Roe deer (), as a representative of the Cervidae family, are particularly sensitive to negative environmental stimuli due to their need to maintain increased vigilance during feeding. Intensive hunting seasons are undoubtedly also a stressful factor for this species. The aim of this study was to analyze the cortisol levels in the hair of male roe deer collected at the beginning and the end of the hunting season in eastern Poland. In total, hair samples from 26 individuals collected in May and 31 individuals collected in September were analyzed. The concentration of cortisol in the hair was determined using the EIA kit. It was shown that the concentration of cortisol was significantly higher in samples collected in September compared to those collected in May (Pr. > |t| = 0.0017). Moreover, the age of animals and carcass mass did not significantly affect the concentration of the tested hormone. In summary, the concentration of cortisol in the fur of male roe deer depended on the season and was not influenced by the carcass mass or age of the animals studied.
狍作为鹿科动物的代表，由于其在觅食时需要保持更高的警惕性，所以对负面环境刺激特别敏感。密集的狩猎季节无疑也是该物种面临的一个压力因素。本研究的目的是分析在波兰东部狩猎季节开始和结束时采集的雄性狍毛发中的皮质醇水平。总共分析了5月份采集的26个个体和9月份采集的31个个体的毛发样本。使用酶免疫分析试剂盒测定毛发中皮质醇的浓度。结果表明，与5月份采集的样本相比，9月份采集的样本中皮质醇浓度显著更高（Pr. > |t| = 0.0017）。此外，动物的年龄和胴体质量对所测激素的浓度没有显著影响。总之，雄性狍皮毛中皮质醇的浓度取决于季节，不受所研究动物的胴体质量或年龄的影响。
