Abstract

The aim of this study was to compare the external and internal egg quality of three layer strains namely Bovan Nera, ISA Brown and FUNAAB Alpha. One hundred and fifty eggs sampled from 120 birds per strain from 35 to 45 weeks of age were used for the study. Data collected were analysed using one way analysis of variance in a completely randomized design. ISA Brown had significantly (P<0.01) the heaviest eggs on the average at 45 weeks, followed by Bovan Nera and FUNAAB Alpha. The egg quality characteristics of Bovan Nera and ISA Brown were similar but significantly (P<0.05) superior to FUNAAB Alpha in egg width, egg volume, egg surface area and albumen weight. FUNAAB Alpha was significantly (P<0.05) the most superior in yolk weight only. Three principal components (PC1, PC2 and PC3) were produced from each strain after principal component analysis and varimax rotation. Estimation of breeding values based on the three principal components could be used for the selection and improvement of egg quality variables in each strain instead of isolated traits.

对3个品系蛋鸡的蛋品质特征进行主成分分析

本研究的目的是比较Bovan Nera、ISA Brown和FUNAAB Alpha三个蛋鸡品系的内外蛋质量。研究使用了从每种35至45周龄的120只鸟身上取样的150只蛋。在完全随机设计中，使用单向方差分析对收集的数据进行分析。平均45周时，ISA Brown的卵子最重（P<0.01），其次是Bovan Nera和FUNAAB Alpha。Bovan-Nera和ISA-Brown的蛋质量特征相似，但在蛋宽、蛋体积、蛋表面积和蛋白重量方面显著优于FUNAAB-Alpha（P<0.05）。FUNAAB-Alpha仅在蛋黄重量方面最为显著（P＜0.05）。经过主成分分析和方差最大旋转，每个菌株产生三个主成分（PC1、PC2和PC3）。基于三个主要成分的育种值估计可以用于选择和改善每个品系的鸡蛋质量变量，而不是孤立的性状。

期刊介绍： Journal of the Indonesian Tropical Animal Agriculture (JITAA) is a double blind peer-reviewed publication devoted to disseminate all information contributing to the understanding and development of animal agriculture in the tropics by publication of original research papers. The journal covers all aspect relating to Animal Agriculture, including: -Animal breeding and genetics -Animal feeding and nutrition -Animal reproduction -Animal biotechnology -Animal physiology -Animal production and technology -Animal products technology -Animal management and economics -Animal products processing and animal by-products -Animal microbiology -Livestock farming systems -Other related topics in relation to animal science. The topics of research are not only on Indonesian tropical animal agriculture, but also on other tropical regions of the world.
