核苷酸的生物学功能及其在动物生产中的应用OA

As the fundamental structural unit of nucleic acids,nucleotides constitute the molecular basis for the storage and transmission of genetic information.Beyond this foundational role,they are extensively involved in diverse and critical physiological processes,including energy metabolism,coenzyme synthesis,cellular signal transduction,intestinal health maintenance,and immune function regulation.Recent research indicates that the strategic administration of nucleotides can effectively enhance the growth and reproductive performance of animals,improve meat quality,promote intestinal microecological balance,strengthen the intestinal barrier function,and elevate the organism′s overall stress resistance.This review first outlines the general properties and biological functions of nucleotides.It then systematically synthe-sizes current research progress on their application in animal production,detailing the observed effects and elucidating the underlying mechanisms of action.Finally,it discusses existing challenges and gaps in the current research landscape.The aim is to provide a consolidated reference to inform the rational and targeted application of nucleotides in the context of sustainable animal production and precision nutrition.
