The polymorphism distributions of 14 microsatellite loci were detected using the Bovine Paternity PCR Typing Kit (including 11 X-STR) and 3 selected Y-STR microsatellite DNA markers. The genetic diversity were evaluated, and the feasibility of the application to individual identification and paternity testing were discussed. The results showed that all the 14 microsatellite loci had genetic polymorphisms in bulls, and the polymorphism information content (PIC) in loci MCM158 was the biggest (0.888), while the ETH10 was the lowest (0.482). Power of discrimination (DP) value of the 14 STR loci ranged from 0.715 to 0.968. The Cumulate DP (CDP) was 99.99%, and the Cumulate PE (CPE) also reached 99.99%. These results indicate that the 14 microsatellites can be applied to the individual identification.
