Abstract :
Used were a total of 810 seven-day-old Japanese quails. The birds received a basal diet with three
levels of two vitamins – vitamin E (ROVIMIX
®
E-50 SD; stable source of
vitamin E in feed, DL-α
Tocopheryl acetate) 60, 120 and 240 mg/kg of diet, vitamin C (ROVIMIX
®
Stay-C 35; stable source
of vitamin C in feed, L ascorbic acid) 60, 120 and 240 mg/kg of diet. Birds were reared at 3

°
C
during the treatment period (week 0 to week 16 of age). At weeks 15-16 eggs were collected from
the pens and put into incubators. The highest mean sexual maturity body weight (SMBW) and
egg weight (EW) values were determined in a combination of 240 mg of Vitamin E and 240 mg of
vitamin C group. The effect of treatment groups on fertility (F) ratio was found to be significant
(P≤0.01). When the fertility ratios are compared both combinations of 240 mg of vitamin E and 240
mg of vitamin C group and combinations of 240 mg of vitamin E and 120 mg of vitamin C group had
higher values than the other treatment groups. The effect of treatment on the hatchability of fertile
eggs (HFE), hatchability of total eggs (HTE) and embryo mortalities were significant (P≤0.01).
Lower HFE was observed in a combination of 60 mg of vitamin E and 60 mg of vitamin C group.
