摘　　要：优质饲草是现代草食畜牧业健康、高质量发展的重要基础保障,也是维持优质、安全畜产品持续稳定生产的重要前提。草产品的精细加工、稳定贮存和高效利用是“饲草”向“畜产品”转化的关键步骤。通过系统解析饲草本底的生物学特性,贮存过程中微生物的组成、演替与代谢规律,功能微生物组调控牧草营养转化路径与利用机制,以及“微生物—发酵饲草料—草食家畜—畜产品”全生物链提质增效与安全调控机理,对于提升草产品品质与安全性、提高饲草利用率与转化率,推动我国饲草产业和草食畜牧业高质量发展,实现草食畜牧业提质增效等方面具有重要意义。High-quality forage is a vital foundational guarantee for the healthy and high-quality development of modern herbivorous livestock husbandry.It also serves as a crucial prerequisite for maintaining stable production of premium and safe animal products.The refined processing,stable storage,and efficient utilization of forage products are pivotal stages in the transformation from“forage”to“animal products.”Systematically clarifying the biological characteristics of forage substrates,microbial composition,dynamic succession and metabolic patterns during the fermentation and storage,as well as understanding the nutritional transformation and utilization pathways regulated by functional microbial communities,are of paramount importance.Additionally,comprehending the enhancement and safety mechanisms of the entire chain involving“microbe-fermented forage-herbivorous livestock-animal products”is also very crucial.These efforts will contribute to improving the quality and safety of forage products,enhancing utilization and conversion rates of forage,promoting high-quality development in Chinas forage industry and herbivorous livestock farming,and achieving advancements in the quality and efficiency of herbivorous livestock husbandry.
