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.
家畜的繁殖效率对农业生产力和经济可持续性至关重要。成功受精和后代生存能力的一个关键因素是精液质量。冷冻-解冻精液在人工授精（AI）中的质量差已被证明会影响受孕结果，对家畜生产产生负面影响。最近的遗传研究进展已经确定了与各种家畜（如牛、羊、山羊、猪、水牛和马）精液质量特征相关的特定标记。这些遗传标记在筛选用于繁殖的雄性动物的适宜性方面至关重要，这反过来又增强了选择性繁殖计划。了解这些标记对于提高家畜种群的繁殖性能和增加生产力至关重要。这篇综述全面概述了与主要家畜精液质量相关的遗传标记。它探讨了潜在的遗传机制及其在动物繁殖和管理中的实际意义。该综述强调了将遗传见解纳入繁殖策略的重要性，以优化繁殖效率并确保家畜产业的可持续发展。
