Abstract
In this study, the live weight after shearing, the greasy wool weight and, the clean fleece percentage of Norduz ewes in different breeding conditions were investigated. The animal material consisted of a total of 260 head of Norduz ewes including 52 head ewes at the different flocks raised in Dolayli (farm 1), Gecerli (farm 2), Geziyurt (farm 3), Oguldami (farm 4) and, Tasinacak (farm 5) neighbourhoods of Gurpinar province in Van city. Norduz ewes were sheared using shearing scissors between end of June and beginning of July. After shearing, ewes were weighted by using electronic digital weighing scale. Then, the sampling for clean fleece percentage were performed from area of the last rib on the right shoulder of 12 head of ewes in each flock. When all the farms were generally evaluated, the effect of live weight after shearing on the greasy wool weight was statistically significant (p<0.01). Least squares means for greasy wool weight at farm 1, farm 2, farm 3, farm 4 and, farm 5 were 2.03, 2.05, 2.05, 2.06 and, 2.06 kg, respectively. When all the farms were generally evaluated, the effect of age of ewe and farm on the live weight after shearing was statistically significant (p<0.01) in Norduz ewes. Least squares means for live weight after shearing at Dolayli, Gecerli, Geziyurt, Oguldami and, Tasinacak neighbourhoods were 53.21, 54.30, 51.25, 55.08 and, 54.93 kg, respectively. Means of clean fleece percentage were 64.25%, 67.76%, 63.50%, 66.68% and, 64.06% for Dolayli, Gecerli, Geziyurt, Oguldami and, Tasinacak neighbourhoods, respectively.

Summary
The most of sheep production in Turkey are carried out in extensive or semi-intensive systems. The most of sheep breeds reared in Turkey are characterized as rough-mixed wool genotypes and their wools are usually used to carpet, blanket, quilt and weaving socks. Turkey has an important place in the production of fleece with carpet type in the world. There is an increase for sheep production in Turkey and use of rough-mixed wool in the world (DAKA 2012, Bingöl and Bingöl 2015). In Turkey, the fine wool should be reduced in the textile industry and, the coarse wool should be mostly used increasing fleece yield (Çivi 1999, Alkan 2008). Wool is the most important raw material of the textile industry. Most of the native sheep breeds in Turkey have low meat and wool yields. This research was carried out in order to determine the live weight after shearing, the greasy fleece yield and, the clean fleece percentage in Norduz ewes under different breeding conditions
