The aim of this study is to investigate some physical characteristics of coarse fibre in Norduz goat which is a local breed of Eastern Anatolia in Turkey. Fibres are sampled from shoulder, thigh and back of 48 female Norduz goat between 14 years-old. Fibre length and diameters do not vary significantly according to age and part of body. Fibres obtained from 3 years-old goats are thickest (74.4 +/- 6.20 mu m) while these from goats one year-old were found thinnest as 53.7 +/- 2.93 (p<0.05) mu m. Breaking strength value is found higher in 3 years-old goats when comparing with I year-old goats (18.7 +/- 0.38 vs 17.2 +/- 0.27) (p<0.05). Fibre diameter and length is negatively correlated (477) (p<0.05) in 3 years-old goats. The diameter and the breaking strength of fibres sampled from back are highly correlated (0.94) (p<0.01) in 4 years-old goats. In addition, elongation rate is positively correlated with breaking strength (0.88) and diameter (0.95) for fibres sampled from back of 4 years-old goats (p<0.01).
