Abstract
The aim of this study was to determine concentrations of selenium in the liver and kidneys of roe deer and red deer from West Pomerania, depending on the season. Altogether, samples from 169 animals were collected (96 from roe deer and 73 from red deer) in 2003–2007. The mean concentration of selenium in the liver of red deer and roe deer was 0.37 μg/g and 0.62 μg/g dry weight, respectively. In kidneys, Se concentration was 2.72 μg/g d.w. in red deer and 2.99 μg/g d.w. in roe deer. In roe deer, liver selenium concentration in autumn was significantly higher than in winter (P < 0.05) and spring (P < 0.01) and significantly lower in spring than in summer (P < 0.05); likewise, kidney selenium concentration was higher in autumn than in summer. In deer, no statistically significant season-related differences were observed for liver selenium concentrations. In red deer kidneys, selenium concentration was the lowest in summer, significantly lower than in autumn and winter. Low selenium concentrations in the analyzed tissues show that the animals live in areas deficient in this element.
