“…The latter found that Zn concentration in camel liver was not different from that in sheep, goats, and cattle. Hepatic iron level in normal camels ranged between 260 and 280 ppm as reported by Abu Damir et al [ 14 ], Awad and Berschneider [ 13 ], and Wensvoort [ 15 ] but Bakhiet et al [ 12 ] reported 560 ± 38 ppm. Low hepatic manganese values as for other ruminants were reported in the camel; these values ranged between 2 and 10 ppm [ 11 , 13 ].…”

One hundred camels (Camelus dromedaries) and fifty sheep and goats being adult, male, and apparently healthy field animals were studied to provide data regarding the normal values of some hepatic trace elements. Liver samples were collected during postmortem examination, digested, and analyzed for Cu, Zn, Fe, Co, and Mn using atomic absorption spectrophotometry. The results showed that the differences in mean liver concentrations of Cu, Zn, Fe, and Co between camels, sheep, and goats were statistically significant (P < 0.05). Hepatic Cu, Fe, and Co concentrations were higher in camels than in sheep and goats. All liver samples were adequate for Fe and Co, whereas only camel liver was adequate for Cu. In camels, hepatic Zn concentration was inadequately lower than that in sheep and goats. No difference in Mn concentration was detected between camels, sheep, and goats. All liver samples were inadequate compared to free-ranging herbivores. In camels, significant correlation (r 2 = −0.207, P value = 0.04) was detected between Zn and Co, whereas in sheep significant correlation (r 2 = −0.444, P value = 0.026) was detected between Zn and Mn. No significant correlation between trace elements was detected in goats.

“…Copper toxicity in natural conditions was not reported, but experimental intoxication was achieved by Abu Damir et al [ 104 ], provoking anoxia, the regurgitation of the gut contents, teeth gnashing, diarrhea and the lateral decubitus position before death within 8 days of injecting 200 mg copper.…”

Trace minerals play an important role in animal health and productivity. They are involved also in many physiological activities, and their deficiency causes a variety of pathological problems and metabolic defects, reducing consequently the animal productivity. The demand for animal products in semi-arid areas is rapidly increasing, and the supply is still below the required level, partially due to low animal productivity. Camels (Camelus dromedarius and Camelus bactrianus) are considered one of the main sources of healthy, high-quality meat and milk for human consumption within most of the countries in the semi-arid regions. Despite their efficient adaptation to their environment, camels can suffer from the growth retardation of newborns, low feed efficiency, anemia, poor fertility, poor reproduction and many other metabolic disorders. It is well known that trace mineral deficiencies and trace mineral toxicities can influence camels’ production and reproductive efficiency, as well as many aspects of their growth and metabolism. Evaluating the trace minerals status of camels and their variability is an obvious step toward improving camels’ productivity and health. Thus, the present article reviews the data regarding the status of trace minerals (copper, zinc, iron, selenium, manganese, cobalt, iodine, fluorine, molybdenum, sulfur, bromide and nickel) in camel blood and their physiological variability, with a focus on their deficiency and toxicity effects.

“…This proves that cupric oxide needle capsules are lodged in the camel forestomach and released slowly to the blood. The cupric oxide dose used in this study is safe as none of the experimental animals showed sign of neither copper toxicity nor displayed sharp rise with toxic copper levels in serum (Abu Damir et al 1993). i.e., the maximum serum copper attained (16.6 μmol/L) was in week four by a single animal (Fig.…”

Copper was determined in the blood of breeding camels, camel calves and racing camels to evaluate copper status in these animals in UAE. Low blood copper concentrations were reported in newly born camel calves (100%) and calves 2-4 months old (68%), breeding camels at early (55.6%) and at mid lactation (48%) and at late pregnancy (69%). This is attributed to the low copper and high sulfate in the Rhodes grass which is the only diet offered to the breeding camels. On the other hand only 9.7% of racing camels showed low copper levels. This is because copper is routinely offered to racing camels when their blood copper is low. Cupric oxide needle capsules orally administered at the rate of 8 g per adult camel was effective in elevating blood copper from 7.083 micromol/L at day zero to 10.074 micromol/L at day 28 after dosing.
