Background And Aim: In the global pig farming industry, artificial insemination (AI) is widely used to propagate high-quality genetics using processed semen that can be stored for extended periods. However, boar sperm are particularly susceptible to oxidative damage during storage and cryopreservation because of their high polyunsaturated fatty acid content. This study aimed to systematically review the impact of resveratrol (RVT), a potent antioxidant, on the preservation of boar semen.
Materials And Methods: A comprehensive meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant articles were retrieved from databases such as Scopus, ScienceDirect, and PubMed using specific keywords. After a thorough screening, 10 studies were selected for inclusion. Data extracted from these studies included parameters such as sperm motility, viability, DNA integrity, and lipid peroxidation levels.
Results: Resveratrol supplementation in boar semen extenders significantly improved sperm quality under various storage conditions, including waterbath and cooled and frozen semen. RVT's antioxidative properties effectively reduced reactive oxygen species and prevented oxidative stress-related damage to sperm cells.
Conclusion: The addition of resveratrol to semen extenders enhances the preservation of boar sperm by mitigating oxidative damage, potentially increasing the success rate of AI in the swine industry. This study highlights the need for further research to optimize RVT dosage and application methods for different semen preservation techniques.

Cryopreservation of boar semen is essential for maintaining genetic diversity and improving reproductive efficiency. However, optimizing semen extenders and packaging methods is crucial to enhancing sperm quality and cryotolerance. Equex-STM is commonly used as a surfactant to enhance cryoprotective properties by stabilizing sperm membranes during freezing and thawing.

Preservation of porcine semen is essential for artificial insemination and genetic improvement in pig breeding programs. However, the overproduction of reactive oxygen species (ROS) and lower levels of protein phosphorylation emerge as two challenges during semen preservation. Inspired by the innate ligand-receptor binding biofunction of dopamine, herein, a dual-task nano-protectant that combines ROS-scavenging and protein phosphorylation-regulating properties via incorporating the natural antioxidant epigallocatechin gallate (EGCG) into polydopamine nanoparticles (EGCG@PDA NPs) was proposed to enhance the quality of pig semen during storage at 4 ℃.

Porcine breeding industries typically ensure the viability of boar artificial insemination doses during a 5-day liquid storage period at 17 °C. This study aimed to investigate whether the addition of L-carnitine (LC) to boar semen doses on different days of cooled storage could extend their usability. In experiment 1, LC was added to porcine semen doses on the fifth day (d5) of cooled storage performing five treatments control (no LC), 0.

Metabolomic analysis of boar semen associated with sexual maturation is essential for improving fertility management and breeding, with amino acids and amines playing key roles in the reproductive process. This study aimed to explore changes in amino acids and amines in boar spermatozoa and seminal plasma during puberty to sexual maturity and identify potential biomarkers of sexual maturity. Semen was collected from the same 15 Duroc boars over time at approximately 7 months (Age 1), 8.
