摘要

To assess the effect of ginger rhizomes essential oil on some reproductive parameters of laying birds, 80 female Japanese quails (Coturnix coturnix japonica) aged 3 weeks and weighing between 120 - 130 g were randomly assigned into 4 dietary treatment groups in a completely randomized design. From 3 till 13 weeks, birds in group 1 (control) received distilled water orally (100 μl/kg body weight), while the other three test groups during the same period, received respectively by gavage 50, 100 and 150 μl of ginger roots essential oil per kg body weight. At 11 weeks old, eight birds per group in each treatment were randomly selected and slaughtered, blood samples collected for analysis. On the other hand, the remaining females were maintained 3 with one untreated male in identical boxes per treatment, for fertility assessment, eggs characteristics and hatchability traits. Throughout the experiment, biochemical parameters, eggs characteristics, fertility and hatchability traits were analyzed. No significant change (p > 0.05) was observed during the experimental period for body and relative ovary weights. Contrary, the relative uterus weight significantly increased (p < 0.05) in dose-dependent manner. The level of serum total proteins, LH, FSH and estradiol significantly increased (p < 0.05) in a dose-dependent manner. Also, fertility, hatchability of fertile eggs, total hatchability and chick’s weight significantly increased (p < 0.05) in birds received 100 and 150 μl/kg b.w compared to those of control group. On the other hand, embryonic mortality decreased significantly (p < 0.05) whatever the ginger rhizomes essential oil dose. It was concluded that ginger rhizomes essential oil enhances bird reproductive performances, proteins and reproductive hormone levels and hatchability traits in treated female quails.
