“…However, the resulting correlation obtained in previous reports using blood selenium concentration was higher (r = 0.935) [6,9]. These findings are in agreement with those reported by Maas et al [14], whom, by using dairy cattle as the species under study, suggested that blood selenium concentration is a better status indicator than serum selenium.…”

“…However, our mean values were higher than previously reported in the dromedary camels used just for the GSH-Px/blood selenium correlation [6,9], probably due to the wide standard deviation that is shown in the GSHPx activity in several species [1,16,17].…”

“…In the dromedary camel, a high correlation between GSH-Px activity and blood selenium has previously been reported [6,9]. However, the number of animals investigated in these studies (20 and 53, respectively), considered sufficient to determine this correlation, seems to be inadequate for a population study of GSH-Px activity in the dromedaries, particularly due to large standard deviation described in many species [1,16,17].…”

-Blood glutathione peroxidase (GSH-Px) levels in 709 normal dromedary camels (442 females and 267 males) were assessed in the Canary Islands. All animals were intensively reared, and three different nutritional systems were evaluated, depending on selenium content of the diet. Mean GSH-Px level in the total population was 288.5 ± 157.2 IU⋅g -1 Hb. Reference ranges were estimated and enzymatic activities below 51 IU⋅g -1 Hb were considered inadequate. GSH-Px activities obtained in females (298.1 ± 155.7 IU⋅g -1 Hb) were significantly (P = 0.037) higher than in males (272.6 ± 157.2 IU⋅g -1 Hb). When age groups were compared, only males between 6 and 12 months old exhibited significantly lower mean GSH-Px (P = 0.006) than females. A high correlation (r = 0.88) between serum selenium concentration and blood GSH-Px activity was estimated, and the regression equation was y = 2.5101x + 42.423. Selenium content of the diet above 0.1 mg⋅kg -1 DM seems to supply adequate selenium requirements for dromedaries under intensive husbandry. dromedary / camel / nutritional myodegeneration / glutathione peroxidase / seleniumRésumé -Détermination des niveaux sanguins de glutathion péroxydase chez le dromadaire. Les niveaux de glutathion péroxydase (GSH-Px) dans le sang de 709 dromadaires sains (442 femelles et 267 mâles) ont été mesurés dans les Îles Canaries. Tous les animaux ont reçu un élevage intensif et trois systèmes de nutrition ont été évalués en fonction du contenu en sélenium de l'alimentation. L'activité moyenne de GSH-Px dans l'ensemble de la population a été évaluée à 288,5 ± 157,2 IU⋅g -1 Hb. Les intervalles de référence ont été estimés et les activités enzymatiques en dessous de 51 IU⋅g -1 Hb ont été considérées insuffisantes. Les activités GSH-Px obtenues chez les femelles (298,1 ± 155,7 IU⋅g -1 Hb) étaient significativement (P = 0,037) plus élevées que chez les mâles (272,6 ± 157,2 IU⋅g -1 Hb). Quand les groupes d'âge ont été comparés, seuls les mâles âgés de 6 à 12 mois montrèrent une valeur moyenne de GSH-Px significativement (P = 0,006) plus basse que les Vet. Res. 32 (2001) 185-191 185

“…Selenodeficiency is a common fact in UAE, where cases of degenerative myocarditis are regularly observed on young camel [7,8]. Other cases of selenium deficiency on camel were reported in Canary Islands [9], Saudi Arabia [10], Morocco [11], China [12], Sudan [13], or in zoological parks [14], but no case of selenium intoxication was described. In order to prevent such diseases, commercial concentrates (pellets including soya bean meal, maize, barley, wheat bran, molasses, salt, and premix) used for camels were regularly supplemented with selenium salt and vitamin E, generally mixed in a mineral supplement or a pre-mixture.…”

Eight young female camels shared in four groups of two 2 years received a basal diet enriched respectively with 0, 2, 4, and 8 mg selenium under sodium selenite form for 64 days. Feed intake was assessed daily; blood samples were taken on weekly basis. One camel from each group was killed at the end of the experiment. Se concentration in serum was increased significantly in the supplemented groups with an average of 176.3 +/- 18.0 ng/mL in the control group, 382.7 +/- 107.6 in the group receiving 2 mg Se, 519.8 +/- 168.4 in the group receiving 4 mg Se, and 533.4 +/- 158.6 in the group receiving 8 mg Se daily. For glutathione peroxidase (GSH-Px) activity, the control group (51.0 IU/g Hb) and the group receiving 2 mg (50.5 IU/g Hb) were significantly different than groups receiving 4 and 8 mg (respectively, 65.9 and 76.1 IU/g Hb). No significant variation occurred for vitamin E (mean, 0.56 +/- 0.23 ng/mL). Significant correlation between serum Se and GSH-Px was reported. Kidney was the richest organ in selenium followed by lung, spleen, and liver, but the increase in supplemented groups was more marked in liver and kidney. The hair seemed to be the best indicator of selenium intake in camel.

“…Selenium concentration in blood serum and tissues According to previous studies, 100 ng/mL Se concentrations in blood serum of camels consider being within the normal level for proper metabolic functions as reported for other ruminant animals (Maas et al, 1990;Hamliri et al, 1990;Barri and Sultan, 2007;Shen and Lia, 2010). Researchers from different countries reported lower or higher Se levels, range between 12 to 200 ng/mL, which can be resulted from the different dietary Se intake, sex, age, breed, physiological status and many other factors that not well documented.…”

Selenium (Se) and iodine (I) are very important trace mineral for animals and human health. Selenium is an essential constituent of the antioxidant enzyme GSH-Px, while I as a thyroid hormone play a crucial role in regulating body metabolism. The aim of this study was to provide preliminary data on the Se and I status of two camel breeds (Majaheem and Maghateer: Camelus dromedaries) raised under the semi intensive system in Saudi Arabia (SA). Ten Majaheem male camels and ten maghateer, age 1.5±0.5 yrs old, were slaughtered and blood and tissues (liver, kidney and meat) were collected. Blood serum samples were analyzed for Se, thyroxine (T4), triiodothyronine (T3), glucose, cholesterol, true protein and albumin. Tissues samples were wet digested and analyzed for Se level using Atomic Absorption Spectrophotometer. Results showed a significant breed effect on serum and tissues Se with higher concentration of Majaheem compared with Maghateer breed. The same trend was found for glucose and total protein. In conclusion, a highly significant breed effect was reported for Se metabolism. The highest Se concentration occurs in kidney followed by liver and meat.
