Japanese quail is an increasingly important bird of economic importance for commercial egg and meat production, particularly in developing countries. There a need research aimed at improving efficiency these birds during stressful challenges, such as oxidative stress. Coenzyme Q10 (CoQ10), highly functional antioxidant, protects cells against This study was conducted to determine the effects CoQ10 on reproductive performance under cadmium (Cd) challenge. A total 216 six-wk-old were randomly allocated into 3 groups 8 wk experimental trial. The treatments include negative control (NC): feeding basal diet; positive (PC): diet administration (1 mg/100 g BW, 10 11 age), (CdQ10): supplemented (900 mg/kg diet) Cd administration. At 13 age, body weight, mortality, oviduct, ovarian biometry, recorded. Histology histopathology isthmus magnum, fertility, hatchability, hatchling quality, HSP70 mRNA transcript abundance utero-vaginal junction (UVJ) evaluated. Positive CdQ10 group had no significant effect live stroma follicle size, fertility; however, increased (P < 0.01) mortality rate PC compared NC groups. produced more eggs higher quality 0.01). thickness height magnum folds overall oviduct weight with supplementation Compared PC, reduction infiltration inflammatory cells.
