This study was to determine differences in the global metabolic profiles of serum and urine of Xuanhan yellow cattle, Simmental crossbred cattle (Simmental × Xuanhan yellow cattle), and cattle-yaks (Jersey × Maiwa yak) under heat stress (temperature–humidity index remained above 80 for 1 week). A total of 55 different metabolites associated with the three breeds were identified in the serum and urine samples by gas chromatography–mass spectrometry. The metabolic adaptations to heat stress are heterogeneous. Cattle-yaks mobilize a greater amount of body protein to release glucogenic amino acids to supply energy, whereas the tricarboxylic acid cycle is inhibited. Simmental crossbred cattle mobilize a greater amount of body fat to use free fatty acids as an energy source. In comparison with Simmental crossbred cattle and cattle-yaks, Xuanhan yellow cattle have higher glycolytic activity and possess a stronger antioxidant defense system and are, in conclusion, more adapted to hot and humid environments.

三种牛肉品种的血清和尿液代谢组学分析揭示了不同水平的热应激耐受性

本研究旨在确定在高温（温度-湿度指数保持不变）下宣汉黄牛，西门塔尔杂交牛（西门塔尔×宣汉黄牛）和牛cattle牛（泽西×迈瓦wa牛）的血清和尿液的整体代谢谱差异。 80以上1周）。通过气相色谱-质谱法在血清和尿液样品中鉴定出与这三个品种相关的总共55种不同的代谢产物。对热应激的代谢适应是异质的。牛-牛可动员更多的人体蛋白质释放葡萄糖原氨基酸以提供能量，而三羧酸循环则受到抑制。西门塔尔杂种牛动员了更多的体内脂肪，以利用游离脂肪酸作为能源。与西门塔尔杂交牛和cattle牛相比，
