The effects of inulin supplementation in the diet of laying hens on the antioxidant capacity of refrigerated (0, 2, 4, 6 and 8 weeks) eggs were evaluated. Three hundred commercial laying hens were divided into five treatment groups and fed diets with supplements of 0 (control), 5, 10, 15 or 20 g/kg inulin. The experimental results showed that the use of inulin (15 or 20 g/kg) in the diet for laying hens increased the DPPH and ABTS radical-scavenging activities, total phenolic content and ferric reducing power in the yolks of fresh (stored 0 weeks) and stored eggs (P < 0.05). The antioxidant enzyme (SOD and GSH-Px) activities of the stored egg increased linearly (P < 0.05), and the malonaldehyde (MDA) levels of stored eggs decreased linearly (P < 0.01) as the inulin levels improved at every two weeks of storage. In conclusion, inulin supplementation in the diet of laying hens had the potential to prolong the shelf-life of eggs.
研究了在产蛋鸡日粮中添加菊糖对冷藏（0、2、4、6 和 8 周）鸡蛋抗氧化能力的影响。将 300 只商品产蛋鸡分为 5 个处理组，分别饲喂添加 0（对照）、5、10、15 或 20 g/kg 菊糖的日粮。实验结果表明，在产蛋鸡日粮中使用 15 或 20 g/kg 菊糖可提高新鲜（储存 0 周）和储存鸡蛋（储存 2、4、6 和 8 周）蛋黄中的 DPPH 和 ABTS 自由基清除活性、总酚含量和铁还原能力（P < 0.05）。随着储存时间的延长，储存鸡蛋的抗氧化酶（SOD 和 GSH-Px）活性呈线性增加（P < 0.05），丙二醛（MDA）水平呈线性下降（P < 0.01）。综上所述，在产蛋鸡日粮中添加菊糖具有延长鸡蛋货架期的潜力。
