Rumen microbiota-host interactions regulate intramuscular fat deposition in cattle via the alpha-linolenic acid-fatty acid β-oxidation/L-carnitine-MPO axis.

ABSTRACT:

Background

Beef, known for its high protein, low fat, and rich amino acid content, is a premium source of nutrition compared to other meats. As living standards improve, higher demands are being placed on beef quality, which is closely related to intramuscular fat (IMF) content. Jiaxian Red Cattle, a local Chinese breed, is renowned for its high meat quality, characterized by reddish muscle color and snow-white fat. However, the molecular mechanisms underlying differences in intramuscular fat deposition and meat quality in this breed remain unclear. This study aims to explore the potential molecular mechanisms of intramuscular fat deposition in beef cattle using multi-omics approaches.
