Abstract
Simple Summary Fertility and hatchability are important reproductive traits that directly influence chick production and the efficiency of poultry breeding programs. However, genetic improvement of these traits is challenging because they are influenced by many genes and environmental factors. This study evaluated fertility rate, hatchability of fertile eggs, and hatchability of eggs set in Thai native chickens using pedigree and genomic information. Three genetic evaluation methods were compared: pedigree-based BLUP (PBLUP), single-step genomic BLUP (ssGBLUP), and weighted single-step genomic BLUP (WssGBLUP). The results showed that genomic approaches improved prediction accuracy compared with pedigree-based evaluation, with WssGBLUP providing the highest accuracy and reliability. Several candidate genes associated with reproductive performance were identified, particularly on the Z chromosome. These findings support the implementation of genomic selection to improve reproductive efficiency and accelerate sustainable genetic improvement in Thai native chicken populations.
Abstract In dairy farming, reproductive efficiency is vital to both profitability and sustainability. However, years of selective breeding for increased milk yield have adversely affected reproductive potential. This study aimed to pinpoint genomic regions and identify potential candidate genes associated with reproduc...

Goats (Capra hircus) are among the world’s most important livestock, providing milk, meat, and fiber across diverse agro-ecological zones. Traditional breeding relying on pedigree-based estimated breeding values (EBVs) has driven steady genetic progress but is constrained by long generation intervals and limited accura...

Proper analysis of phenotypic data is essential for reliable genomic prediction (GP) and sustained genetic gain in breeding programs. In this study, we used phenotypic and genotypic data generated from the winter wheat breeding program of Deutsche Saatveredelung AG (DSV), Lippstadt, Germany, comprising 1,941 genotypes...
