This study was conducted to determine the fibre and follicle characteristics of private goats herds in different parts of Iran. Mean fibre diameter, coefficient variation of fibre diameter, percentage of cashmere and mohair, fibre efficiency, secondary to primary follicle ratio (S/P), number of primary and secondary follicles per unit area of skin and the percentage of shutdown follicles of Raeini, Nadoushan, Birjandi, Abadeh and Markhoz breeds of goats of different age and sex were measured. Duncan's new multiple range test was used to compare the groups. Results indicated that average cashmere diameter of Raeini, Nadoushan and Birjandi was 17.90±1.65, 17.09±0.95 and 18.83±1.99 and percentage of cashmere was 36.34±16.70, 45.62±12.20 and 54.80±10.4 respectively. Average S/P ratio of Raeini, Nadoushan, Abadeh, Birjandi and Markhoz breeds of goats was 13.02±0.13, 8.50 ± 1.60, 12.03±1.99, 8.92±1.75 and 6.55±1.20 and the percentage of shutdown follicles was 41.24±8.77. 26.59±17.81, 8.87±4.49, 24.98±7.81 and 10.80±8.25.
