environment in the climate chamber and 30℃・85% at another environment in the climate chamber. The cattle were compared under the three environments of this experiment. Rectal temperature, heart rate and respiratory rate significantly decreased from respectively 38.60±0.16℃, 70.4±2.1 beats/min and 19.4±4.2 breaths/min in the barn to 38.19±0.12℃, 59.2±3.2 beats/min and 19.4±2.8 breaths/min at 20℃・85% in the climate chamber (P<0.01), and 38.88±0.20℃, 79.0±1.9 beats/min and 64.2±6.1 breaths/min at 30℃・85% in a chamber were significantly higher than those at 20℃・85% in a chamber. There was no significantly change in the values of erythrocyte, leucocyte, hematocrit and hemoglobin or in erythrocyte sedimentation rate, plasma glucose, plasma free fatty acid, plasma albumin, plasma cholesterol, plasma thyroxine, plasma protein, urine ph, rumem juice ph and feed intake in each of three environments. However, ophryosolecidae, isotrichidae and total protozoa in rumen were significantly higher at the time 21 : 00 than at 9 : 00 in each of these three environments (P<0.01). The results mentioned above suggest that animals adapt themselves to high temperatures and high relative humidity in a subtropical zone. Japanese Black cattle fed in a barn in Okinawan subtropical zone generally maintain their homeostasis and productions (growth, reproduction, and etc.) by using physiological elements that regulate body temperature.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学農学部","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3973"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0370-4246","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00250548","subitem_source_identifier_type":"NCID"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学農学部学術報告","subitem_source_title_language":"ja"},{"subitem_source_title":"The Science Bulletin of the Faculty of Agriculture.
