The bond between dairy cows and their calves is emotionally significant for both animals, making early separation one of the most welfare-impactful events in dairy production.
The cow-calf bond is neurobiologically real: oxytocin, the bonding hormone, is elevated in both cow and calf following birth, and separation disrupts a genuine attachment. The distress of both animals during separation is observable and persistent. Extended maternal contact programs that allow nursing before weaning represent a meaningful welfare improvement that some farms are adopting commercially.
