The pattern of after birth secondary follicle development in Markhoz goat breed

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).‎
