PROBLEM TO BE SOLVED: To provide drinking water for livestock, a method for producing the drinking water for the livestock and a method for rearing the livestock, capable of improving rearing productivity accompanying with the improvement of health of the livestock such as the improvement of health state of the livestock, the reduction of rearing cost, the improvement of quality of reared products, etc.SOLUTION: Drinking water for livestock uses electrolytic hypochlorite water as an active ingredient. The effective chlorine concentration is 10 to 500 ppm, and a hydrogen ion exponent is pH7.5 to 9.0. The drinking water for the livestock uses the electrolytic hypochlorite water obtained by the electrolysis of an aqueous sodium chloride solution with a non-diaphragm type electrolysis chamber, as an active ingredient of the drinking water for the livestock. A water-drinking program in that after making the livestock drink the drinking water for the livestock for a prescribed period of time, water is given to the livestock for a half period of the prescribed period, is repeatedly performed for the livestock.COPYRIGHT: (C)2014,JPO&INPIT【課題】家畜の健康状態の改善、飼育費用の削減、飼育生産物の品質向上など、家畜の健康改善に伴う飼育生産性を向上させることができる家畜用飲料水、家畜用飲料水の製造方法及び家畜の飼育方法を提供する。【解決手段】本発明の家畜用飲料水は、電解次亜水を有効成分とすることを特徴とする。有効塩素濃度は、10~500ppmであり、水素イオン指数は、pH7.5~9.0である。また、本発明の家畜用飲料水は、塩化ナトリウム水溶液を無隔膜電解槽で電気分解することによって得られた電解次亜水を家畜用飲料水の有効成分とする。この家畜用飲料水を家畜に所定期間だけ飲用させた後に所定期間の半分だけ前記家畜に水を飲用させる水分飲用プログラムを家畜に繰り返し実施する。【選択図】なし
