The red trait was thus able to survive the attempts to eradicate it that came from all sides of the Holstein industry. It was inevitable that even when a red calf was culled, the herd owner rarely did anything to remove the dam from his herd and only hoped she would not have another red calf. Many red calves, born in both countries prior to the 1970s, were quietly disposed of, with a view to preserving the acceptance of their elite pedigrees.
