Monitoring the elemental status of herd horses during their maintenance in the extreme conditions of Yakutia is one of the main problems requiring a more detailed study. The mineral composition of wool reflects the accumulated levels of macro- and microelements that gradually accumulate in its structure. The purpose of the research was to analyze the elemental status of Yakut horses based on their hair samples. We formed two groups of animals that differed in their conditions of detention: in the first group, the mares were kept in the traditional way without milking; the second group consisted of milking mares. More significant differences were observed in terms of macronutrients. Thus, significant differences were found in the content of magnesium – 1.44 times (P <0.01), potassium – 1.45 times (P <0.05), sodium – 1.6 times (P <0.01); unreliable differences are characteristic of calcium (in favor of animals of the first group). There were no significant differences in the content of essential trace elements between the studied groups; in terms of the concentration of toxic elements in the wool of the studied groups, the indicators were practically at the same level. In the future, it is proposed to conduct more extensive research on the mechanisms and processes of mineral accumulation in the coat of Yakut horses, depending on gender, age and other factors. This will make it possible to identify the reference ranges of the content of mineral elements and, on this basis, to assess and monitor the condition of these animals in winter by the elemental composition of wool.
