Türkiye, Ege Bölgesi’nde Farklı Yaş Gruplarındaki Sakız Koyunları Chios Üzerine Araştırma

Özbilgi/Amaç: Bu çalışma Türkiye, Ege Bölgesi’nde özel bir işletmede yetiştirilen farklı yaş gruplarındaki 109 baş Sakız koyunun canlı ağırlığı ve bazı vücut ölçüleri üzerine vücut kondisyon skorunun etkileri ile özellikler arasındaki ilişkilerin belirlenmesi için yürütülmüştür. Materyal ve Metot: Hayvanlar Grup 1 6-12 ay; n:42 , Grup 2 13-18 ay, n: 18 , Grup 3 19-24 ay, n:25 ve Grup 4 25 ay ve yukarısı, n:24 olarak 4 yaş grubuna ayrılmıştır. Çalışmadaki hayvan materyali 09.00 ile 16.30 saatleri arasında mer’a da otlatılmaktadır. İçme suyu ad-libitum olarak sağlanmaktadır. Çalışmada vücut ölçüleri olarak Vücut Uzunluğu VU , Cidago Yüksekliği CY , Göğüs Derinliği GD , Göğüs Çevresi GÇ ve İncik Çevresi İÇ dikkate alınmıştır. CY ve GD bir ölçü bastonu vasıtasıyla ölçülmüştür. VL, GÇ ve İÇ ise bir ölçü şeridi kullanılarak ölçülmüştür. Bireysel canlı ağırlıklar otlatma öncesi sabahın erken saatlerinde bir baskül yardımıyla belirlenmiştir. Bu çalışmada, koyunların vücut kondisyon skorunun VKS değerlendirilmesinde Russel 1984 tarafından tanımlanan beş-derecelendirme sistemine göre yapılmıştır. Koyunlar VKS’na göre 4 gruba 2.0, 2.5, 3.0, 3.5≤ ayrılmıştır. Bulgular ve Sonuç: Sakız koyunları için canlı ağırlık CA , VU, CY, GD, GÇ ve İÇ’ne ait tüm ortalamalar sırasıyla 37.02 kg, 85.01 cm, 69.27 cm, 52.11 cm, 93.44 cm ve 9.16 cm olarak bulunmuştur. VKS’na göre CA, VU, CY, GD, GÇ ve İÇ’ne ait ortalamalarda artış söz konusudur. CA, VU, CY, GD, GÇ ve İÇ’ne ait en yüksek ortalamalar 3.5≤ VKS grubunda, en düşük ortalamalar ise 2 VKS grubunda tespit edilmiştir. CA, VU, CY, GÇ ve İÇ üzerine yaşın etkisi istatistik bakımdan önemli bulunurken P0.05 . Çalışmada, CA, VU, CY, GD, GÇ ve İÇ üzerine VKS’nun etkisi önemli bulunmuştur P

Investigation on Sakiz Ewes Chios from Different Age Groups in Aegean Region, Turkey

Background and Aim: The present study was carried out to establish relationships among traits and the effect of body condition score on body weight and some body measurements of 109 Sakiz ewes from different aged groups raised at a private farm in Aegean Region, Turkey. Material and Method: The animals were enrolled in four age groups as Group 1 06-12 months, n: 42 , Group 2 13-18 months, n: 18 , Group 3 19-24 months, n: 25 and Group 4 25 months and above, n: 24 . The animal material in the study was released grazing at 9.00 and 16.30 at pasturage. Potable water was obtained as ad libitum. Body Length BL , Wither Height WH , Chest Depth CD , Chest Girth CG and Shinbone Circumference SC were considered as some body measurements of ewes in study. WH and CD were measured by a measuring cane. BL, CG and SC were measured by using a measuring tape. Individual body weights were determined by a weighing scale in wee hours of the morning before grazing. In this study, assessment of body condition score BCS of sheep was performed within five-rank system by Russel, 1984. Sheep were enrolled in 4 groups 2.0, 2.5, 3.0, 3.5≤ according to BCS. Results and Conclusion: Overall means of body weight BW 37.02 kg, BL 85.01 cm, WH 69.27 cm, CD 52.11 cm, CG 93.44 cm and SC 9.16 cm were found for Sakiz ewes. The means of BW, BL, WH, CD, CG and SC were increased as BCS. The highest means of BW, BL, WH, CD, CG and SC were determined by the group with score of 3.5≤ and the lowest means were found by the group with score of 2. The effect of age on BW, BL, WH, CG and SC were found statistically significant P0.05 . In study, the effect of BCS on BW, BL, WH, CD, CG and SC were found significant P
