Effect of the administration of intraruminal selenium boluses in goat kids on biomarkers of oxidative stress in plasma
Abstract This study aimed to evaluate the effect of Se administered through intraruminal boluses in goat kids and correlate it with the levels of the mineral and the biomarkers of oxidative stress in the blood. Fifteen goat kids of 8 to 9 wk of age of the Alpine breed with an average weight of 13.7 kg were used and divided into three groups: Selenium group (a sodium selenite bolus was administered orally, with an equivalent content of 90 mg of Se); Se-SMZ group (a bolus of sodium selenite was administered orally, with a content equivalent to 90 mg of Se and 4 g of sulfamethazine a); Placebo group (a placebo bolus was administered orally). Plasma Se levels were carried out through the technique of atomic absorption spectrophotometry. The concentration of TBARS and GSH were estimated through spectrophotometry. The established significance was P<0.05. After the administration of the selenium and SE- SMZ Se boluses, the goat kids increased the levels of Se in plasma starting 3 h after dosing, with a significant difference (P<0.05) between the Se vs Se-SMZ until 3 and 24 h. The groups of bolus-dosed animals had variability in plasma TBARS levels without showing a constant trend (P>0.05). GSH levels did not show significant differences between the groups. In conclusion, the boluses with Selenium and Se-SMZ increased plasma Se levels. There was wide variability in plasma TBARS levels and GSH levels did not show relevant significant differences between treatments. Boluses were a good alternative to supplement Se to ruminants.
