In order to evaluate the sera concentrations of iron, copper, zinc and manganese trace minerals in thirty Pure-bred Lusitano athlete horses before and after exercise certified by clinical and laboratory assessments were studied. Blood samples were taken before and after 20 minutes of a dairy trot and gallop slight training, perfomed in a sandy floor ring, to measure the mineral concentrations, by atomic absorption spectrophotometry. It was observed that after exercising, the serum activity of iron did not change (P=0.2365), whereas copper values have significantly risen after training (P<0.001). On the other hand, zinc and manganese trace minerals decreased after exercise (P<0.001). In conclusion, it is possible to consider that the short time exercise may trigger sweating and consequently to change the serum concentration of iron, cooper, zinc and manganese in Pure-bred Lusitano athlete horses. |
