“…This proportion is similar to the proportions previously found in sheep and horses (Piccione et al, 2005). The mean level of the measured variables was generally within the range of values reported in previous studies in camels (Aichouni et al, 2010;Ayoub and Saleh, 1998;Bekele et a., 2013;Eltahir et al, 2010;Hussein et al, 1992) with, notably, lower plasma concentrations of sodium, creatinine, ALP, ALT, AST, and LDH but higher concentrations of cholesterol, globulin, and total protein in our study.…”

Abstract Camels are well adapted to hot arid environments and can contribute significantly to the economy of developing countries in arid regions of the world. Full understanding of the physiology of camels requires understanding of the internal temporal order of the body, as reflected in daily or circadian rhythms. In the current study, we investigated the daily rhythmicity of 20 physiological variables in camels exposed to natural oscillations of ambient temperature in a desert environment and compared the daily temporal courses of the variables. We also studied the rhythm of core body temperature under experimental conditions with constant ambient temperature in the presence and absence of a light-dark cycle. The obtained results indicated that different physiological variables exhibit different degrees of daily rhythmicity and reach their daily peaks at different times of the day, starting with plasma cholesterol, which peaks 24 minutes after midnight, and ending with plasma calcium, which peaks 3 hours before midnight.Furthermore, the rhythm of core body temperature persisted in the absence of environmental rhythmicity, thus confirming its endogenous nature. The observed delay in the acrophase of core body temperature rhythm under constant conditions suggests that the circadian period is longer than 24 hours. Further studies with more refined experimental manipulation of different variables are needed to fully elucidate the causal network of circadian rhythms in dromedary camels.

“…The difference in semen parameters (decreased motility and concentration, and increased abnormalities) was associated with an increase in Fe, Zn and Cu levels in the seminal plasma, and Fe and Zn levels in the serum, of infertile camels. In the current study, serum concentrations of Fe, Zn and Cu in the control camels were higher than the concentrations recorded in the serum of male (2.131, 0.243 and 0.567 mg/L, respectively; Faye, Seboussi, & Askar, ) and blood plasma of female (1.198, 1.068 and 0.755 mg/L, respectively; Eltahir, Ali, Mansour, & Mahgoub, ) camels. Seminal plasma and blood concentrations of Zn and Cu are not dissimilar between subfertile and fertile men (Wong et al, ).…”

A total of 14 camels of known fertility (controls) at the Camel Research Centre, King Faisal University and 41 infertile dromedaries brought to the Veterinary Teaching Hospital were used in this study during the breeding season. Seminal plasma and serum were obtained from all males, and stored at -80°C until analysis. Concentrations of six trace elements (manganese [Mn], zinc [Zn], iron [Fe], selenium [Se], copper [Cu] and chromium [Cr]) were estimated in the seminal plasma and serum using an atomic absorption spectrophotometer. Results showed significant (p < 0.05 and p < 0.01) differences in semen pH and sperm motility, concentration and abnormalities between the control and infertile dromedaries. In seminal plasma, a significant (p < 0.01) difference in Fe concentrations (7.792 ± 1.567 vs. 61.259 ± 11.967 mg/L) and significant (p < 0.05) differences in Zn (24.763 ± 8.206 vs. 83.981 ± 4.972 mg/L) and Cu (1.653 ± 0.348 vs. 7.905 ± 1.134 mg/L) concentrations existed between the control and infertile dromedaries, respectively. In serum, there were significant (p < 0.05) differences in Fe (6.237 ± 0.695 vs. 151.121 ± 27.604 mg/L) and Cu (24.703 ± 4.195 vs. 6.375 ± 0.644 mg/L) concentrations and a significant (p < 0.01) difference in Zn concentrations (17.086 ± 1.606 vs. 90.422 ± 4.347 mg/L) between the fertile and infertile camels, respectively. There were significant (p < 0.05) positive (r = 0.51) and negative (r = -0.54) correlations between Zn concentrations in seminal plasma and both sperm motility and sperm abnormalities, respectively. In conclusion, seminal plasma and serum trace elements of Fe, Zn and Cu influenced the semen parameters and fertility of dromedary camels. Low concentrations of Fe, Zn and Cu in the seminal plasma were associated with normal fertility in dromedaries.

“…This was similar to reports in Omani racing camels (Eltahir et al, 2010). Although there are not many reports on this aspect, Kuria et al (2006) reported a significant positive correlation between Na and Ca but a negative correlation between Na and P. On the contrary there were no significant correlations within trace elements but there was a significant correlation between Cl and Ca, K and Na (Table 4).…”

Blood samples were collected from thirty, 2-year old female Arabian camels from the eastern region of Oman. Camels were managed in the traditional way in the Arabian Gulf region, primarily fed fresh alfalfa and barley grain. Blood was drawn into serum vaccutainers from jugular venipuncture. Serum samples were analyzed by spectrophotometric analysis using a CX7/CX7 serum chemistry analyzer (Synchron, Beckman). Means, standard deviations and minimum and maximum values were calculated using Excel spreadsheets on Microsoft Office 2007. The SAS (2000) package was used to produce coefficient of determination (R2) between the eight serum mineral values. The following mean values Å} standard deviation were recorded: glucose: 92.8Å}19.2 mg/dL; total protein (TP): 6.17 Å} 0.34 g/dL; albumin: 32.21 Å} 9.933 mg/dL; blood urea nitrogen (BUN): 15.48 Å} 4.49 mg/dL; creatinine: 1.64 Å} 0.238 mg/dL; uric acid: 0.28 Å} 0.041 mg/dL; total globulins (TG): 0.28 Å} 0.041 mg/dL; cholesterol: 40.52 Å} 13.225 mg/dL; total bilirubin: 0.34Å}0.124 mg/dL; alkaline phosphatase (ALP): 113.9Å}29.75 (IU/L); aspartate aminotransferase (AST): 88.8Å}70.03 (IU/L); alanine aminotransferase (ALT): 13.3Å}5.97 (IU/L); Gamma-Glutamyl Transpeptidase (GGT): 21.3Å}10.18 (IU/L); lactate dehydrogenase (LD); 419.9Å}160.38 (IU/L); Creatine kinase (CK): 46.3Å}16.2 (IU/L); sodium (Na): 144.5Å}5.80 mmol/L; potassium (K): 4.23Å}0.42 mmol/L; calcium (Ca): 9.63Å}0.43; phosphorus (P): 9.56?Å}0.76 mg/dL; iron (Fe): 107.8Å}25.54 μg/dl; copper (Cu): 72.5Å}8.08 μg/dl; chlorine (Cl): 113.0Å}4.52 mmol/L. Findings of the current study provide baseline values that may be used by clinicians for racing camels in Oman. There were some significant correlations especially between macro minerals (Na, Ca, K, and P) that may be used to estimate their values with less cost by reducing the number of elements to be analyzed.
