Pomegranate contains bioactive compounds in all its parts. In this study, two levels of pomegranate peel byproduct (PPB) with or without the inclusion of xylanase enzyme were used to supplement laying hens' diet, in a 2 × 2 full factorial design. A total of 48 Isa brown laying hens were fed the following experimental diets for 8 weeks: T1 (2.5% PPB); T2 (2.5% PPB and xylanase); T3 (5% PPB); T4 (5% PPB and xylanase). Eggs collected were analyzed for egg quality parameters. Moreover, egg yolks were analyzed for Malondialdehyde content (MDA), fatty acid profile and total phenolic content. The T2 eggs showed enhanced yolk coloration and greater yolk total phenolic content. The T3 and T4 egg yolks showed lower MDA levels compared with T1, T2. Overall, results have shown that (a) xylanase inclusion affected egg yolk coloration and total phenolic content when combined with 2.5% PPB dietary supplementation; (b) dietary supplementation of 5% PPB resulted in eggs with reduced MDA levels.
石榴的各个部分都含有生物活性化合物。在本研究中，采用2×2全因子设计，使用两种水平的石榴皮副产品（PPB），添加或不添加木聚糖酶，来补充蛋鸡日粮。总共48只伊莎褐蛋鸡被喂食以下实验日粮8周：T1（2.5%PPB）；T2（2.5%PPB和木聚糖酶）；T3（5%PPB）；T4（5%PPB和木聚糖酶）。对收集的鸡蛋进行蛋品质参数分析。此外，对蛋黄进行丙二醛含量（MDA）、脂肪酸谱和总酚含量分析。T2组鸡蛋的蛋黄颜色加深，蛋黄总酚含量更高。与T1、T2组相比，T3和T4组蛋黄的MDA水平更低。总体而言，结果表明：（a）当与2.5%PPB日粮补充剂联合使用时，添加木聚糖酶会影响蛋黄颜色和总酚含量；（b）日粮补充5%PPB可使鸡蛋的MDA水平降低。
