During the transition period and early lactation of ruminants with higher production, the reproductive organs are exposed to various stressors, like inflammation stimulators such as lipopolysaccharides (LPS), as a consequence of high concentrate consumption. In this study, we aimed to determine the probable potential of α-linolenic acid (ALA) in alleviating LPS-induced effects in ovine oocytes in vitro as well as the underlying controlling mechanisms. Different concentrations of LPS (0, 0.

This study aimed to investigate the effect of LPS on oocyte maturation and subsequent development in vitro. Ovine cumulus oocyte complexes (COCs) were matured in a medium supplemented with 0 (control), 0.

- Defective sperm can lead to fertilization issues, making optimal semen storage crucial for maintaining viability, and this study assesses the impact of zinc (Zn) nanoparticles as antioxidants during semen processing and cryopreservation in bulls.
- The research involved 32 ejaculates from Holstein bulls, which were treated with varying concentrations of Zn nanoparticles during semen dilution, leading to improved plasma membrane integrity and mitochondrial activity in treated sperms, although no significant changes were noted in overall sperm motility or DNA fragmentation.
- While the addition of Zn nanoparticles enhanced certain sperm quality markers, it didn't negatively impact embryo development rates during in vitro fertilization, suggesting a potential benefit for using Zn nanoparticles to improve semen quality without compromising reproductive outcomes.
