Abstract： Transport stress is a significant factor affecting cattle health and production performance， involving disruptions in multiple physiological systems such as metabolism，digestion，endocrinology ， and immunity. During transportation， various stressors （such as fasting，dehydration，temperature fluctuations， overcrowding，and loading/unloading） can negatively impact cattle physiological functions，leading to the excessive production of stress hormones and changes in rumen microbial community abundance. This，in turn，reduces immune function and antioxidant capacity，causes tissue and organ damage，and ultimately affcts overall health and production performance. This reviewsummarizes the mechanisms underlying physiological imbalances in cattle caused by transportation stress， aiming to provide theoretical references for identifying target points for controlling transportation stress in cattle and improving animal welfare during transportation.
