Abstract :

This research was carried out to compare the physiological responses between exotic and local bucks to reveal their adoptation to the Mediterranean region of Turkey. The effect of seasonal variation on rectal temperature (RT), respiration rate (RR), heart rate (HR) and some blood parameters were evaluated in Saanen (S), Hair (H), German Fawn x Hair (GF) and Damascus x Hair (DM) bucks. Blood parameters and physiological responses of bucks were measured three times in a day for one week periods in May, July and December. The mean heart rate of Saanen (121 beats/min) was higher than Hair bucks (113 beats/min). Heat stress generally decreased the blood glucose levels and reached the highest levels in the mornings in December. Blood glucose concentrations were highest for H bucks (63.8 mg/dl) and lowest in S (34.7 mg/dl) in December. Total serum cholesterol (CHO) levels were found to be similar to blood glucose levels but increased mostly in S and H bucks when the environmental temperature decreased.Given the blood parameters and physiological responses, it was determined that there were some differences related toblood and physiological parameters between local and exotic breeds. In addition, exotic breeds may adapt to theMediterranean climate conditions and can be recommended by virtue of their improved performances.
