Abstract: The polymorphisms of the 2,4-dienoyl CoA redutase 1 (DECR1) gene in exon 2 site was detected using PCR-SSCP in 490 pigs of 5 pig breeds including Shanxi Mashen, Shanxi White, Landrace, Yorkshire and Duroc. The results showed that there was a polymorphism in the exon 2 site and three genotypes (AA, BB and AB) were found. Analysis of population genetics suggested that the frequency of B allele was dominant among the studied breeds. The results of Hardy-Weinberg equilibrium test indicated that Shanxi White and Duroc reached the equilibrium. All of the breeds had intermediate polymorphism information contents.
