Abstract
Herein we attempt to shed light on the potential improving effect of Eruca sativa seeds (ESS) on the reproductive aspects of male Japanese quails. To accomplish this objective, two groups of quails were supplemented with ESS powder at doses of 5 and 10 g/kg feed from 7 days to 140 days of age, in addition to the control group, which did not receive treatment. Forty males were reared singly in cages to evaluate sperm characters and 32 males were raised with 64 females to evaluate fertility and sperm penetrability. Sixty-six phytochemical compounds were found according to gas chromatography-mass spectrometry analysis of ESS. The most plentiful ones are 13-docosenoic acid methyl ester, 9-octadecenoic acid methyl ester, and linoleic acid methyl ester. Both 5 g/kg and 10 g/kg doses of ESS showed similar effectiveness in enhancing various reproductive parameters, including gonadal index, sperm characteristics, fertility, libido, and cloacal gland attributes. However, some aspects like sperm concentration and testosterone levels exhibited a dose-dependent response. There is no significant change in mortality rate of supplemented groups compared to the control one. ESS also caused a reduction in feed intake and an enhancement in feed conversion ratio without affecting final body weight and body weight gain. This suggests potential nutritional benefits beyond reproductive health. The low-dose-fed group showed a significant reduction in total cholesterol and malondialdehyde compared to the high-dose-fed and unfed groups. The higher dose notably increased total antioxidant capacity compared to the lower dose and control group. Despite the positive effects on male reproductive parameters, there wasn't a significant impact on hatchability percentage, indicating that while male fertility improved, it might not have directly affected the viability of the eggs. Overall, the study suggests that ESS could be a safe and promising addition to the diet of male Japanese quails to enhance their reproductive capabilities without adverse effects. The findings could have implications for poultry farming by potentially improving breeding efficiency and health outcomes in quails.
