Abstract

The aim of the study is to characterize Begait cattle using morphometric and qualitative traits. The breed was kept under farm and ranch management systems in Western Tigray, Ethiopia. A total of 368 Begait cattle which included 24 male Begait cattle were selected using simple random sampling method and the data were analyzed using statistical packages for social sciences and statistical analysis software. Begait cows exhibited chest girth of 152.8±0.40 cm, height at withers of 129.1±0.28 cm, backline length (loin length + back length) of 88.4±0.26 cm and tail length of 96.2±0.44 cm. Whilst Begait breeding males showed chest girth of 170.7±1.35 cm, height at withers of 145.1±1.18 cm, backline length of 90.0±1.13 cm and tail length of 108.2±1.29 cm. The skeletal measurements of Begait cattle are good indicators of the breed as a potential dual-purpose breed and the gene could be improved through selection. Humera ranch should own superior male Begait cattle for genetic improvement of the breed. The correlation was significant (P<0.01) among most of the morphometric traits of Begait cows. The most frequently observed coat color patterns of Begait cows were pied (42.4%) and spotted (33.1%) whilst the body coat color types of the cows were combination of black and white (34.6%) and brown (29.7%). All males were humped and majority of Begait cows (88.1%) were humpless. Begait cows had concave face profile (72.1%) and roofy rump profile (69.2%). The information generated from this research work will be used for planning Begait cattle genetic resources management in sustainable manner for the development of Regional and National economy. Key words: Characterization, Begait cattle, qualitative traits, morphometric traits.

埃塞俄比亚提格雷西部地区贝盖特牛的形态计量学和质量性状研究
该研究的目的是利用形态计量学和质量性状来表征贝盖特牛。该品种在埃塞俄比亚西部提格雷的农场和牧场管理系统下饲养。采用简单随机抽样的方法,选取贝盖特牛368头,其中雄贝盖特牛24头,采用社会科学统计软件包和统计分析软件对数据进行分析。乳牛胸围152.8±0.40 cm,肩高129.1±0.28 cm,背长(腰长+背长)88.4±0.26 cm,尾长96.2±0.44 cm。贝盖特繁殖雄性胸围为170.7±1.35 cm,肩高为145.1±1.18 cm,背长为90.0±1.13 cm,尾长为108.2±1.29 cm。贝盖特牛的骨骼测量是该品种作为潜在的双重用途品种的良好指标,该基因可以通过选择进行改良。Humera牧场应该拥有优良的雄性Begait牛,以便对该品种进行遗传改良。贝盖特奶牛的大部分形态计量性状之间的相关性极显著(P<0.01)。贝盖特奶牛最常见的被毛颜色类型为花斑(42.4%)和斑点(33.1%),而奶牛的体毛颜色类型为黑白混合(34.6%)和棕色(29.7%)。所有公牛均为驼峰,绝大多数(88.1%)为无驼峰。乳牛面部轮廓凹(72.1%),臀部轮廓翘(69.2%)。本研究所得的信息将用于规划以可持续方式管理巴吉特牛遗传资源,促进区域和国民经济的发展。关键词:性状,Begait牛,质量性状,形态计量性状。
