The present study was conducted to ascertain the adaptive capability of pigs to different seasons based on changes in serum cortisol and lactate dehydrogenase (LDH) levels, and peripheral blood mononuclear cell (PBMC) heat shock protein 70 (HSP70) mRNA expression. Based on average THI, the seasons were classified as winter (November–February), spring (March–June), and summer (July–October). Hormone cortisol was found to be influenced by season (p < 0.01), age (p < 0.05), and genetics of the animal (p < 0.05). However, level of LDH was not influenced by either of these factors. HSP70 mRNA expression was higher in almost all age groups in crossbred and exotic pigs during summer in comparison to other seasons. Lower HSP70 gene expression was observed in almost all age groups of native pigs in comparison to crossbred and exotic during summer. In conclusion, native pigs were acclimatized for thermal stress in comparison to crossbred and exotic breeds of pigs. Also, the expression pattern of HSP70 gene is breed-specific, most likely due to variations in thermal tolerance and adaptation to different environmental conditions. Both serum cortisol and HSP70 gene may act as reliable biological markers for assessing the adaptive capabilities of pigs to different seasons.
