摘要

高效的公猪繁殖管理对于全球猪肉产业的可持续性和生产力至关重要。现代人工授精（AI）育种计划大大受益于先进的选育方法和生物标志物的整合，以提高公猪的繁殖性能。传统的选育方法完全依赖于公猪的表型，如生长速度和体型，而现代种猪育种已越来越多地转向分子和遗传工具，这些工具仍然是表型特征的补充。这些方法包括基因组学、转录组学和蛋白质组学。生物标志物是公猪繁殖能力的关键指标。它们有助于识别繁殖力超强的个体，并帮助早期识别潜在的繁殖力问题，从而采取积极的管理策略。本综述总结了与公猪精液质量、精子功能和整体繁殖能力相关的各种生物标志物的现有知识。此外，我们还探讨了先进技术及其在发现预测公猪繁殖力的新型选择方法和生物标志物方面的潜在应用。全面了解公猪繁殖能力的选择标准和生物标志物对于制定有效的育种计划以提高猪的繁殖性能至关重要。

Selection and direct biomarkers of reproductive capacity of breeding boars

Efficient management of pig reproduction is paramount for the sustainability and productivity of the global pork industry. Modern artificial insemination (AI) breeding programs have greatly benefited from the integration of advanced selection methods and biomarkers to enhance the reproductive performance of boars. While traditional selection methods have relied soley on boar phenotype, such as growth rate and conformation, modern pig breeding has shifted more and more toward molecular and genetic tools, which are still complemented by phenotypic traits. These methods encompass genomics, transcriptomics, and proteomics. Biomarkers serve as critical indicators of boar reproductive capacity. They can help to identify individuals with superior fertility and aid in the early identification of potential fertility issues, allowing for proactive management strategies. This review summarizes current knowledge of various biomarkers associated with semen quality, sperm function, and overall reproductive fitness in boars. Furthermore, we explore advanced technologies and their potential applications in uncovering novel selection methods and biomarkers for predicting boar fertility. A comprehensive understanding of selection criteria and biomarkers governing boar reproductive capacity is essential for developing effective breeding programs to enhance swine reproductive performance.

期刊介绍： Animal Reproduction Science publishes results from studies relating to reproduction and fertility in animals. This includes both fundamental research and applied studies, including management practices that increase our understanding of the biology and manipulation of reproduction. Manuscripts should go into depth in the mechanisms involved in the research reported, rather than a give a mere description of findings. The focus is on animals that are useful to humans including food- and fibre-producing; companion/recreational; captive; and endangered species including zoo animals, but excluding laboratory animals unless the results of the study provide new information that impacts the basic understanding of the biology or manipulation of reproduction. The journal''s scope includes the study of reproductive physiology and endocrinology, reproductive cycles, natural and artificial control of reproduction, preservation and use of gametes and embryos, pregnancy and parturition, infertility and sterility, diagnostic and therapeutic techniques. The Editorial Board of Animal Reproduction Science has decided not to publish papers in which there is an exclusive examination of the in vitro development of oocytes and embryos; however, there will be consideration of papers that include in vitro studies where the source of the oocytes and/or development of the embryos beyond the blastocyst stage is part of the experimental design.
