In the linked article https://en.wikipedia.org/wiki/Heck_cattle (an attempt to breed back aurochs), this is amusing:

"Derek Gow, a British conservationist who operates a rare breeds farm at Lifton near Okehampton in Devon, bought a herd of 13 Heck cattle from Belgium in 2009.[15] The herd grew to 20 animals, but in January 2015 it was reported that Gow had had to slaughter most of them due to high levels of aggression, leaving just six."
