Additional file 3 of Reliability of genomic evaluation for egg quality traits in layers

Additional file 3 Bias of (G)EBVs in candidate populations with respect to cC traits. Traits: EW: Egg Weight; ESC: Eggshell Colour; ESS: Eggshell Strength; AH: Albumen Height; ESshape: Eggshell shape index. Candidates: C1: male candidates from G1; C2: male candidates from G1 and G2; F: female candidates from G2. Multi-trait evaluations were performed for the five traits using BLUP (EBV) and ssGBLUP (GEBV) methodologies. Case 1: evaluation at birth; Case 2: evaluation at 60 weeks of age; Case 3: evaluation at 140 weeks of age

附加文件3：候选群体中（G）估计育种值[(G)EBVs, Genomic Estimated Breeding Values]针对cC性状的偏差。性状说明：EW：蛋重（Egg Weight）；ESC：蛋壳颜色（Eggshell Colour）；ESS：蛋壳强度（Eggshell Strength）；AH：蛋白高度（Albumen Height）；ESshape：蛋形指数（Eggshell shape index）。候选群体分组：C1：来自G1群体的公畜候选个体；C2：来自G1与G2群体的公畜候选个体；F：来自G2群体的母畜候选个体。本研究采用最佳线性无偏预测（BLUP, Best Linear Unbiased Prediction，其估计育种值记为EBV）以及单步基因组最佳线性无偏预测（ssGBLUP, single-step Genomic Best Linear Unbiased Prediction，其估计育种值记为GEBV）两种方法，对上述5个性状开展多性状评估。评估案例分为3组：案例1：出生时进行评估；案例2：60周龄时进行评估；案例3：140周龄时进行评估。
