A lot of linolenic acids are included in the perilla seed, and rice and barley in sub-standard size are hoped to use for feedstuffs produced in local area. Therefore, we have supplied laying hens with perilla seeds and sub-standard size rice and barley a long term, and examined production of functional eggs. We analyzed fatty acid composition in feedstuffs. Linoleic acids content in sub-standard size rice (45.1%) was lower than that of corn (58.1%). On the other, linolenic acids content in sub-standard size barley was 5.0%, and that of perilla seed was 64.0%. A n-6/n-3 ratio in egg yolk of the sub-standard size rice group or barley group was about 3, and that of the perilla seeds addition group was below 2, however that of the conventional group was about 5. The supplied feedstuffs affected the yolk color, but not affected egg laying or quality. A cost of feed to produce 1 kg egg was higher at the sub-standard size rice group, but lower at the sub-standard size barley.
