The erosion of genetic diversity limits long-term gain and impedes the sustainability livestock production. In South African (SA) dairy industry, major commercial breeds have been applying estimated breeding values (EBVs) and/or participating in Multiple Across Country Evaluations (MACE). transition to genomic (GEBVs) selection strategies requires monitoring inbreeding current genotyped animals, especially considering comparatively small population sizes global SA. This study aimed perform a...
Abstract Background Reproduction is a key feature of the sustainability species and thus represents an important component in livestock genetic improvement programs. Most reproductive traits are lowly heritable. In order to gain better understanding underlying basis these traits, genome-wide association was conducted for age at first calving (AFC), inter-calving period (ICP) scrotal circumference (SC) within South African Bonsmara breed. Phenotypes genotypes (120,692 single nucleotide...
