社会解決研究プロジェクトによって行われた．琉球大学農学部附属亜熱帯フィールド科学教育研究センター内畜舎においてスマート畜産を実践するための実証試験として，1. 消費電力計測機の設置，2. 畜舎内への簡易Wi-Fi の整備，3. 移動式太陽光発電システムの自作，4. ミニローダの改造を行い，脱炭素社会に対応し得る実用レベルのスマート畜産の課題を検討した．その結果，消費電力の年間のモニタリング調査から，畜舎で24 時間稼働している扇風機と家畜用ヒータの消費電力量は必ずしも高くはなく，畜産経営を圧迫するものではなかった．畜舎での6,000 kWh/年の消費電力量を太陽光発電システムで活用する場合は，現時点での費用対効果は低い．畜舎周辺のDX 化（Wi-Fi 設置）によって畜舎内外の環境データの収集が可能となり，家畜の行動をスマートフォンを用いて観察できたが，研究面では画像や動画などのデータ量の多さによって処理に時間を要する課題が出てきた．畜舎内の環境データの解析から，7 月上旬から10 月上旬（3 ヶ月間）は暑熱対策が，12 月上旬から3 月上旬（3 ヶ月間）は寒冷対策が必要であることが明らかになった．",
