The objective of the present study was to investigate the effect of the natural flavonoid quercetin dietary supplementation on the alteration of egg metallome by applying the basic principles of elemental metabolomics. One hundred and ninety-two laying hens were allocated into 4 treatment groups: the control (C) group that was fed with a commercial basal diet and the other experimental groups that were offered the same diet further supplemented with quercetin at 200, 400 and 800 mg per kg of feed (Q2, Q4 and Q8 group, respectively) for 28 days. The diets contained the same vitamin and mineral premix, thus all birds received the same amount of elements since no differences on feed intake existed. The egg elemental profile consisted of As, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Sb, Se, Sr, V, Zn and was determined using inductively coupled plasma mass spectrometry (ICP-MS). Quercetin supplementation altered the elemental profile. Most notably, quercetin altered the element concentrations predominantly in egg shell and albumen. It increased the concentration of Sb while reduced that of Cr and Se in both egg shell and albumen. Moreover, it increased As, Cd in albumen and V in yolk, while compared to the control, reduced As, Cd, Cr, Cu and V and also raised Ca, Fe, Mg and Ni in egg shell. The presence of quercetin led to differentiation of the deposition of certain trace minerals in egg compartments compared to that of hens fed a basal diet, possibly indicating that tailor made eggs for specific nutritional and health requirements could be created in the future.

槲皮素和蛋金属酶

本研究的目的是通过应用元素代谢组学的基本原理,研究天然类黄酮槲皮素膳食补充剂对蛋类金属蛋白酶改变的影响。192只产蛋鸡被分为4个治疗组:对照组(C)组以商业基础饮食喂养,其他实验组以相同的饮食进一步补充200、400和800槲皮素毫克每千克饲料(分别为Q2,Q4和Q8组)持续28天。饮食中含有相同的维生素和矿物质预混物,因此所有家禽都接受相同数量的元素,因为饲料摄入量没有差异。蛋的元素分布由As,Ca,Cd,Co,Cr,Cu,Fe,Mg,Mn,Mo,Ni,Pb,Sb,Se,Sr,V组成 Zn和使用电感耦合等离子体质谱法(ICP-MS)测定。槲皮素补充剂改变了元素谱。最值得注意的是,槲皮素主要改变蛋壳和蛋白中的元素浓度。它在蛋壳和蛋白中都增加了Sb的浓度,同时降低了Cr和Se的浓度。此外,与对照相比,它增加了蛋清中的As,Cd和蛋黄中的V,同时减少了蛋壳中的As,Cd,Cr,Cu和V,还增加了Ca,Fe,Mg和Ni。与饲喂基础饮食的母鸡相比,槲皮素的存在导致蛋室中某些微量矿物质的沉积有所不同,这可能表明将来可能会生产出满足特定营养和健康要求的定制鸡蛋。槲皮素补充剂改变了元素谱。最值得注意的是,槲皮素主要改变蛋壳和蛋白中的元素浓度。它在蛋壳和蛋白中均增加了Sb的浓度,同时降低了Cr和Se的浓度。此外,与对照相比,它增加了蛋清中的As,Cd和蛋黄中的V,同时减少了蛋壳中的As,Cd,Cr,Cu和V,还增加了Ca,Fe,Mg和Ni。与饲喂基础饮食的母鸡相比,槲皮素的存在导致蛋室中某些微量矿物质的沉积有所不同,这可能表明将来可能会生产出满足特定营养和健康要求的定制鸡蛋。槲皮素补充剂改变了元素谱。最值得注意的是,槲皮素主要改变蛋壳和蛋白中的元素浓度。它在蛋壳和蛋白中都增加了Sb的浓度,同时降低了Cr和Se的浓度。此外,与对照相比,它增加了蛋清中的As,Cd和蛋黄中的V,同时减少了蛋壳中的As,Cd,Cr,Cu和V,还增加了Ca,Fe,Mg和Ni。与饲喂基础饮食的母鸡相比,槲皮素的存在导致蛋室中某些微量矿物质的沉积有所不同,这可能表明将来可能会生产出满足特定营养和健康要求的定制鸡蛋。它在蛋壳和蛋白中都增加了Sb的浓度,同时降低了Cr和Se的浓度。此外,与对照相比,它增加了蛋清中的As,Cd和蛋黄中的V,同时减少了蛋壳中的As,Cd,Cr,Cu和V,还增加了Ca,Fe,Mg和Ni。与饲喂基础饮食的母鸡相比,槲皮素的存在导致蛋室中某些微量矿物质的沉积有所不同,这可能表明将来可能会生产出满足特定营养和健康要求的定制鸡蛋。它在蛋壳和蛋白中都增加了Sb的浓度,同时降低了Cr和Se的浓度。此外,与对照相比,它增加了蛋清中的As,Cd和蛋黄中的V,同时减少了蛋壳中的As,Cd,Cr,Cu和V,还增加了Ca,Fe,Mg和Ni。与饲喂基础饮食的母鸡相比,槲皮素的存在导致蛋室中某些微量矿物质的沉积有所不同,这可能表明将来可能会生产出满足特定营养和健康要求的定制鸡蛋。
