摘要： Min Pig (Sus scrofa) is a northern Chinese domestic pig breed, whose cold resistance is remarkable. However, the cold-resistant phenotype of Min Pig is unclear. Our studies showed that in long-term cold exposure, the death rate of Min Pigs is significantly lower than that of the control Large White (LW) Pigs. The ear tissue freezing rate for Min Pigs is 0%, but that for LW Pigs is 100%. The shivering time and shivering frequency of Min Pigs are both significantly lower than that of LW Pigs at 5 months (P<.005) and in 80-90kg pigs (P<.001). Our results indicated that Min Pig is more cold resistant than LW Pig in long-term cold exposure. These findings provided important reference data for the field of cold resistance research in Min Pigs, and for the breeding of cold-resistant pigs.
