The invention discloses a high-flux micro-fluidic chip for detecting pathogeny of the epidemic disease of the respiratory tract of pigs and a detection method and belongs to the technical field of biological chips. The high-flux micro-fluidic chip comprises an LAMP amplification reagent, a DNA/cDNA template, ddH2O, LAMP positive control, LAMP negative control, a detection chip, a chip probe and amicro-fluidic chip analyzer, the detection chip is placed in the constant-temperature amplification micro-fluidic chip analyzer, and the chip probe comprises nucleotide sequences shown in SEQ ID NO:1-42 and specific nucleic acid segments applied to detection of the hog cholera virus, porcine reproductive and respiratory syndrome virus, porcine circovirus 2 type, porcine circovirus 3 type, haemophilus parasuis, mycoplasma hyopneumoniae, porcine pasteurella and swine influenza virus. According to the high-flux micro-fluidic chip, detection can be completed within one hour, the detection limit is5*10-2ng/microliter, different kinds of pathogeny of the epidemic disease are accurately distinguished, and the high-flux micro-fluidic chip has the advantages of quick detection, high sensitivity and accurate specificity.
