なる。In the present invention, a polyphenol compound and vitamin E are used as substances having an antioxidant action. However, since the former is water-soluble, it is diffused into water when fed as it is, and spread to cultured fish. Inability to feed effectively. Further, since the latter vitamin E is fat-soluble, it cannot be uniformly mixed with the polyphenol compound in its original form. Therefore, the present invention has one major feature in that a water-soluble polyphenol compound and a fat-soluble vitamin E are formulated by further blending an emulsifier and an oil and fat, and the obtained antioxidant bait is An excellent effect of suppressing the diffusion of the components of the composition into water is exhibited. Thereby, the composition for antioxidant feed of the present invention can be more efficiently fed to cultured fish. Furthermore, by formulating the antioxidant feed composition of the present invention, it becomes possible to uniformly disperse the composition in the feed.
