Semen Quality Management in Boar Reproduction
Summary
Effective management of boar semen quality underpins reproductive efficiency in commercial pig production and genetic improvement programmes. Semen quality is assessed through a suite of parameters including ejaculate volume, sperm concentration, motility, viability and DNA integrity. These metrics are influenced by intrinsic factors such as breed, age and genetic background, and by extrinsic factors including nutrition, season, photoperiod and environmental stressors. Nutritional strategy and antioxidant supplementation have emerged as key interventions to counteract oxidative damage and support sperm function. Continuous monitoring using novel biomarkers—such as the sperm nuclear DNA fragmentation index—and an understanding of cellular signalling pathways in testicular and sperm physiology enable tailored interventions. Adoption of these tools and practices enhances fertile lifespan of boars, optimises insemination success and delivers economic and welfare benefits across diverse production systems worldwide.

Semen Quality Management in Boar Reproduction publication trend
The graph below shows the total number of articles in semen quality management in boar reproduction across all publications each year (not limited to Nature Index journals).
Technical terms
Sperm motility: The capacity of spermatozoa to move actively and progressively, a key predictor of fertilisation potential.
Oxidative stress: Imbalance between reactive oxygen species production and antioxidant defence, leading to cellular damage in sperm cells.
DNA fragmentation index (DFI): Proportion of spermatozoa exhibiting breaks in nuclear DNA, reflecting genomic integrity and fertility potential.
mTOR signalling pathway: A nutrient-responsive kinase cascade regulating cell growth and protein synthesis, implicated in testis development and spermatogenesis.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
