Abstract: 20 microsatellite primer sites recommended by FAO (food and agricultural organization) and ISAG (international society of animal genetics) were used to detect the genotypes of 83 individuals in conservation population of Dahe pig. The effect of conservation was analyzed and detected by calculating allele frequency, heterozygosity (H), polymorphism information content (PIC), the number of effective allele, and coefficient of inbreeding. The results showed that the genetic polymorphism of the Dahe pig, as a local breed of pig, in 20 microsatellite sites was affluent with 137 alleles averaging 6.85, 104 effective alleles averaging 5.2; the genetic diversity was abundant in Dahe pig. The heterozygosity was 0.792 and the PIC was 0.765.
