Abstract:
Objective To analyze and evaluate the population genetic quality of 3 subbreeds of China Agricultural University miniature pigs in Beijing.Method According to the local standard DB11/T828.3 -2011, 25 pairs of microsatellite primers were used in 3 subbreeds of China Agricultural University miniature pigs, and software Popgen32 was used to process the data.Results 24 microsatellite loci shared 130, 122 and 138 alleles in the China Agricultural University miniature pigs I, II, III, respectively. The average heterozygosity was 0.6759, 0.5967 and 0.6779, respectively, while the average polymorphism information content ( PIC) was 0.6344, 0.5540 and 0.6403, respectively. The genetic distance between China Agricultural University miniature pig II and III was 0.4251, while the genetic distance between China Agricultural University miniature pig I and II was 0.2084.Conclusions In the 3 subbreeds, China Agricultural University miniature pigs II and III have genetic stability and genetic diversity, and both of which satisfy with the genetic characteristics of closed colony laboratory animal.
