| Abstract |
Objective
Semen cryopreservation is an effective method of preserving genetic material, particularly in native chicken breeds facing a substantial decline. In this study, we evaluated the quality of frozen/thawed rooster semen treated with different concentrations of oral administrations of black ginger (Kaempferia parviflora: KP) extract and determined its fertility. Methods: Thirty-two Thai native roosters (Pradu Hang Dum, 42 weeks old) were used in this study. The treatments were classified into four groups according to the concentration of KP extract administered to the roosters: 0, 100, 150, and 200 mg/kg body weight. The quality of fresh semen was analyzed before cryopreservation. Post-thaw sperm quality and fertility potential were determined. Also, lipid peroxidation was determined.
Results
The results showed that sperm concentration and movement increased in roosters treated with 200 mg/kg of KP extract (P<0.05). The malondialdehyde (MDA) in the rooster receiving 200 mg/kg KP extract was lower than that in the other but had an insignificant difference within the KP treatment groups (P>0.05). The highest MDA levels were observed in the control group (P<0.05). The percentage of motile sperm (total motility and progressive motility) after semen thawing was higher in roosters that received 150 and 200 mg/kg KP extract than in those that received 100 mg/kg KP extract and the control (P<0.05). MDA levels decreased significantly in roosters that received 150 and 200 mg/kg KP extract than in those that received 100 mg/kg KP extract and the control (P<0.05). Fertility and hatchability were greater in the KP150 and KP200 groups than in the KP100 and control groups (P<0.05).
Conclusion
The optimal amount of KP extract influencing initial sperm quality was determined to be 200 mg/kg. However, 150 mg/kg was the optimal low dosage of KP extract administration that maintained sperm quality and fertility following semen cryopreservation.
