Microbiome-proteome analysis of gastrointestinal microbiota and longissimus thoracis muscle proteins in cattle with high and low grades of marbling.

ABSTRACT: Marbling is a key indicator of the meat quality of ruminants. Gastrointestinal microbiota may regulate the formation of marbling by influencing the nutritional metabolism of animals. This study analyzed the composition and functional differences of microbiota in the rumen and cecum, the differences in volatile fatty acids (VFAs) content in the longissimus thoracis muscle, and the differences in protein abundance in the longissimus thoracis muscle of ruminants with different marbling grades through microbiome-proteome analysis. The results showed that the diversity of gastrointestinal microbiota in high-marbling ruminants was significantly higher than that in low-marbling ruminants. The relative abundance of Firmicutes and Akkermansia in the gastrointestinal of high-marbling ruminants was h
