摘要

这项研究的西班牙目的是对阿尔及利亚拉古亚特地区的两个土著山羊品种进行表型表征，并评估年龄和性别对形态生物学特征的影响。共分析了312只动物：58只Mekatia品种的雌性和254只阿拉伯品种的雌性（44只雄性和210只雌性）。结果表明，Mekatia品种的特点是短发（96.55%），而阿拉伯品种的特点是长发（男性为100%，女性为92.38%）。两个种族的大多数动物都是多色的（≥3种颜色）。半下垂的耳朵在Mekatia（48.28%）中最多，而在阿拉伯，下垂的耳朵占主导地位（男性为79.55%，女性为75.72%）。在数量性状上，这两个品种都被归类为大品种。年龄的影响显示在一半以上的测量中，随着年龄的增长，动物的大小普遍增加（p English这项研究的目的是对阿尔及利亚拉格胡亚特地区的两种土著山羊品种进行现象学表征，并评估年龄和性别对形态生物特征的影响。共调查了312只动物：58只来自Mekatia品种的雌性和254只来自阿拉伯品种的雌性（44只雄性和210只雌性）。结果表明，Mekatia品种的特点是短发型（96.55%），而阿拉伯品种的特点是长发型（男性100%，女性92.38%）。这两种品种中的大多数都是多色（≥3种颜色）。半下垂的耳朵在梅卡蒂亚（48.28%）占多数，而在阿拉伯，下垂的耳朵占主导地位（男性和女性分别为79.55%和75.72%）。关于数量性状，这两种品种都被归类为大型。一半以上的测量显示了年龄效应，随着年龄的增长，动物的体型总体上会增加（p＜0.05）。除两个特征（耳朵长度和坐骨宽度）外，所有测量都显示出显著的性二态性（p＜0.05）。这项研究的结果可以为阿尔及利亚拉格胡亚特地区山羊品种梅卡蒂亚和阿拉伯的描述和标准化提供依据。
