Abstract: As toxic fungal secondary metabolites,mycotoxins are ubiquitously present in agroecosystems,with their contamination in crops and feed materials has emerged as a global threat to food safety.These compounds exhibit well-characterized hepatotoxic,carcinogenic,teratogenic,immunotoxic,and neurotoxic properties,posing substantial risks to human and animal health.Mycotoxins severely impair the physiological homeostasis of reproductive system in sows through multi-pathway disruptions,leading to infertility,abortions and other reproductive disorders.Therefore,elucidating the mechanisms underlying their reproductive toxicity is critical for mitigating breeding-associated risks and developing targeted prevention strategies.This review systematically summarizes the classification of major mycotoxins and their contamination profiles in Chinese raw materials and feed.Mycotoxins enter sows through contaminated feed,inducing multi-level impairments including ovarian dysfunction,uterine developmental anomalies,and dysregulation of reproductive endocrine homeostasis.The review provides a molecular-level analysis of mycotoxin-induced damage mechanisms associated with follicular developmental disorders,oocyte maturation defects,and regulation of granulosa cell apoptosis through specific signaling pathways.Regarding mitigation technologies,the article integrates diversified detoxification strategies including physical adsorption,chemical degradation,and microbial biotransformation,and proposes a systematic framework.By elucidating the reproductive toxicological effects of mycotoxins and their intervention nodes from multi-faceted analysis,so as to provide a critical theoretical foundation for establishing a comprehensive prevention system against sow reproductive disorders.
