Abstract

VAN NIEKERK, W.A.; KEVA, S.; ROETS, M.  and  COERTZE, R.J.. The accuracy of Video Image Analysis (VIA) and Optical Fibre Diameter Analysis (OFDA) to measure fibre diameter of cashmere. S. Afr. j. anim. sci. [online]. 2004, vol.34, n.5, pp.143-144. ISSN 2221-4062.

The aim of this study was to evaluate two techniques, Optical Fibre Diameter Analysis (OFDA) and Video Image Analysis (VIA) that were used to measure fibre diameter of cashmere and guard hair produced by South African indigenous goats. The fibre measured by the OFDA technique was less fine than that measured by the VIA technique. The findings of this study suggests that more precise results are obtained with the VIA technique than with the use the OFDA method of measuring fibre diameter.

Keywords : VIA; OFDA; cashmere; diameter.
