To provide a method for breeding livestock capable of increasing the amount of drinking water of livestock.SOLUTION: The livestock breeding method of the present invention comprises a water pipe 13 through which water passes, permanent magnets 14A, 14B having a magnetically acting surface for exerting magnetism on water passing through the inside of the water pipe 13, And the yokes 16A and 16B which are bent in a substantially inverted U shape, the magnetic treatment water magnetically treated by the water activation device 1 is given to the livestock as drinking water. This makes it possible to increase the amount of drinking water of domestic animals.(FIG. 4A).【課題】家畜の飲水量を増加させることが可能な家畜の飼育方法を提供する。【解決手段】本発明の家畜の飼育方法は、内部を水が通過する通水管13と、通水管13の内部を通過する水に磁気を作用させる磁気作用面を有する永久磁石14A,14Bと、略コの字型に折曲されているヨーク16A,16Bと、を備える水活性化装置1により磁気処理された磁気処理水を、家畜に、飲料水として飲ませる。これにより、家畜の飲水量を増加させることが可能となる。【選択図】図4A
