Erciyes Üniv Vet Fak Derg 2019; 16(3): 218-223.Özet: Çalışma Hasmer koyunu mandibula'sı üzerinde bazı morfometrik değerleri ortaya koymak amacıyla yapılmıştır. Çalışmada Bahri Dağdaş Tarımsal Araştırma Enstitüsü'nden temin edilen reforme erişkin 8 adet Hasmer koyunu mandibula'sı kullanıldı. Hasmer koyununun mandibula'sı 19 noktadan ölçülmüş ve elde edilen değerler diğer koyun ırklarıyla karşılaştırılmıştır. Araştırmada mandibula'nın morfometrik incelemeleri dijital kumpas yardımıyla ölçülerek incelemeye ait veriler aritmetik ortalama ve standart hata ile belirlenmiştir. Hasmer koyununun mandibula uzunluğu 186.30±9.30 mm., mandibula yüksekliği ise 108.68±2.36 mm. olarak ölçülmüştür. Ölçülen bu değerler diğer koyun ırklarıyla bazı farklılıklar gösterdiği tespit edilmiştir. Bu çalışmada ayrıca, klinik açıdan önemli olan nervus mentalis ve n. mandibularis'in içinden geçtiği for. mentale ve for. mandibula'nın topografik olarak yerleri belirlenmiştir. Hasmer koyununda yapılan uzunluk korelasyon analizi bulgularına göre uzunluk U1 ve U3 arasında, uzunluk U1 ve U12 arasında uzunluk U2 ve U5 arasında, uzunluk U3 ve U6 arasında ve uzunluk U5 ve U6 arasında pozitif yönde güçlü korelasyon mevcut iken, uzunluk U7 ve U18 arasında negatif yönde güçlü bir korelasyon olduğu tespit edildi. Bu çalışma Hasmer koyunu ile ilgili yapılacak çalışmalar için kaynak bir araştırma olacağı düşünülmektedir.

In this study, reformed eight adult Hasmer mandibles which were obtained from Bahri Dagdas Agricultural Research Institute were used. The mandible of the Hasmer sheep was measured at 19 points and the obtained values were compared with the other sheep breeds. Morphometric analysis of the mandible was measured with digital caliper and the data of the study were determined by arithmetic mean and standard error. The height of the mandible was 108.68±2.36 mm. and the length of the mandible was 186.30±9.30 mm. according to these measurements. These measured values showed some differences with other sheep breeds. In this study, the topographic locations of the mental and mandible foramen through which the clinically important mental and the mandible nerve pass are determined. According to the results of length correlation analysis in Hasmer sheep, there was strong positive correlation between length U1 and U3, length U1 and U12 between length U2 and U5, length U3 and U6, and length U5 and U6, while length U7 and U18 had a strong negative correlation. There was a strong correlation. This study is thought to be a source research for the studies on Hasmer sheep.

The Effect of Gender Factor on Mandibular Morphometry in Abaza Goats

“…In the literature, with respect to the mandibular length and height were 167. 8 23 . This parameter was determined as 128.87 mm in female Abaza goats and 118.84 mm in male Abaza goats.…”

“…and 94.2 mm in Hemshin sheep18 , 152.4 and 87.0 mm in Morkaraman sheep,19 and Tuj sheep 147.8 and 85.4 mm19 , respectively. 157.6 and 95.7 mm in Mehra-ban sheep,20 181.6 and 107.9 mm in Barbados sheep,21 in Yankasa sheep,22 198.0±0.28 and 129.0±0.57 were reported as 186.30±9.30 and 108.68±2.36 mm in Hasmer sheep,23 in Awassi sheep 26 mandibular length 180.22±11.91 while Avdic et al24 ., reported that it was 176.0 and 99.6 mm in a study on sheep in Sarajevo. In Abaza goats 158,73 mm and 90,46 mm in females 148,72 and 88,60 mm in males respectively.…”

“…In Abaza goats, it was found to be 36.75 mm in females and 35.61 mm in males. In the studies, it was reported that the length between Gv and Cnd was 68.52 in Hemshin sheep18 and 74.58 ± 1.75 mm in Hasmer sheep23 77.50 mm. This parameter was determined as 63.57 mm in female Abaza goats and 63.33 mm in male Abaza goats.…”

“…In Abaza goats 158,73 mm and 90,46 mm in females 148,72 and 88,60 mm in males respectively. In the literature, it has been reported the mandibular height of the posterior alveolar edge of the 3rd molar tooth of Hasmer sheep23 37.47 ± 3.25 mm, from Hemshin sheep18 37.93 mm and Morkaraman sheep19 38.88 mm. In Abaza goats, it was found to be 36.75 mm in females and 35.61 mm in males.…”

“…This parameter was determined as 63.57 mm in female Abaza goats and 63.33 mm in male Abaza goats. The length of the first and last molar teeth (L8) has been reported as 57.2 mm in Hemshin sheep18 , in Hasmer sheep23 49.26 ± 3.11 mm, and 53.12 mm in Morkaraman sheep19 . In our study, it was measured as 58.28 mm in females and 53.66 mm in males Abaza goats.…”
