Native breeds named in this brand's cross: Kurokashiwa ・ Shamo ・ Rhode Island Red （All 38 native breeds）
The 75% native-breed blood percentage is stated in the “characteristics” section of the specification, measured against the JAS standard for jidori. The “dedicated feed using local rice and rice bran” appears in the section explaining why the characteristics are attributable to the area — it is background, not a production requirement.
