摘要

Etiope哥伦比亚克里奥尔毛羊(OPC)多年来一直是农民和土著人民的动物蛋白供应商。然而,这种动物遗传资源的品种状况尚未达成一致,这有利于加剧引进外国品种所产生的威胁,因为如果不明确Etiope和OPC的品种分类,很难让农民意识到他们应该保护、改进什么以及为什么要保护、改进。本研究的目的是从形态学和显象学的角度描述OPC,为其合适的特性和品种分类做出贡献。这项研究在位于科尔多瓦和玻利瓦尔省(哥伦比亚)的九个农场进行,对92只母羊的6个显象光学性状和7个形态定性特征进行了评估。这些特性的评估是在摄影相机和数字测角仪的支持下通过直接观察进行的。数据分析是通过使用InfoStat®软件估计绝对频率和相对频率进行的。表位通常为暗红色(43.48%)或非常暗红色(44.57%),毛色为黑玫瑰色(93.48%),耳朵水平定向(100%),头部轮廓为亚凸(72.83%),大腹便便(81.52%),臀部倾斜(86.96%),蹄有大理石花纹(81.32%),偶尔出现垂肉(24.28%),乳房有色素(13.19%)。总之,本描述集中在表位羊身上,并详细阐述,提供了有助于定义决定该族群归属的特征的要素,以及有助于就这些本地绵羊的适当品种分类达成共识的要素。

Caracterización morfológica y faneróptica de hembras Ovino de Pelo Criollo Colombiano “OPC” Sudán
Etiope Colombian creole woolless sheep (OPC) have been suppliers of animal protein throughout years for peasant and indigenous people. However, the breed status of this animal genetic resource has not been agreed yet, which has favored to accentuate the menace produced by the introduction of foreign breeds since without clarity about the breed classification of Etiope and OPC in general, it is difficult to create awareness among farmers about what they should conserve, improve and why. The objective of this research was to describe morphologically and phaneroptically Etiope OPC, for contributing with its suitable characterization and breed classification. This study was developed in nine farms which were located in the Cordoba and Bolivar Departaments (Colombia), six phaneroptical traits and seven morphological qualitative characteristics were evaluated in 92 ewes. The assessment of these characteristics was made by direct observation with the support of a photographic camera and a digital goniometer. Data analysis was made through the estimation of absolute and relative frequency with the software InfoStat®. Etiopes were generally dark red (43.48%) or very dark red (44.57%) coat color, black-rosy mucosae (93.48%), horizontally oriented ears (100%), sub-convex cephalic profile (72.83%), potbellied (81.52%), inclined rump (86.96%), marbled hooves (81.32%), with occasional wattle presences (24.28%) and pigmented udders (13.19%). In conclusion, this description focused on Etiope sheep, and elaborated minutely, provided elements which help to define the traits which determine the belonging to this ethnic group as well as they help to reach a consensus on the appropriate breed classification of these autochthonous ovines.
