| Abstract: | 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?P?
