Abstract
The correct concentrations of biological elements allow biochemical processes to proceed normally, and thus enable the proper functioning of the organism. The aim of the study was to determine characteristics of the mineral metabolism of horses raised in a region characterized by mineral deficiencies as a basis for evaluating their diet. Ten horses were selected for the study (5 mares and 5 geldings), all kept in similar conditions. The horses were used for recreation and sport. The study was conducted in two periods: after the pasture season (end of November 2015) and at the beginning of the pasture season (end of May 2016). Blood was collected from the jugular vein into sterile test tubes without coagulant. The evaluation of the concentrations of copper and zinc in the blood serum of the horses revealed substantial deviations from physiological norms. The serum concentrations of Cu and Zn were below the lower reference levels. On the basis of the study it is difficult to conclusively state which factor is decisive in determining the content of calcium, zinc and copper in the serum of horses over the course of the year. It seems likely that the serum concentrations of these elements may be determined by their content in the horses’ feed. Therefore it would be advisable to supplement the supply of copper and zinc in the feed ration in both the summer and winter seasons. Moreover, further research should be conducted in the region to determine the supply of copper and zinc to horses.
