Am I confused here. I read the report that the Canadian? holstien was 61/2 years old. That the cow was a heifer. Heifer= cow that has not yet had a calf. 6 1/2 years ago I beleive there was no ban on feeding cattle ground up animal waste. Mostly produced and imported to Canada from the US.If this was a holstien milk cow 6 1/2 years old and has been slaughtered and sold as beef there really is something wrong. Help me out here. Regards
