This work aimed to investigate how two different types of forage (saline and alkaline) impact the meat quality and muscle metabolism of Tibetan sheep. An integrative multi-omics analysis of meat quality and different metabolites was performed using untargeted and targeted metabolomics approaches. The research results indicated that GG grass (saline and alkaline forage) possessed superior characteristics in terms of apparent quality and secondary metabolite content compared with HG grass (Non saline alkali forage), regardless of the targeted metabolites or non-targeted ones. Simultaneously, under stress conditions, the carbohydrates-rich salt-alkali grass play a significant role in slowing down the decline in pH, increasing the unsaturated fatty acid content and reducing the thawing loss in Tibetan sheep. This study provides an understanding of the impact of different salt-alkali grass on the quality of Tibetan sheep meat, while providing a scientific basis for the future development of salt-alkali livestock industry.
本研究旨在探讨两种不同类型的草料（盐碱地草料和非盐碱地草料）如何影响藏羊肉品质和肌肉代谢。采用非靶向和靶向代谢组学方法，对肉质和不同代谢物进行了综合多组学分析。研究结果表明，无论靶向代谢物还是非靶向代谢物，与HG草（非盐碱地草料）相比，GG草（盐碱地草料）在表观质量和次生代谢物含量方面具有更优特性。同时，在应激条件下，富含碳水化合物的盐碱地草在减缓藏羊pH值下降、增加不饱和脂肪酸含量和减少解冻损失方面发挥着重要作用。本研究有助于了解不同盐碱地草对藏羊肉品质的影响，同时为盐碱地畜牧业的未来发展提供科学依据。
