A North Otago dairy farmer says he is in a state of disbelief after realising 60 rising 2-year Friesian heifers had been taken from his farm.
Russell Hurst, of Awamoko, said the animals, taken between the week before Christmas and New Year's Day, could be worth $100,000.
He and his staff went ''around and round the farm in circles'' double-checking the mobs on the 2500ha farm to make sure the animals had been stolen.
''It's just disbelief, really,'' Hurst said.
''Anger ... I think if we'd seen real evidence - a hole cut in a fence, maybe - but this is just disbelief at how they can vanish with almost no trace. There is no trace.
