This study was conducted to investigate the effects of stress conditions in Single Comb White Leghorns(WL) and Korean Native Chickens(KNC) that were subjected to a high stocking density(311㎠/chicken) on the amount of telomeric DNA, the rate of DNA fragmentation, and the expression levels of HSPs and HMGCR genes. The telomere shortening rate of the lymphocytes was significantly higher in the stress group than the control. The DNA fragmentation also increased under stress conditions in both breed. The gene expressions of HSP90-α and HSP70 on blood and liver tissues were significantly higher in the stress group than the control, but that of HMGCR was not significant difference between stress and control group. The expressions of HSP90s and HSP70 in KNC were higher than those in WL. From the results of telomeric DNA quantity, total DNA fragmentation, and the expression level of the HSP90s and HSP70 gene, we concluded that the high stocking density was a distinctively stress source in chicken, regardless of breed. However, the effect of chicken breed on the stress response was not found.
