This study was conducted to investigate the effect of dietary maternal Se supplementation on performance of Japanese quail breeders and some physiological traits of their progeny. A total of 240 Japanese quail breeders were used in this study, they divided into two ages, young (16 wk old) and old ages (40 wk old). Each age was distributed into 4 groups, 30 birds in each group, each one included two replicates of 15 birds (11 females and 4 males). All groups were fed the same diet supplemented with 0.0, 0.3, 0.5 or 1 mg selenium yeast (Sel-Plex)/kg feed. The experiment lasted 8 weeks. After hatching, all chicks were fed ad libitum on the basal diet during the whole period. Results indicated that the fertility and hatchability percentages were significantly increased by increasing dietary Se level, fertility and hatchability decreased for breeder hens when the age of birds increased. Se concentration in the egg yolk increased by increasing the dietary Se levels, but deposition of Se in egg yolk decreased in old hens. Concerning the progeny, the results showed that as Se level in maternal diets increased body weight gain (BWG) of their progeny increased, by the way BWG of chicks from young birds were higher than those from old age. Significant improvement in feed conversion for progeny was noted by adding Se in maternal diets especially young birds. Increasing Se in maternal diet significantly also increase triiodothyronine (T3), insulin-like Growth factor-1 (IGF-1) and Glutathione peroxidase (GPx) levels in young hens progeny. Plasma thyroxin (T4) levels were higher in chicks produced from control group compared to those of Se-treatment group. The ratios between plasma T4:T3 showed that Se-treatment facilitated the conversion of T4 to T3. It could be concluded that Japanese quail breeders, young age birds were more efficiently for using dietary selenium. Moreover, the maternal Se-supplementation improved performance and antioxidant status of their progeny for several days after hatching.
