Percentage of dressing, eviscerated carcass decreased significantly as dietaryω6/ω3 was reduced; percentage of abdominal fat, subcutaneous fat and intermuscular fat were higher in birds fed lower ratio diets. Drip loss in both breast and thigh muscle increased significantly in birds fedω6/ω3 ratio from 18 to 2.6. Except b* value in breast muscle decreased as birds fed dietary ratio from 5 to 2.6, the tendency for breast and thigh muscle were almost similar; a* values progressively increased as the diets contained increasingω3 content, changes in b* were also significant but the pattern was almost the reverse for changes in a*. Decreasing the dietaryω6/ω3 clearly increased the contents of ALA, EPA and DPA, but not for DHA.

结果表明：①饲喂10：1的日粮显著增加6周龄AA鸡的体重和日采食量；②随着日粮ω6/ω3比值的降低，屠宰率和净膛率显著下降；低ω6/ω3比值的日粮增加腹脂率、皮下脂肪和肌间脂肪；③日粮ω6/ω3比值从18下降到2.6时，胸、腿肌滴水损失显著下降；除日粮比值从5降到2.6时胸肌b*值下降外，胸、腿肌变化规律相似，a*值和b*值变化趋势相反：a*值下降，b*值上升；④日粮ω6/ω3的降低，ω3 PUFA中ALA、EPA和DPA显著增加；⑤肝脏中ALA含量低于胸肌，而其长链衍生物C20：3、EPA和DHA的含量则是肝脏中含量较高。
