This study assessed differences in antioxidant (carotenoid, retinol, retinol-ester, vitamin E and coenzyme Q) composition of egg yolk and tissue in chukar partridges (Alectoris chukar) newly hatched from eggs of birds maintained in captivity on commercial maize-soybean based diets and birds from the wild whose diet was obtained from the natural environment. All eggs were incubated in a commercial hatchery. Day-old chicks from both groups were sacrificed and dissected for antioxidant analysis. Fat soluble antioxidant concentrations of egg yolk and tissues were determined by HPLC. Total carotenoids, retinol, alpha-tocopherol, and total vitamin E concentration of wild egg yolks were significantly higher compared to yolks from farm-reared birds (p<0.05). However, gamma tocopherol, and coenzyme Q were not significantly different in the yolks of either wild or farmed birds (p>0.05). The concentration of total carotenoids in all tissues of wild chukar one-day old partridges was significantly higher than in farmed one-day old chukar partridge tissues (p<0.05). Alpha tocopherol, free-retinol, retinol-esters and total vitamin A were significantly higher in most tissues of wild chukar when compared to farmed chicks (p<0.05). Coenzyme Q concentrations of heart, kidney and brain tissues of farm-reared chukar day old chicks were significantly higher than tissues from wild birds, although leg and breast tissues of wild chicks were significantly higher than in farmed birds (p<0.05). These findings suggest that maternal access to antioxidants in the diet of farmed chukar partridges could positively influence fat soluble antioxidant concentrations in the egg yolk and tissues of day old chicks.
本研究评估了以商业玉米 - 大豆为基础日粮圈养的鸟类所产蛋孵化出的新孵出石鸡（石鸡）蛋黄和组织中的抗氧化剂（类胡萝卜素、视黄醇、视黄醇酯、维生素E和辅酶Q）成分与来自自然环境野生鸟类所产蛋孵化出的石鸡之间的差异。所有鸡蛋均在商业孵化场孵化。两组一日龄雏鸡均处死后进行解剖以进行抗氧化剂分析。通过高效液相色谱法测定蛋黄和组织中脂溶性抗氧化剂的浓度。与养殖鸟类的蛋黄相比，野生蛋黄中的总类胡萝卜素、视黄醇、α-生育酚和总维生素E浓度显著更高（p<0.05）。然而，野生或养殖鸟类蛋黄中的γ-生育酚和辅酶Q没有显著差异（p>0.05）。野生一日龄石鸡所有组织中的总类胡萝卜素浓度显著高于养殖的一日龄石鸡组织（p<0.05）。与养殖雏鸡相比，野生石鸡的大多数组织中α-生育酚、游离视黄醇、视黄醇酯和总维生素A显著更高（p<0.05）。养殖的一日龄石鸡雏鸡心脏、肾脏和脑组织中的辅酶Q浓度显著高于野生鸟类的组织，尽管野生雏鸡的腿部和胸部组织显著高于养殖鸟类（p<0.05）。这些发现表明，养殖石鸡的母体在日粮中获取抗氧化剂可能会对一日龄雏鸡的蛋黄和组织中的脂溶性抗氧化剂浓度产生积极影响。
