Abstract: Thermal shock is expressed through the response of high levels of a thermal shock protein (tolerant gene expression).in this way, the cell gets rid of heat. The current study aims to assess the relation between the concentration of heat shock protein and dairy performances in goats under hot environment. the study performed at dairy goat research farm of Cukurova University. Located in the province of Adana. Milk yields were weekly recorded. The average ambient temperature between 28.7 and 34.9C, THI were higher than 78. HSP60 and HSP70 were 4.4 and 8.7ng/ml, and 13.9 and 18.34ng/ml for Alpine and Saanen goats respectively. The cellular thermoregulatory response directly expressed by an increasing activation and format of HSP60 and HSP70 was demonstrated to be negatively correlated to lactation performances in the thermal stressed goats.
