Genome-wide association analysis revealed novel candidate genes for body measurement traits in indigenous Gudali and crossbred Simgud in Cameroon.

ABSTRACT:

Background

The genetic potential of Central African cattle for enhanced productivity remains largely unexplored. The absence of systematic pedigree recording and performance monitoring represent a major obstacle to implementing informed breeding strategies aimed at improving their production. To address this gap, we performed a genome-wide association analysis (GWAS) on a total of 856 animals genotyped with the GGP Bovine 100K array. The analysis focused on identifying genomic regions and candidate genes associated with body traits in a local Zebu (Gudali) and its crossbreed with the European Simmental (Simgud), using mixed linear models (MLM).

Results

The SNP-based heritability for the four body traits studied varied between 0.23 ± 0.12 for the height at wither (HAW) to 0.4
