DRINKING WATER STATE SPECIFICATION DEVICE, DRINKING WATER STATE SPECIFICATION PROGRAM AND STORAGE MEDIUM

To provide a drinking water state specification device for suppressing erroneous detection of a drinking water action more than conventional practice.SOLUTION: In a monitoring system 100 relating to this disclosure, a terminal 20 in a stomach is indwelled in the stomach 10S of a plurality of cows 10, and information of temperature F in the stomach is transmitted to a monitoring terminal 50 by radio. In the disclosure, the monitoring terminal 50 specifies a drinking water state on the basis of a change in the temperature F in the stomach by using the change in the temperature F in the stomach when a cow 10 performs a driving water action to allow water to go into the stomach 10S. According to this configuration, it is possible to specify that a drinking water action is performed when the water actually goes into the stomach 10S. This can suppress the occurrence of a problem of making an erroneous determination that a drinking water action is performed even though the drinking water action actually is not performed in comparison with a conventional configuration for specifying the drinking water action due to movement of the cow 10.SELECTED DRAWING: Figure 4 【課題】従来よりも動物の飲水行動の誤検知を抑制する飲水状況特定装置を提供する。【解決手段】本開示監視システム１００では、複数の牛１０の胃袋１０Ｓ内に胃袋内端末２０が留置されて胃袋内温度Ｆの情報が監視端末５０に無線送信される。本開示では、牛１０が飲水行動を行って胃袋１０Ｓ内に水が入ったときに胃袋内温度Ｆが変化することを利用し、監視端末５０は、胃袋内温度Ｆの変化に基づいて飲水状況を特定する。この構成によれば、実際に胃袋１０Ｓ内に水が入ったときに飲水行動を行ったことを特定できる。これにより、牛１０の動きによって飲水行動を特定する従来の構成と比較して、実際には飲水行動を行っていないのに飲水行動を行っていると誤判断するという問題の発生を抑えることができる。【選択図】図４
