Comparison of Anatomical and Blood Biochemical Parameters of Iranian Racing and Dual-Purpose Camels (Camelus dromedarius)

BACKGROUND: Animal breeds are often recognized through their specific characteristics, nevertheless, the breeds' anatomical and biochemical characteristics have not considered yet in many of the researches done on one-humped camels. There are some particular differences in camel breeds due to different climate conditions and rearing necessity. OBJECTIVES: The aim of the current study was to compare differences in anatomical and plasma biochem- ical parameters of two Iranian one-humped camels, the Jammaz (racing) and Balouchi (dual-purpose) breeds. METHODS: Anatomical parameters were body length (BL), neck length (NL), chest girth (CG), barrel girth (BG), hump circumference (HC), fore limb length (FLL), hind limb length (HLL), height at hump (HH), fore limbs interval (FLI), hind limbs interval (HLI), fore hoof circumference (FHC), hind hoof circumference (HHC), abdominal circumference (AC), shank circumference (SC) and leg circumference (LC). Moreover, concentra- tions of Glucose, blood urea nitrogen (BUN), creatinine, cholesterol, total bilirubin (Bili-T), direct bilirubin (Bi- li-D), calcium (Ca), phosphorus (P), magnesium (Mg), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), total protein (TP), albumin (Alb), triiodothyronine (T3) and thyroxine (T4) were measured as plasma biochemical parameters. Data analysis was conducted through t-test statistics. RESULTS: Results revealed significant differences between body type traits of breeds, especially in organs related to running ability, while the Jammaz breed has more height and longer limbs than the Balouchi breed. Some blood parameters (glucose, LDH, BUN, cortisol and T4) are considerably higher in Jammaz breed, too. CONCLUSIONS: Results of the current study suggest some anatomical (especially fore and hind limb lengths, neck length and body height at hump) and physiological characteristics (lactate dehydrogenase, blood urea nitrogen, cortisol, glucose and T4) of Iranian racing and dual purpose camels as breed markers.
