摘要： Yaks (Bos grunniens) are a critical livestock breed in the plateau region, and changing the feeding system of yaks can significantly improve their growth performance. The effects of different feeding regimes on the growth performance and meat quality of yaks were comprehensively compared here. The transcriptome and proteome of the Longissimus dorsi muscle were determined using RNA-seq and Tandem Mass Tag (TMT) techniques. Indoor feeding significantly improved the growth performance (such as the average daily gain and carcass weight) and meat quality characteristics compared with traditional grazing feeding. In the grazing (Group G) vs. in-house fed group (Group HF) comparison, 40 differentially expressed genes/differentially abundant proteins exhibited the same mRNA and protein expression trends. These genes were associated with collagen binding, the lipoxygenase pathway, and the arachidonic acid metabolic process. Parallel reaction monitoring verified whether the TMT results were reliable. Moreover, some pathways, such as the AMPK signaling pathway, FoxO signaling pathway, PPAR signaling pathway, and fatty acid metabolism, were significantly enriched. These results expand our knowledge about meat quality in yaks and provide practical information and more evidence for further insight into the biological mechanisms underlying meat quality traits.
