Veziroğlu, B.
In this thesis study, the live weight after shearing, the greasy fleece yield and the clean fleece percentage of Norduz ewes in different conditions were investigated. The animal material consisted of a total of 260 head of Norduz ewes including 52 head ewes in different flocks that bred in the villages of Dolaylı, Geçerli, Geziyurt, Oğuldamı, and Taşınacak neighbourhoods of Gürpınar in Van province. Norduz ewes were sheared using shearing scissors at the end of June and beginning of July. Each of sheep greasy fleece was weighed using electronic digital hand weighing scales with 10 g sensitivity. After shearing of ewes, live weight was determined using electronic digital weighing scale with 100 g sensitivity. Fleece samples were taken as sufficient quantity for analysis, according to the sampling technique, from area of the last rib on the right shoulder of 12 head of ewes in each flock. Then analysis of clean fleece percentage was performed in the laboratory at the Yüzüncü Yıl University, Agricultural Faculty, and Department of Animal Science. SAS package program was used for the statistical analysis of the data obtained.For the Norduz ewes, the effect of shearing age on greasy fleece yield was not significant (p>0.05) but the effect of shearing age on live weight was significant (p<0.01) in Dolaylı, Geçerli, Geziyurt, Oğuldamı, and Taşınacak neighbourhoods. When all the farms were generally evaluated, the effect of shearing age and running farm from sources of variation examined the effect on greasy fleece yield was found insignificant (p>0.05), the effect of live weight after shearing is significant statistically (p<0.01). Least-squares means for greasy fleece yield of Norduz ewes raised in Dolaylı, Geçerli, Geziyurt, Oğuldamı, and Taşınacak neighbourhoods were 2.01±0.01, 2.08±0.01, 1.94±0.01, 2.11±0.01 and 2.11±0.01 kg. When all the farms were generally evaluated, least-squares mean for greasy fleece yield of Norduz ewes was 2.05±0.04 kg. The effect of shearing age on live weight in the farms of Dolaylı, Geçerli, Geziyurt, Oğuldamı and Taşınacak was significant (p<0.01). For Norduz ewes, in average, live weight after shearing in Dolaylı, Geçerli, Geziyurt, Oğuldamı ve Taşınacak neighbourhoods were found as 53.21±0.25, 54.30±0.24, 51.25±0.36, 55.08±0.29, and 54.93±0.30 kg while all the farms' average was found as 53.76±0.13 kg.Averages for clean fleece pevcantage of Norduz ewes in Dolaylı, Geçerli, Geziyurt, Oğuldamı, and Taşınacak neighbourhoods were found as 64.25±0.44%, 67.76±0.39%, 63.50±0.54%, 66.68±0.51%, and 64.06±0.36%, respectively. Average for clean fleece percentage was fourd as 65.25±0.20% in all the farms.
