The present investigation aimed to evaluate the histomorphometric features of the skin of the Iranian native sheep (Bakhtiari breed). A total of 24 apparently healthy Iranian Bakhtiari sheep, aged 1–2 years were analysed and categorised on the basis of sex (12 females and 12 males). Samples were taken as small pieces from different regions of the skin, fixed and stained with H&E. The quantitative evaluations of different regions of skin were carried out using lattice line graticule (5 × 5) and light microscopy. The Student t-test and one-way ANOVA were used to analyse the data and detect significant differences. Results showed that the volume densities of different histological structures varied between sexes and among the different regions. No significant difference was observed in volume densities of sebaceous glands, arrector pili muscles and blood vessels, but the other parameters studied differed significantly among the regions. Except for the arrector pili muscle and connective tissue, the volume densities of other tissue structures were significantly affected by sex.
