PROBLEM TO BE SOLVED: To provide a method for discriminating the health state of daily cattle, by which the health state of the daily cattle can certainly and quickly be grasped.SOLUTION: This method for discriminating the health state of daily cattle includes setting discrimination conditions for reaction data Di related to the detection timing of a cattle number detection sensor 3i for detecting the cattle number of daily cattle C by preliminarily setting to at least an automatic feeding machine 2 and/or reaction data Dp related to the detection timing of a cattle body detection sensor 3p for detecting the presence of the daily cattle C, detecting reaction data Di related to the detection timing of the cattle number detection sensor 3i and reaction data Dp related to the detection timing of the cattle body detection sensor 3p, when the automatic feeding machine 2 is moved to an optional stall Ac to feed, and then discriminating the health state of the daily cattle C on the basis of the detected reaction data Di, Dp and the discrimination conditions. Thus, the health state of the daily cattle can be discriminated at an excellent cost efficiency without giving a useless stress to the daily cattle.COPYRIGHT: (C)2010,JPO&INPIT【課題】 乳牛の健康状態を的確かつ早期に把握可能にする。乳牛に対して無用なストレスを与えることがないとともに、低コスト性に優れる。【解決手段】 予め、少なくとも、自動給餌機2に設けることにより乳牛C…の牛番を検出する牛番検出センサ3iの検出タイミングに係わる反応データDi…と乳牛C…の存在を検出する牛体検出センサ3pの検出タイミングに係わる反応データDp…の一つ及び/又は組合わせに対する判別条件を設定するとともに、自動給餌機2が任意のストールAcに移動して給餌を行う際に、牛番検出センサ3iの検出タイミングに係わる反応データDi及び牛体検出センサ3pの検出タイミングに係わる反応データDpを検出し、検出した反応データDi,Dpと判別条件に基づいて乳牛Cの健康状態を判別処理する。【選択図】 図1
