养殖与饲料

为明确天然维生素与合成维生素的差异及在动物健康养殖中的应用价值,本文系统检索PubMed、Web of Science、Scopus及Cochrane Library等主流数据库的相关文献，系统梳理两类维生素的功能差异及应用适配性相关研究进展，以维生素对动物机体的核心作用为切入点，重点分析天然与人工合成维生素的理化特性，系统总结了两者在生物利用度、安全性、功能协同性及应用价值方面的核心差异。结果表明，天然维生素具有杂质含量低、稳定性优良、生物安全性更高的特点，在动物机体识别、吸收及利用过程中更具适配性；人工合成维生素虽具备成本低廉、易于规模化生产的优势，但在成分完整性及功能协同效应方面存在明显局限，为精准化动物营养策略制定及健康养殖模式优化提供了参考。

The differences and application adaptability of natural vitamins and synthetic vitamins were studied to provide a reference for promoting the development of healthy farming.The relevant literature in mainstream databases including PubMed, Web of Science, Scopus, and Cochrane Library were retrieved to systematically review the progress on studying the functional differences and application adaptability of natural vitamins and synthetic vitamins. The physicochemical properties of natural vitamins and synthetic vitamins were analyzed by starting from the core role of vitamins in animal bodies. The key differences between natural vitamins and synthetic vitamins were systematically summarized in terms of bioavailability, safety, functional synergy, and application value. Natural vitamins have the characteristics of low impurity, excellent stability, and higher biological safety, making them more adaptable in processes of recognition, absorption, and utilization in animals. Synthetic vitamins have the advantages of low cost and easy for scale production, but have significant limitations in terms of component integrity and functional synergy.The differences and application adaptability of natural vitamins and synthetic vitamins were clarified. It will provide reference for developing precise strategies of animal nutrition and optimizing the models of healthy farming.
