Deoxynivalenol contamination in feed and food, pervasive from growth, storage, processing, poses a significant risk to dairy cows, particularly when exposed high-starch diet; however, whether diet exacerbates these negative effects remains unclear. Therefore, we investigated the combined impact of deoxynivalenol dietary starch on production performance, rumen function, health cows using metabolomics 16 S rRNA sequencing. Our findings suggested that both high- low-starch diets contaminated with significantly reduced concentration propionate, isobutyrate, valerate, total volatile fatty acids (TVFA), microbial crude protein (MCP) concentrations, accompanied by noteworthy increase NH
