Abstract:In this study, a quick method to identify ingredients of chicken origin in livestock and poultry meat was developed by polymerase chain reaction (PCR) and fluorescence quantitative PCR using mitochondrial DNA cytochrome C coxidase subunit Ⅰ (CO Ⅰ ) gene as target gene. The mitochondrial DNA CO Ⅰ genes from chicken, duck, goose, pig, cattle, sheep, rabbit, pigeon and quail revealed distinct loci. Based on this, a set of chicken-specific primers was designed. The results showed that the designed primers could only amplify template DNA from chicken with a cycle threshold (Ct) value of 21.78. The PCR assay had a high specificity and sensitivity (at pg level) and it could be used to detect ingredients of chicken origin in livestock and poultry meat quickly and accurately.
