Follicle and fibre characteristics of Indian pashmina goats.

Abstract

The hair follicle and fibre characteristics of Cheghu and Changthangi pashmina goats are reported. The average numbers of primary follicles mm-2 were 6.80, 5.20, 5.67 and 4.00; secondary follicles 42.40, 27.10, 38.56 and 29.67; secondary to primary follicle ratio 6.46, 5.78, 6.79 and 7.60; total follicle population 49.20, 32.30, 44.22 and 33.67 in Cheghu females, Cheghu males, Changthangi females and Changthangi males, respectively. The breed difference was not significant for any of these traits, but the sex difference was significant for a number of secondary follicles and total density. Study of fleece characteristics of Cheghu goats in a 1 cm2 area of five body regions, namely, neck, shoulder, mid-side, flank and abdomen, showed that females had finer fibres (12.06 to 12.12 micron) than males (13.04 to 13.64 micron) in all regions. The pashmina length, pashmina diameter and fibre thickness ratio were significantly different between sexes and between body regions but hair/pashmina ratio and pashmina yield were significant for sex and body regions, respectively.
