Pashmina, a specialty fibre, grows as an undercoat from the follicles of Pashmina goats. The number and type of follicle constitute important determinants for quantity and quality of pashmina produced. Hence, a study was conducted to evaluate the follicle characteristics of Changthangi goats of Ladakh region. Skin samples of young (<1 year) and adult (>1 year) Changthangi goats from different body regions viz.; abdomen, flank, neck, back and thorax were collected and preserved in 10% neutral buffered formalin. Primary and secondary follicles and S/P (secondary to primary) follicle ratio were determined for different regions of the body. The study revealed difference in the number of follicles and S/P ratio between different body regions. Age-wise comparison showed variation in the S/P ratio between young and adult goats. It was concluded that yield and quality of pashmina from Changthangi goats depend on the age as well as the area of the body from which pashmina is harvested. Evaluation of S/P ratio in flank and back regions at the young age may prove a reliable predictor for pashmina yield in the adults.
