Genomic selection has transformed animal breeding by enabling faster genetic improvements in livestock populations. While this technology has accelerated breeding progress, its implementation in some widespread cattle breeds has led to higher rates of inbreeding. This study examines how genomic selection impacts genetic diversity across five European cattle breeds, with particular attention to potential risks for smaller or locally adapted populations.
Why it matters
Understanding the effects of genomic selection on genetic diversity is critical for sustainable breeding programs, especially in local breeds that may be more vulnerable to loss of genetic variation. Maintaining adequate genetic diversity is essential for breed adaptability, disease resistance, and long-term population viability in both commercial and conservation contexts.
Genomic selection has revolutionized animal breeding and accelerated genetic gains in breeding programs. However, the introduction of genomic selection in some cosmopolitan breeds has also been associated with increased inbreeding rates, raising concerns about the potential effects of genomic selection on genetic diversity in smaller or local breeds.
