The effects of various concentrations of polygonum hydro-alcoholic extract on specific indices of sperm fertility in rooster

Medicinal Plants with antioxidant properties can improve the quantitative and qualitative specific indices of sperm fertility and increase the hatchability rate in rooster by disturbing the production process of free radicals and neutralizing of oxidative stress. The aim of this study was to investigate the effect of various concentrations of ginger extract on biological parameters and specialized indices of sperm fertility in Golpaygani roosters. In this study, hydro-alcoholic extract of polygonum plant was prepared at concentrations of 0, 500, 1000 and 2000 mg/L and was added to drinking water of 36 adult male (32 weeks old) Golpaygani cock. After one week, the effect of different concentrations of the extract on the specific indices of sperm fertility (SMI, FSC, PMSCa, PMSCb and MSC) were evaluated and compared. The papenicular staining was also used to specific evaluation of sperm abnormalities. The use of polygonum extract significantly improved the sperm fertility indices. The most number of sperm with fast progressive movements (PMSCa), the highest levels of SMI, FSC and MSC indices, the least structural and motility abnormalities was demonstrated in 1000 and 2000 mg extract (P≤0.05). Significant differences were not observed between the two above-mentioned intermediate and high concentrations in some parameters (P> 0.05). There was no significant difference in above indices between medium and high concentrations of extract (P>0.05). In conclusion, polygonum , due to the high amounts of antioxidant compounds, significantly increases the sperm indices and also improves the specific parameters of sperm fertility in rooster.
