Abstract: This paper reports the results of using Thiofentanil for immobilisation of Budorcas taxicolor.A total of 11 B.taxicolor are immobilised 21 times (Table 1 ) . Dosage rates varing from 4.7 to 16μg/kg are successfully used.The average dosage is 11.6μg/kg.Thiofentanil induces relatively short induction time due to its powerful and rapid absorption.Induction time ranges from 1 to 7 minutes.The average induction time is 2.4 min.Very little excitement is noticed during the induction phase.The induction phase usually terminates in analgesic narcosis, characterised by sternal or lateral recumbency.The immobilisation time is over 1.5 hours.Respiratory depression is mild and no death occurs in this trials. The action of Thiofentanil can rapidly and effectively be reversed with the usual Morphine antagonist Nalorphine.The recovery time ranges from 1 to 11 min. and the average time 2.9 min,The results show that Thiofentanil is considered to be a powerful, safe and effective Morphine-like analgesic immobiliser.So we suggest that Budorcas taxicolor can be immobilised by using Thiofentanil with the optimal dosage of 10μg/kg.
