The shearing time (shorn once and twice in year) effected on wool characteristics were studied. 58 female Baluchi sheep 1-3 ages from Abas Abad station in east-north of Iran were selected and divided into once and twice shearing groups for two years. Wool samples from right midside were collected and the traits fleece weight, staple length at shoulder, flank and rump regions, fiber length, average fiber diameter and diameter coefficient of version, tenacity and breaking force were studied. The data were analyzed by repeated measurement and genera] linear model (GLM) using SAS software package. The Spring fleece weight (1.8910.05 versus 1.5710.05 kg) and staple length (9.3210.22 versus 8.0110.1 km) and variation fibre length for once or twice shearing time res. were. (p<0.0005)significant. The total fleece weight of twice (2.23 kg) was more than that of once shorn (1.85kg) but was not significant..
