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.||URI:||http://hdl.handle.net/10553/47941||ISSN:||0928-4249||DOI:||10.1051/vetres:2001119||Source:||Veterinary Research[ISSN 0928-4249],v. 32, p. 185-191|
