目的：有关青贮饲料维生素含量的信息有限。本研究探讨了添加或不添加乳酸菌菌剂的苜蓿和羊草青贮饲料中维生素含量的变化。方法：收获初花期的苜蓿和盛花期的羊草。每种饲料类型的处理均为对照（仅去离子水）和 1x10(6) 菌落形成单位植物乳杆菌 (LP)/g 新鲜物质。青贮45天后，对所有青贮饲料进行取样，评价其维生素含量、发酵品质和化学成分。结果：LP接种剂显着降低了苜蓿和羊草青贮饲料的pH值和氨氮含量（p
Objective: Information regarding the vitamin content of silage is limited. This study investigated the changes in the vitamin content of alfalfa and Chinese leymus silages with or without a lactic acid bacterial inoculant.Methods: Alfalfa at the early flowering stage and Chinese leymus at the full-bloom stage were harvested. The treatments for each forage type were control (deionized water only) and 1x10(6) colony-forming units Lactobacillus plantarum (LP)/g fresh matter. After 45 days of ensiling, all silages were sampled for evaluating the vitamin content, fermentation quality and chemical composition.Results: The LP inoculant decreased the pH value and ammonia nitrogen content of the alfalfa and Chinese leymus silages and significantly (p
