PROBLEM TO BE SOLVED: To considerably reduce probability of misclassification of health condition to enable correctly controlling health condition of dairy cow and enable sooner and more accurately understanding conditions, diseases and the like of dairy cow.SOLUTION: Feed amount detecting sensor part 3 which can detect the amount of feed B at the crib position Xf in stall Ac, and cow body detecting sensor part 4 which detects existence or non-existence of cow body Cm at the predefined positions Px and Py in stall Ac are attached to automatic feeder 2. When the automatic feeder 2 moves to each stall Ac at a prescribed feeding time, the feed amount detecting sensor part 3 detects a residue amount Qr of feed B which is dispensed at the previous feeding time, and thereafter, feed B is dispensed to crib position Xf, at the same time the cow body detecting sensor part 4 detects existence or non-existence of cow body Cm at the predefined positions Px and Py, and based on the detection result of the existence or non-existence and the detection results of residue Qr the health condition of dairy cow C is controlled.COPYRIGHT: (C)2013,JPO&INPIT【課題】 健康状態に対する誤判別の確率を大幅に低減し、乳牛の健康状態を的確に管理可能にするとともに、乳牛の健康や疾病等をより早くより的確に把握可能にする。【解決手段】 自動給餌機2に、ストールAc…の飼槽位置Xf…における飼料B…の量を検出可能な餌量検出センサ部3及びストールAc…の特定位置Px…,Py…における牛体Cm…の有無を検出する牛体検出センサ部4を付設し、所定の給餌時に自動給餌機2が各ストールAc…へ移動した際に、餌量検出センサ部3により、前回の給餌時に投与した飼料B…の残量Qr…を検出し、この後、飼槽位置Xf…に飼料B…の投与を行うとともに、牛体検出センサ部4により、特定位置Px…,Py…における牛体Cm…の存在有無を検出し、当該存在有無の検出結果と残量Qr…の検出結果に基づいて、乳牛C…の健康状態を管理する。【選択図】 図1
