Abstract: This study aimed to investigate the HSPs (60 and 70) expressions and physiological parameters of heatstressed. This study involved 65 Saanen and 73 Alpine crossbreds reared at the Dairy Goat Research Farm of Çukurova University, Adana (Turkey). Physiological parameters (rectal temperature, respiration and pulse rate) and climatic data (air temperature, relative humidity) were recorded. In addition, blood samples were collected from jugular vein to get the plasma samples which were used to assay the concentration of HSP 60 and 70. The environmental conditions reflected through a high THI (THI= 82.6) showed that the goats were subjected to thermal stress. On the other hand, the average HSP 60 significantly lower in winter (4.4 ± 0.5 ng ml) followed by spring (7.6 ± 0.6 ng ml) and summer (9.05±0.82 ng ml). Whilst, the HSP 70 was 22.6 ± 0.6, 14.4 ± 0.5 and 13.3 ± 0.4 ng ml in summer, spring and winter respectively. We can concluded that under harsh conditions the dairy goats synthesised more heat shock protein which can be used as thermoregulatory indicator.
