Laying hens were fed a high polyunsaturated fatty acid (PUFA) diet with three levels [low (LPO, 0%), medium (MPO, 1.5%), and high (HPO, 3.5%)] of palm oil (PO) or a PUFA diet with tocopherol mix (control). Flax and fish oils were used as PUFA sources in all of the diets. Inclusion of tocopherols resulted in a lower (P < 0.05) thiobarbituric acid reactive substances (TBARS) in the control eggs in white and dark meats. Among the PO treatments, eggs from HPO diet had the lowest TBARS (P < 0.05). A higher (P < 0.05) TBARS was observed for eggs, meat, and liver from hens on the LPO diet. No difference was observed between the TBARS of LPO and MPO dark meat. The C22:6 n-3 fatty acid was lower (P < 0.05) in MPO and HPO eggs and the HPO white meat.
给蛋鸡饲喂含三种水平[低（LPO，0%）、中（MPO，1.5%）和高（HPO，3.5%）]棕榈油（PO）的高多不饱和脂肪酸（PUFA）日粮或含生育酚混合物的PUFA日粮（对照）。在所有日粮中，亚麻油和鱼油用作PUFA来源。添加生育酚使得对照鸡蛋的白肉和深色肉中硫代巴比妥酸反应性物质（TBARS）含量较低（P<0.05）。在PO处理组中，HPO日粮组鸡蛋的TBARS最低（P<0.05）。LPO日粮组母鸡所产鸡蛋、肉和肝脏的TBARS较高（P<0.05）。LPO和MPO深色肉的TBARS之间未观察到差异。MPO和HPO鸡蛋以及HPO白肉中的C22:6 n-3脂肪酸含量较低（P<0.05）。
