这项研究的目的是对Akkaraman的胎盘特征进行分类,Morkaraman,Karayaka,Awassi,马利亚,和巴夫拉绵羊品种采用层次聚类方法。总的来说,240个单独的数据记录被用作实验材料。胎盘特征,如子叶总表面积,小子叶和大子叶长度,小子叶深度,等。被用作解释变量来对品种特征进行分类。分层聚类与欧几里得距离最近邻方法一起使用,以对绵羊品种的变异进行分类。因此,六个品种被分成三个集群:第一个集群由巴夫拉组成,Karayaka,和Awassi品种;第二个由Akkaraman和Malya品种组成;第三组仅包括Morkaraman品种。巴夫拉和卡拉亚卡被认为是最近的品种,在胎盘特征方面的相似性为98.7%。Akkaraman和Malya品种的相似率为97.5%,而Bafra的比例为96.8%,Karayaka,和Awassi品种。Akkaraman的相似之处,Karayaka,Awassi,马利亚,巴夫拉绵羊的品种估计为95.7%。发现绵羊品种之间的总体相似性为93.2%。这项研究的结果可能是有用的选择工具的繁殖和可用于选择品种的饲养。
The aim of this study was to classify placental characteristics of Akkaraman, Morkaraman, Karayaka, Awassi, Malya, and Bafra sheep breeds using the hierarchical clustering method. In total, 240 individual data records were used as experimental material. Placental characteristics such as total cotyledon surface area, small and large cotyledon length, small cotyledon depth, etc. were used as explanatory variables to classify the breeds\' characteristics. Hierarchical clustering was used with the nearest neighbour method with Euclidean distance in order to classify the sheep breeds\' variations. As a result, six breeds were separated into three clusters: the first cluster consisted of Bafra, Karayaka, and Awassi breeds; the second consisted of Akkaraman and Malya breeds; and the third cluster included only the Morkaraman breed. Bafra and Karayaka were pointed as the nearest breeds, with a similarity of 98.7% in terms of placental characteristics. The similarity rate of the Akkaraman and Malya breeds was at a level of 97.5%, whereas it was 96.8% for Bafra, Karayaka, and Awassi breeds. The similarity of Akkaraman, Karayaka, Awassi, Malya, and Bafra sheep breeds was estimated as 95.7%. The overall similarity was found to be at a level of 93.2% among sheep breeds. The outcomes of the study might be useful as a selection tool for reproductivity and can be used to select the breed to be reared.
