My cousin, Atma, runs the dairy down at the farm. One of the calves became quite ill over a period of ten to fifteen days, but the mother didn’t seem to care for it, generally ignoring it. After the calf died - from a ruptured intestine - the mother refused, or was unable, to produce any milk. They created this surrogate toy calf frame and stretched the dead calf’s skin over it and placed it next to the mother, who plays with it, licks it, pushes it around, and produces milk again.
