Abstract:In order to investigate the source and direction of cattle and sheep transferred from other provinces in Hunan Province,the market chain was investigated through the "Muyuntong" platform from 2022 to 2023.The results showed that a total of 15 030 batches of 338 700 heads cattle were transferred from outside Hunan Province,and a total of 5 964 batches of 1 170 500 heads cattle were transferred from outside Hunan Province,involving 27 provinces,113 100 cattle and 76 500 sheep were transferred from outside the province for further breeding.There were 74 300 cattle and 16 900 sheep from bruceopathy immune areas.The national transport policy was not strictly enforced in some areas.We found that most of the cattle and sheep were directly raised in mixed herds without isolation or testing,and the risk of infectious diseases such as brucellosis was greater.It is suggested to further strengthen the transportation supervision of cattle and sheep,and strengthen publicity to reduce the risks of epidemics.
