Genome-wide association studies for conformation traits in the Turkish Holstein cattle population.

ABSTRACT:

Background

Conformation traits (CNTs) are part of the selection goals that significantly affect cow economic efficiency, health, welfare, and productive life in the dairy industry.

Aims

This study focused on a genome-wide association study (GWAS) and genetic parameters estimation for 21 CNTs, including udder, leg-foot, body, type, and final classification traits in the Turkish Holstein (THol) dairy cattle population.

Methods

A restricted maximum likelihood with a univariate model including the fixed effects of herd-year-season and days in milk was used. The total dataset consisted of CNTs records and Affymetrix BovineSNP54K data for 3,008 THol cows that calved from 2019 to 2022. The gene ontology and Kyoto Encyclopedia of genes and genome pathway databases were used t
