= 1.86x + 122という回帰式が得られた。91頭時を除く乳牛群で、飼養頭数と総訪問回数(回/日)の間に、y=-2.66x+762という直線回帰式が得られた。両関係から141頭時に386回で理論的な自動搾乳機利用の限界に達すると推測した。１頭当たりの訪問回数は、飼養頭数の増加に伴い直線的に減少した。１頭当たりの搾乳回数(y)は飼養頭数(x)との間に、102頭以上の牛群で、y＝-0.020x+5.14という回帰式が得られた。両関係から140頭時に通過回数はゼロとなり、自由往来型における飼養頭数の理論的限界が推定された。自動搾乳システムの円滑な運営には、109頭付近での使用が適切と考えた。","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"","nameIdentifierScheme":"ISNI","nameIdentifierURI":"http://www.isni.org/isni/"}]}],"familyNames":[{"familyName":"森田","familyNameLang":"ja"}],"givenNames":[{"givenName":"茂","givenNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"26","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9317","nameIdentifierScheme":"教員総覧","nameIdentifierURI":"https://www.rakuno.ac.jp/archives/teacher/9317.html"}],"names":[{"name":"森田,
