Evidence that farm animals experience grief-like states and what this means for welfare practices around separation and loss.
If farm animals experience grief, then standard industry practices that routinely break social bonds - calf separation, mixing groups, repeated pen moves, early mortality of pen companions - cause suffering that goes unrecognized in most welfare assessment frameworks. This does not mean animals grieve identically to humans, but it does mean that disruption of meaningful social relationships is a welfare harm that should be minimized where possible.
