摘　　要：肉用犊牛在转至育肥场会出现一系列的应激反应,对肉牛育肥产业带来极大损失,本文通过对犊牛运输应激及断奶应激全面剖析的基础上,对产生犊牛应激综合征提出了新的看法,并提出要从犊牛的心理、断奶、环境改变、饲草料变化和运输等方面所产生的一系列应激叠加角度上考虑,综合预防犊牛过渡应激的横发,降低犊牛应激综合征给肉牛生产造成的损失。A series of stress reactions will occur during beef calves transferred to the fattening yard,which will bring great losses to beef cattle fattening industry.Based on the comprehensive analysis of calf transport stress and weaning stress,this paper puts forward a new view on the generation of calf stress syndrome,and proposes a series of stress superposition from the aspects of calves'psychology,weaning,environmental changes,forage changes and transportation to comprehensively prevent the outbreak of excessive stress in calves,which would reduce the losses caused by calf stress syndrome to beef cattle production.
