| Abstract | ||||
| The cicadian rhythm of biomarkers of bone formation including osteocalcin and bone alkaline phosphatase (BAP) was studied in the serum of dromedary camels. Blood samples were collected every 60 minutes for 24 hour from 10 healthy adult female camels. ELISA was used to determine the concentrations of serum osteocalcin and BAP. The results showed a marked fluctuation in the concentration of oteoclacin during 24 hour period with minimum ad maximum levels at 13:00 (01:00 pm) and 1800 (06:00 pm), respectively. Slight fluctuation was observed in the concentration of BAP with minimum and maximum levels at 1:00 am and 12:00 pm, respectively. The correlation between the two biomarkers was weak. It was concluded that it is important to fix the time of blood sampling for analysis of osteocalcin concentrations, but not for BAP. | ||||
