Studies on the physiological responses related to seasonal variation in Çukurova Saanen and Balcali goats under sub-tropical climate conditions

This research was conducted in order to determine the physiological adaptation parameters related to the heat stress response of Çukurova Saanen (Saanen x Hair goat ) and Balcalı (German Fawn x Hair goat) goats under Çukurova Sub-tropical climate conditions. Regarding to the research three times a day (08.00-09.00, 12.00-13.00,16.00-17.00) during one week in February, April and June rectal temperature (ºC), Respiration rate (beat/min), Heart Rate (beat/min) were measured on the goats. Live weight changes of the animals are also determined through the experimental period.According to the results rectal temperature in February, April and June in Cukurova Saanen goats were 39.52ºC, 39.72ºC, 40.02ºC and in Balcali 39.6 ºC, 40.0 ºC ve 40.0 ºC, respectively Heart rate in February, April and June in Cukurova Saanen goats were 69.84, 72.64, 80.86 beat/min and in Balcali goats 69.10, 72.54, 79.32beat/min and respiration rate in Cukurova Saanen 42.76, 49.82, 54.32 beat/min and Balcali 40.54, 52.88, 51.77, respectively. Balcalı group responded with more advantage via the findings of heart rate under heat conditions. Again Balcalı group were advantageous with lower respiration rate overall.As a result, Balcali genotype has been found more resistant to the heat stress in terms of physiological adaptation parameters than Cukurova Saanen goats.
