Ms LeDoux has brought the bulls from her north-eastern Kansas ranch to the annual National Western Stock Show in Denver, a three-week livestock fair in January at which 15, 000 farm animals are shown, ranging from cattle and sheep to chickens and llamas.
Farmers' Union of Wales president Emyr Jones, who has lost stock on his farm in Bala, Gwynedd, said the review would do little to help farmers who had lost livestock, had damaged buildings and shortages of fodder.
