| Popis: | This study evaluated the effect of selenium (Se, Se-yeast) and vitamin E (E, DL-α-tocopherol) supplementation on erythrocyte superoxide dismutase activity (SOD) and blood concentrations of zinc (Zn) and copper (Cu) in moderately exercised horses. Veterinary Medicine School of National University of Mexico approved experimental procedures. Twenty-four healthy police horses (5–15 yr, 450kg BW), without exercising the month prior to this trial, were individually stabled, randomly allocated in a factorial experiment (2Se �-2E levels) with repeated measures. Experimental groups (n=6) were: LSeLE, HSeLE, LSeHE and HSeHE (LSe, 0.1; HSe, 0.3 mg Se/kg DM and LE, 1.6; HE, 2 IU E/kg BW; NRC, 2007). Daily ration was poor in antioxidants (Se, day. SOD and Zn-Cu were quantified using spectrophotometry and atomic absorption spectrometry, respectively. Data were analyzed by a mixed model (PROC MIXED, SAS 9.1.3) with the design described above. Day, Se, E and their interactions were the fixed effects, while horse nested within treatment was the random effect. Significance was set at Pvs 44.5U/mL±4.84 SE; 5.2 vs 2.2µg/mL±0.1 SE, respectively). Cu was higher in d7 and d77, than in d33-d56 (Pvs 1.28μg/mL±0.05 SE, respectively). Conclusion: SOD, Zn and Cu were not affected by supplementation levels of both Se and E; however, they were strongly modified by physical activity. |
