The reproductive efficiency of livestock is crucial for agricultural productivity and economic sustainability. One critical factor in successful fertilization and the viability of offspring is the quality of semen. Poor semen quality, especially in frozen-thawed semen used in artificial insemination (AI) have been shown to influence conception outcomes, resulting a negative impact on livestock production. Recent advancements in genetic research have identified specific markers linked to semen quality traits in various livestock species, such as cattle, sheep, goats, pigs, buffalo, and equines. These genetic markers are essential in screening males for breeding suitability, which in turn enhances selective breeding programs. Understanding these markers is crucial for improving reproductive performance and increasing productivity in livestock populations. This review offers a comprehensive overview of the genetic markers associated with semen quality in key livestock. It explores the underlying genetic mechanisms and their practical implications in animal breeding and management. The review underscores the importance of integrating genetic insights into breeding strategies to optimize reproductive efficiency and ensure the sustainable development of livestock industries.

Semen quality traits, including sperm morphology, sperm shape, sperm count, ejaculate volume, low percentage of motile spermatozoa in semen, and motility, play a crucial role in male reproductive efficiency and fertilization success. This review article highlighted the impact of genetic polymorphisms in genes on semen quality and fertility traits in mammalians. Single nucleotide polymorphisms (SNPs) in these genes were associated with various sperm abnormalities, such as abnormal sperm flagella morphology, reduced motility, impaired DNA integrity, altered antioxidant status, disrupted sperm head–tail junction, spermatogenesis defects, reduced testicular size, and a range of sperm disorders. This comprehensive review of the available literature offers significant insights into the genetic factors influencing semen quality traits, which can contribute to the development of genetic markers and the enhancement of male fertility through assisted selective breeding programs.
