Turkey is a country with mild climate where four seasons coexist due to its geographical location. Daily average
temperature values in summer months (June, July, August, September) can exceed 25 °C. All living organisms can be exposed
to heat stress, especially in the Mediterranean and Aegean regions where the humidity and in Southeastern Anatolian Regions
where temperature is very high. When assessed for animal production, heat stress can cause significant yield losses in dairy
cattle grown in these regions. While some criteria are used to determine and evaluate heat stress, the most commonly used
parameter is temperature-humidity index (THI) value. Data obtained from the Siirt meteorology department and from the
meteorological stations in the districts were used to determine the temperature humidity index values for Siirt provinces and
districts. According to this, temperature humidity index values of Siirt Merkez, Pervari, Baykan, Kurtalan, Şirvan and Eruh
districts were 72.43, 67.64, 71.80, 72.34, 71.67 and 68.87, respectively. In the study, the temperature-humidity index values
of Siirt province and its districts exceeded 65 or 72 threshold values in June, July, August, and September. However, in terms
of heat stress, it is understood that Pervari and Eruh districts are statistically (p<0.05) more suitable for dairy cattle farming
than other districts. As a result, in Siirt conditions, adequate cooling systems must be used at times when heat stress occurs
for a sustainable dairy cattle farming.
