Improve the detection ability of theoretical knowledge. According to Baijiahao, the training characteristic of veterinary laboratory after training is to improve the detection ability of theoretical knowledge. The experts taught in this training are all experts with certain influence in Hubei animal epidemic control system. With profound theory and rich practical experience, the laboratory taught the key points of experimental detection techniques such as ELISA antibody monitoring of brucellosis, fluorescent PCR detection of African swine fever and hemagglutination test of avian influenza. Through study, we have accumulated rich theoretical knowledge and further improved the skills of animal epidemic detection, so training is necessary.
