Abstract

Morphometric studies in Lidia cattle are scarce due to the challenges of handling and approaching this breed of cattle. For this reason, the first morphological characterization of the breed was carried out using photogrammetry. In the present work, 264 adult individuals (184 males and 80 females), belonging to 21 different herds, were studied. A total of 20 morphological measurements and five indexes were determined in every individual. There were many positive correlations between the measures, giving the model great morphostructural harmony. Considerable internal variability of the studied parameters was observed. This breed reflected significant sexually dimorphic features and internal morphological differences between the different genetic lines of the breed. cattle are small and mostly have a sub-concave profile (58.4% males and 69.7% females). The male proportionality indexes and the relative depth of the thorax indicated great muscular development of the anterior third and high thoracic capacity. The phaneroptic information describes a mostly black animal with black mucous and hooves and an outstanding development of the dewlaps and the tail in the males.

摘要

由于处理和接近利迪亚牛存在挑战,关于该品种牛的形态测量研究很少。因此,首次使用摄影测量法对该品种进行了形态特征描述。在本研究中,对来自21个不同牛群的264头成年个体(184头雄性和80头雌性)进行了研究。对每头个体测定了总共20项形态测量指标和5个指数。各项测量指标之间存在许多正相关关系,使模型具有良好的形态结构协调性。观察到所研究参数存在相当大的内部变异性。该品种表现出显著的两性异形特征以及不同遗传系之间的内部形态差异。利迪亚牛体型较小,大多具有次凹形轮廓(雄性占58.4%,雌性占69.7%)。雄性比例指数和胸部相对深度表明前三分之一部位肌肉发达且胸腔容量大。外观信息描述该品种大多为黑色动物,有黑色黏膜和蹄子,雄性的垂皮和尾巴发育突出。
