This study aimed to examine the diversity of phenotypic characteristics of female Alabio ducks ( Borneo) and their eggs in South Kalimantan, Indonesia.
A total of 200 18-month-old ducks and 300 eggs were selected using a survey method with multistage random sampling. These samples were obtained from two districts in the province of South Kalimantan [Banjar (BJ) districts and Tanah Laut (TL)]. The observed data were analyzed descriptively with variations using the independent -test for each location. Principal component analysis (PCA) was deployed to assess the overall variance and define variables with greater discriminatory power between individuals.
The observations on the body's physical characteristics and the eggs of Alabio ducks showed significant differences between ducks from BJ and TL areas ( < 0.05) except for yolk diameter, albumen height, albumen index, and Haugh unit (HU) ( > 0.05). Most egg quality traits from BJ were greater than those from TL, which include egg weight, egg length, egg width, yolk weight, albumen weight, shell weight, shell thickness, and egg shape index. The PCA revealed medium-to-high communalities in the phenotypic body characteristics of Alabio ducks and their eggs.
Significant physical characteristics and egg quality differences were found between the two locations, except for the albumen index and HU, with substantial variability within each trait. These traits could explain the total variation in the phenotypic characteristics of female Alabio ducks.
本研究旨在调查印度尼西亚南加里曼丹地区婆罗洲雌性阿拉比奥鸭及其蛋的表型特征多样性。
采用多阶段随机抽样调查法，选取了200只18月龄的鸭子和300枚蛋。这些样本取自南加里曼丹省的两个地区[班贾尔（BJ）区和塔纳劳特（TL）区]。对观测数据进行描述性分析，并对每个地点的数据进行独立t检验以分析差异。采用主成分分析（PCA）评估总体方差，并确定个体间具有更大区分能力的变量。
对阿拉比奥鸭的身体物理特征和蛋的观察表明，BJ和TL地区的鸭子之间存在显著差异（P<0.05），但蛋黄直径、蛋白高度、蛋白指数和哈夫单位（HU）除外（P>0.05）。BJ地区的大多数蛋品质性状大于TL地区，包括蛋重、蛋长、蛋宽、蛋黄重、蛋白重、蛋壳重、蛋壳厚度和蛋形指数。主成分分析显示，阿拉比奥鸭及其蛋的表型身体特征具有中到高的共同度。
除蛋白指数和哈夫单位外，两个地点之间在身体特征和蛋品质方面存在显著差异，且每个性状内存在较大变异性。这些性状可以解释雌性阿拉比奥鸭表型特征的总变异。
