摘要: Colostrum from yaks and buffaloes possesses substantial nutritional value, yet the complete array of metabolites within remains insufficiently elucidated. This study scrutinizes the metabolite profiles of yak, buffalo, and cow colostrum utilizing targeted metabolomics paired with ultra-performance liquid chromatography-tandem triple quadrupole linear ion trap mass spectrometry (UPLC-QTRAP-MS). The analysis detected 362 metabolites across all samples. Furthermore, 63, 77, and 46 differential metabolites were selected between yak and buffalo colostrum, yak and cow colostrum, and buffalo and cow colostrum, respectively. Yak colostrum notably contained higher concentrations of inositol, glycine, and carnitine, whereas buffalo colostrum was distinguished by a substantial presence of primary bile acids, which facilitate fat digestion. These findings offer profound insights into yak and buffalo colostrum, providing critical data to propel advancements in the dairy industry.
