Ben Walling knows all about the effects of Mycoplasma bovis on livestock and people — and he believes phased eradication of the disease is the best bet.
Long-term management might have made ''life a bit easier'' in the short term but the Northern Southland farmer and contractor believed it would mean ''millions'' of animals would die over the long term.
But to ensure eradication was successful, farmers had to help, otherwise the Ministry for Primary Industries did not have a hope of success, he said.
Mr Walling received calves from Southern Centre Dairies, the Southland dairy operation which is believed to be the first farm infected.
When the calves turned up at his property, some were so sick they had to be carried off the truck and nine were dead by the next day, he said.
