The purpose of the study was to evaluate seasonal changes in selected trace elements such as Fe, Cu, Mn, Zn, and Al in the coat of healthy Hucul horses kept in south-eastern Poland in two different facilities and fed with locally sourced feed. The coat for the study was collected from 24 individuals in autumn, winter, and spring. The concentration of elements in the feed was also determined. The date of collection had a significant effect on the concentration of the micronutrients analysed in the coat of Hucul horses. The highest concentration of Zn was found in the coat taken in summer. The coat taken in autumn had the highest concentrations of Fe, Cu, Mn, and Al compared with the other seasons. The highest concentrations of Fe, Mn, and Al were found in fur taken in winter, with the lowest levels of Zn. Positive correlations were found between the content of iron and manganese, iron and aluminium, and manganese and aluminium in the coat of Hucul horses. A clear inter-individual and inter-stable variability was found, which may indicate the need for further research that also takes into account other factors.
该研究的目的是评估在波兰东南部两个不同设施中饲养并以当地饲料喂养的健康胡库尔马被毛中选定微量元素（如铁、铜、锰、锌和铝）的季节性变化。研究用的被毛在秋季、冬季和春季从24匹马身上采集。同时还测定了饲料中元素的浓度。采集日期对胡库尔马被毛中分析的微量营养素浓度有显著影响。夏季采集的被毛中锌浓度最高。与其他季节相比，秋季采集的被毛中铁、铜、锰和铝的浓度最高。冬季采集的被毛中铁、锰和铝浓度最高，锌含量最低。在胡库尔马的被毛中，铁与锰、铁与铝、锰与铝的含量之间存在正相关。发现了明显的个体间和个体内变异性，这可能表明需要进一步开展研究，同时考虑其他因素。
