Abstract: To provide the technical support for the cultivation of "strain of specialization with anti-stress and sensitive gene" of Guizhou local pig genes, the RYR1 gene in 151 samples from 5 local pig species of Baixi, Qianbei Black, Zongdi Hua, Nuogu, Congjiang Xiang and three-crossbred commercial pig were detected by PCR-RFLP technique. The pigs with HalNn of recessive anti-stress and sensitive genotype, HalNN of anti-stress and sensitive genotype and Halnn of stress and sensitive genotype were screened out. The results showed that all of 5 Guizhou indigenous pigs belonged to HalNN , there was no Halnn gene in the three-crossbred pigs, HalNn accounted for 52.63 % of the samples, and Haln allele frequency was 26.32%.
