PROBLEM TO BE SOLVED: To provide raising methods of livestock in which the activity of the water used for raising livestock is efficiently enhanced, and to provide a water processor for raising livestock.SOLUTION: When raising livestock, a processed water is used, in which an activity is enhanced by applying a complex sound wave with a frequency band generated by a jet type first ultrasonic wave generator 210 ranging from an audible range to an ultrasonic range, and an ultrasonic wave generated by an electrical type second ultrasonic generator 220. Since the second ultrasonic generator 220 generates a single frequency ultrasonic wave, the processed water is applied with a complex sound wave and a single frequency ultrasonic wave of 10 kHz, 15 kHz, 28 kHz, and the like.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】家畜の飼育に用いる水の活性度を効率よく高めた家畜の飼育方法、および家畜飼育用の水処理装置を提供すること。【解決手段】家畜を飼育するにあたっては、噴流式の第1超音波発生器210により発生させた周波数帯域が可聴域から超音波域の複合音波と、電気式の第2超音波発生器220により発生させた超音波とを印加して活性度を高めた処理水を用いる。第2超音波発生器220は、単一周波数の超音波を発生させるため、処理水は、複合音波と、10kHz、15kHz、28kHz・・の単一周波数の超音波とが印加されることになる。【選択図】図5
