The invention relates to the technical field of biology, and provides a recombinant protein and a preparation method and application thereof in bovine tuberculosis detection, the amino acid sequence of the recombinant protein is as shown in SEQ ID NO.1, and the nucleotide sequence of a gene for coding the recombinant protein is as shown in SEQ ID NO.2. The recombinant protein is obtained by serially connecting and combining the ESAT-6, the CFP-10 and the BFH by using a Linker according to a mode of the ESAT-6-CFP-10-BFH. According to the technical scheme, the problem that the sensitivity is low when an EC method is used for detecting bovine tuberculosis in the prior art is solved.
