| Resumo: |
The influence of chromium supplementation on some blood variables in 11 adult stallions used for policing activities was evaluated. Each animal was treated with 11mg of chromium/400kg body weight, orally, for a period of 30 days. On days 0 (before) and 30 (after) the animals were evaluated and blood samples were obtained before and after exercise. Plasma glucose and lactate and serum cortisol and insulin were analyzed in each of these moments. On day 0, plasma glucose concentrations were 68.4±5.6mg/dL and 78.7±6.5mg/dL; plasma lactate concentrations were 6.2±0.6mg/dL and 13.1±7.6mg/dL; serum cortisol values were 48.5±7.9ng/mL and 42.6±19.7ng/mL; and serum insulin values were 3.0±6.4µUI/mL and 1.9±1.7µUI/mL, respectively, before and after exercise. On day 30, plasma glucose concentrations were 73.3±5.7mg/dL and 78.4±6.7mg/dL; plasma lactate concentrations were 7.3±0.9mg/dL and 7.6±1.2mg/dL; serum cortisol values were 62.9±21.8ng/mL and 40.3±17.0ng/mL; and serum insulin values were 1.4±1.3µUI/mL and 1.7±1.4µUI/mL, respectively, before and after exercise. As an effect of the exercise, a decrease was shown in the concentration of serum insulin and an increase in plasma lactate and glucose. Chromium supplementation resulted in a reduction of lactate values after physical activity, possibly indicating that chromium contributed to a better utilization of plasma glucose and to a better adaptation of animals to physical activity.
