Traditional Cattle Herds' Diversity Hit by Selective Breeding

Decades of selective breeding and intensive agricultural practices have reshaped cattle genetics—often at the expense of valuable diversity preserved in traditional herds—according to new research from Aberystwyth University.

The authors of the study, published in Applied Animal Science, warn that safeguarding these genetic resources is critical for sustainable farming in the face of climate change and shifting global demands.

Traditional cattle herds often carry unique genetic profiles that provide resilience against disease, fertility advantages or adaptability to challenging environments.

The researchers argue that losing these populations would mean losing irreplaceable traits that could help future generations of farmers respond to global challenges.

The review highlights examples from breeds such as Ayrshire, Jersey and Hereford, where traditional populations remain distinct from their modern counterparts.

These herds are typically smaller, less intensively managed and more closely tied to local environments, making them vital for conservation and future breeding strategies.
