“…More positive effect on semen quality and preservability is detected with poor quality semen (Pour et al, 2013). Significant positive effect was also reported in chicken semen fortified with Vitamin E at the rate of 2% (Tabatabaei et al, 2011). The beneficial effect of Vitamin E on sperm motility was previously also observed (Boonsorn et al, 2010).…”

Present study was aimed to improve poor quality crossbred bulls semen, as occurrence of poor quality ejaculates are one of the major problems in crossbred bulls. Antioxidants and its combination was tried to overcome such problems. Vitamin E, Vitamin C and Vitamin E+C were supplemented at dose rate of 1mg, 5 mM and 1mg + 5mM per ml respectively in split ejaculates to evaluate semen quality during preservation at refrigerated temperature and cryopreservation. The results showed that semen characteristics were better in antioxidant supplemented ejaculates. Total sperm abnormality were significantly lower (p<0.05) in antioxidant supplemented group. The seminal characteristics of crossbred bull semen showed significantly better (p<0.05) performance on preservation, when fortified with Vitamin E as compared to Vitamin C alone as well as Vitamin E and C in combination. The performance of semen additives, were supportive to semen characteristics especially for Vitamin E, moreover fortification with Vitamin E+C was slightly superior to Vitamin C. It can be concluded that fortification of Vitamin E has beneficial role in semen quality improvement followed by Vitamin E+C and Vitamin C.

“…These vitamins deactivate reactive oxygen species and prevent the propagation of lipid peroxidation by scavenging lipid peroxyl radicals in cell membranes (Brewer, ) thereby reducing the detrimental effect of reactive oxygen species on motility and livability (Budai, Egerszegi, Olah, Javor, & Kovacs, ), hence the reduced post‐thaw percentage abnormality and increased percentage livability observed in spermatozoa cryopreserved with TNM. The findings agreed with Tabatabaei, Roozali, and Esmail (), Al‐Amoudi () and Ekaluo, Ikpeme, Ibiang, and Amaechina () that vitamin C and E reduced oxidative stress and consequently beneficial effects on sperm motility, viability and reduced morphological defects during storage of semen in extenders supplemented with these vitamins. Furthermore, Azawi and Hussein () reported that the addition of antioxidants such as vitamin C and E to semen preservation media improved longevity and quality of cooled mammalian sperm cells.…”

Contents Comparative effect of slow and rapid freezing on sperm functional attributes and oxidative stress parameters of goat spermatozoa cryopreserved with tiger nut milk (TNM) extender was examined in this study. Pooled semen samples obtained from West African Dwarf (WAD) goat bucks were diluted with Tris‐based extenders containing different levels of TNM (0, 5, 10, 15 and 20 ml/100 ml extender). The diluted semen samples were subjected to slow and rapid freezing for a period of 7 days and thereafter evaluated for sperm functional attributes (percentage motility, acrosome integrity, membrane integrity, abnormality and livability) and oxidative stress (malondialdehyde [MDA] concentration and acrosin activity) parameters. Results showed that higher (p < 0.05) motility, livability, membrane and acrosome integrities in semen cryopreserved with slow freezing compared to rapid freezing. These parameters (motility, livability and membrane integrity) were higher (p < 0.05) in semen cryopreserved with 15% TNM in both slow and rapid freezing protocols. The results revealed that semen cryopreserved in slow freezing had lower (p < 0.05) abnormality compared to rapid freezing. Acrosin activity was higher in slow freezing compared to rapid freezing. Acrosin activity was higher at 15% TNM in both slow and rapid freezing. Lower (p < 0.05) MDA concentration was observed in semen cryopreserved using slow freezing compared to rapid freezing. The findings revealed improved post‐thaw sperm functional attributes and oxidative stress parameters of WAD goat spermatozoa cryopreserved with 15% TNM using slow freezing.

“…To collect cocks divergent in sperm motility for sequencing, sperm motility estimation was performed 10 times, at a 2-day interval, in 396 Beijing-you male breeders since 40 wk of age. Sperm motility was estimated by microscopic observation (×400 magnification) 43 , expressed as the number of motile spermatozoa with moderate to rapid progressive movement of 10. Based on the averaged sperm motility, 15 highest and 15 lowest phenotypes were selected at 45 wk of age to be used as semen donor to inseminate the females.…”

Sperm motility is the most important indicator in evaluating roosters’ fecundity. However, the genetic mechanisms underlying chicken sperm motility is not yet clear. Long non-coding RNA (lncRNA) play epigenetic roles in reproduction. In this study, RNA sequencing was employed to profile the testis transcriptome (lncRNA and mRNA) of six Beijing-you cocks divergent in sperm motility. In total, 2,597 lncRNAs were identified in the chicken testis, including 1,267 lincRNAs, 975 anti-sense lncRNAs, and 355 intronic lncRNAs. They shared similar features with previous studies. Of these lncRNAs, 124 were differentially expressed. Among 17,690 mRNAs detected in this study, 544 were differentially expressed, including a bunch of genes with known functions on sperm motility. GO annotation analysis revealed these genes were involved in ATP binding, cilium assembly, and oxidation-reduction processes. Integrating analysis of lncRNA and mRNA profiles predicted 10 lncRNA-gene pairs, including 8 co-regulated and 2 inversely-regulated pairs. To the best of our knowledge, this is the first genome-wide investigation of the lncRNAs in the chicken testis associated with sperm motility. Our results provided a catalog of chicken testis lncRNAs and genes worthy of further studies to understand their roles in cocks’ reproductive performance regulation.
