Abstract:

Fat content is one of the main factors affecting the quality of livestock meat. The distribution of fat in muscles is closely related to the color, palatability, flavor, tenderness and hydration of meat, and intramuscular fat is regarded as a key indicator for evaluating meat quality. Intestinal microbiota and mitochondria, as the largest microecosystem and cellular "power factories" in the body, play important bridging roles between lipid metabolism and cellular metabolism. At present, research on the gut microbiome and mitochondria is relatively extensive, but the impact of their interaction on fat deposition is not yet clear. This article reviews the research on gut microbiota and their metabolite functions and fatty acid metabolism, fat deposition and mitochondrial function, as well as the regulatory mechanisms of gut microbiota and their metabolite interactions with mitochondria on fat deposition, in order to provide references and ideas for improving animal meat quality through gut microbiota and mitochondria.

Key words: gut microbiota, mitochondria, metabolite, fat deposition
