2019年4月23日，欧盟食品安全局（EFSA）发布关于一种含有酿酒酵母NBRC 0203、植物乳杆菌NBRC 3070和干酪乳杆菌NBRC 3425的技术添加剂（青贮添加剂）用于所有动物品种有效性评估的结果。
据了解，有证据显示，干物质含量在30%至70%之间的饲料材料有氧稳定性有所提高。但是，欧盟动物饲料添加剂和产品（FEEDAP）研究小组仍然无法确定产品的最低规格或最低有效剂量。
部分原文报道如下：
The product under assessment is a preparation containing single strains of Saccharomyces cerevisiae, Lactobacillus plantarum and Lactobacillus casei to be used as a technological additive to improve the ensiling process. EFSA has been previously requested by the European Commission to evaluate this product. The safety of the additive for consumers, users, the environment and target animals was established at that time. There was, evidence for improved aerobic stability in forage materials with dry matter contents varying between 30% and 70%. Fluorescence in situ hybridisation methods were also introduced and a different culture medium to better characterise the additive but the Panel on Additives and Products or Substances used in Animal Feed （FEEDAP Panel） remains unable to identify a minimum specification for the product or a minimum effective dose.
