Abstract:In order to establish a fluorogenic quantitative PCR method， which could identify the components of pig origin， specific genes sequences of pig was used as target sites， and the specific primers were designed. The DNA of common livestock and poultry meat including mutton， pork， rabbit meat， beef， pigeon meat， quail meat， chicken， duck and goose were used as template. And the template was diluted in eight gradients， for de－ tecting the sensitivity. The results showed that the established method could detect the pig origin effectively， which had a quite specificity and high sensitivity. The method could detect the pig origin in livestock and poultry meat quickly and accurately.
