This study assessed differences in antioxidant (carotenoid, retinol, retinol-ester, vitamin E and coenzyme Q(10)) 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(10) 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, retinal-esters and total vitamin A were significantly higher in most tissues of wild chukar when compared to farmed chicks (p < 0.05). Coenzyme Qio 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).
