摘　　要：本试验旨在探讨肉牛启运前进行抗应激处理对降低肉牛引入后发病的效果,在运输前,对第1批的69头牛进行以肌肉注射科特壮为主的综合用药处理,对第2批的39头牛进行肌肉注射牛支原体灭活疫苗的处理,运输时间分别为32 h和36 h,途中不提供水和任何食物,牛运达后继续观察30 d,记录环境温湿度及发病情况,结果显示几乎肉牛始终都处于热应激的状态中;第1批牛和第2批牛在运达后陆续发病,2批牛分别在运后第9天和第13天前时,试验组均比对照组的累积发病数低,但之后到运后1个月,试验组又均比对照组的累积发病数高;运后第1批牛要比第2批牛的发病率和死亡率分别高1.23%和20.29%。This study was aimed to explore the effect of anti-stress treatment on disease occurrence of the heifers after arrival at feedlots.Before transport,the first batch of 69 heifers were injected intra-muscularily（im） Catosal,while the second bactch of 39 heifers were injected intra-muscularily（im） inactivated Mycoplasma bovis vaccine.The duration of transportation was 32 h and 36 h respectively without providing any water or feed for the heifers during the highway.Observation continued for 30 d after transportation and record the temperature and humidity of the environment as well as morbidity information.The results show that all heifers almost at status of heat stress all the time.The first batch of beef cattle and the second in succession after the arrival of disease,the accumulated morbidities of the two tested groups are lower than that of the two control groups before the ninth day and the thirteenth day respectively after transport in two batches,but later,the accumulated morbidities of the two tested groups are higher than that of the two control groups in two batches;the morbidity and the mortality of the first batch are higher for 1.23% and 20.29% than that of the second batch.
