The follicle arrangement and secondary to primary follicle ratio (S/P) were studied in the skin of nine male and nine female Markhoz goats breed from one week to 16 weeks of age. The skin samples were taken from mid-side area of each animal in nine stages every other week. The follicles were arranged in groups, predominantly including three primary and several secondary follicles. Each primary follicle associated with sudoiferous gland, bilobed sebaceous gland and erector pili muscle and each secondary follicle associated with only monolobed (and some bilobed) sebaceous gland. The mean of S/P ratio was significantly different in different stages (except stages six and seven) (P ? 0.05). The maximum S/P ratio was observed at 16 weeks after birth. Effect of sex and interaction of sex and age on S/P ratio was not significant (P > 0.05).
