Abstract Brazilian Goats have double hair coat composed of two fibres, coarse guard hair and fibre fine. The objective was to characterize the fibres and check if the fine fibre meets the standards for cashmere. We collected samples in Saanen, Alpine and Crossbreed goats. The analysis in scanning electron microscopy revealed that these individuals had fibre fine with an average diameter of 10.63 μm and coefficient of variation of 17.39 %, which is within the diameter range to be considered cashmere. The fibre fine had frequency scale of 7.57/100 μm and thickness of scale 383 nm. The results led to the recognition of cashmere fibres in goats born and raised in Brazil.

对巴西饲养的山羊的双层涂层的首次评估

摘要 巴西山羊有双层被毛，由粗粗和细纤维两种纤维组成。目的是表征纤维并检查细纤维是否符合羊绒标准。我们收集了萨嫩山羊、高山山羊和杂交山羊的样本。扫描电镜分析显示，这些个体的纤维细度平均为10.63 μm，变异系数为17.39%，属于羊绒的直径范围。细纤维的频率标度为 7.57/100 μm，标度厚度为 383 nm。结果导致人们在巴西出生和饲养的山羊中识别出羊绒纤维。
