title: Heavy metal concentration in coat hair and hoof horn in stabled and reserve Polish Konik horses.
abstract: The objective of the study was to determine if there were differences in Cr, Mn, Cu, Cd, Pb and Ni levels in coat hair and hoof horn between Polish Konik horses maintained in stabled and reserve systems in Roztocze National Park in Poland. Summer and winter feeding seasons (seasons of the year in case of hooves) and age of horses were taken into account. 107 samples of hair and hooves, as well as all kinds of feed and sources of water available for the horses were examined. The results of the study indicate that the concentration of the elements in the coat hair, hoof horn, feeds and water is usually too low to show possible influence of the system of maintenance in feeding seasons and age effect. The reserve horses are not more exposed to heavy metal contamination than the stabled horses. In the hair, solely Mn level is affected by the systems of maintenance in summer and winter feeding seasons: during winter it is higher, particularly in the stabled system, than during summer. In hooves, Cr concentration is higher in stabled horses than in reserve horses and conversely, Cu content is higher in the reserve horses. Mn content is age-affected both in hair and hooves, likewise is Cu content in the hooves. The results indicate a necessity of Cu compound supplementation in feeding the horses in both systems of maintenance.
