Cysteine improves boar sperm quality via glutathione biosynthesis during the liquid storage [PDF]
Animal Bioscience, 2022 Objective Sperm is particularly susceptible to reactive oxygen species (ROS) stress. Glutathione (GSH) is an endogenous antioxidant that regulates sperm redox homeostasis.

Reducing the Glucose Level in Pre-treatment Solution Improves Post-thaw Boar Sperm Quality
Frontiers in Veterinary Science, 2022 Frozen–thawed boar sperm was not widely used in pig artificial insemination as the sperm quality was damaged by biochemical and physical modifications during the cryopreservation process.

Sperm function and mitochondrial activity: An insight on boar sperm metabolism [PDF]
Theriogenology, 2020 In this study boar sperm mitochondrial activity was studied and deepened in order to delineate the main metabolic strategies used by boar sperm to obtain energy and to link them to sperm function. Boar spermatozoa were collected, diluted at 30 × 106 spz/mL and incubated for 1 h with: Rotenone (ROT), complex I inhibitor, Dimethyl-malonate (DMM), complex

A novel experimental design for boar sperm cryopreservation
Journal of Animal Science, 2022 AbstractCryopreservation of sperm is a routine technology in many livestock species, but not in swine. Frozen sperm must result in acceptable conception rates and produce 11 to 12 piglets/litter to be competitive with traditional cooled semen. The development of an extender that results in high post-thaw sperm quality and acceptable litter size ...

Sperm capacitation as a predictor of boar fertility
Molecular Reproduction and Development, 2023 AbstractPrediction of a boar's fertility level has great economic importance for sow herds. After standard sperm morphology and motility metrics are met, approximately 25% of boars have less than 80% conception rates. Due in part to the many factors involved in the fertilization process, a multifactorial model incorporating multiple relevant sperm ...

Effect of zinc on boar sperm liquid storage. [PDF]
Front Vet Sci, 2023 Storage and transport of liquid boar sperm for artificial insemination (AI) requires the addition of solutions called extenders, which increase the volume of the ejaculate and help preserve its functional characteristics. Yet, the quality of sperm decreases over time primarily due to the increased production of reactive oxygen species (ROS) that damage
