Data on skin thickness and growth dynamics of hair cover of meat cattle of Aberdeen-Angus, Hereford and Limousine breeds, freely raised on the farm of the Research Institute of Mountain Stockbreeding and Agriculture, Troyan, are provided. Skin measurements in the neck, the elbow joint and the middle of the last rib were measured and analysed as well as the structure of different fiber categories of the hair cover. The measurements of skin thickness were performed with the aid of the skin-fold caliper in seasons (winter and summer). The hair weights in 1cm , the length and percentage of the different fibers were determined. The animals surveyed show good adaptation plasticity in the process of generational change.
