Dairy farmers facing years of recovery from M. bovis cull

WELLINGTON — Dairy farmers whose herds are culled through the Mycoplasma bovis eradication programme could be back in business within months, but for most it will take years to rebuild their herds to full strength, DairyNZ’s Andrew Reid said.

The 39 infected properties have been earmarked for “depopulation”, which means all their stock will be killed.

Mr Reid, who is DairyNZ’s general manager for the farmer-funded body’s team of advisers, said the process of restoring herds will depend on stock availability and the price farmers are prepared to pay.

“It’s no easy feat by any means, given the time of year that some of this culling is taking place,” he said.

Farmers sourcing new herds will also have to understand the history of the herd, including getting M. bovis records of tests from the autumn, which should be part of sale agreements.

“Herds get bought and sold each year,” he said. “In the context of the greater industry it is manageable, but the laws of supply and demand, when there are not many herds for sale, will drive the market — not just stock prices but the availability as well,” he said.

There is a stand-down period of 60 days for infected farms after they have been depopulated, during which time farms are cleaned and disinfected.

Getting herds back to their former size and quality will take time for some.

“In many circumstances, generations of breeding programmes have been wiped out through the culling programme.

“So as well as the production implications there is the emotional toll that farmers are going through,” Mr Reid said. “Getting a herd of the same quality could take a considerable period of time.”

Mr Reid said getting rid of existing herds will be testing for farmers.

“Seeing good quality stock loaded on to a truck will be a pretty traumatic experience,” he said.

Cows can be milked at two years of age, and the typical lifespan of a dairy cow varies from 6-10 years.

Rabobank dairy analyst Emma Higgins said the cull could see “regionalised inflation” for replacement stock in hard-hit infected areas.

For most farmers, the season officially ends today. It will be two months before new season production resumes.

Prime Minister Jacinda Ardern this week announced that the Government and farming sector leaders had agreed to try to eradicate the cattle disease Mycoplasma bovis from New Zealand to protect the national herd and the long-term productivity of the farming sector. She said the country had “one shot” at getting rid of the disease, which causes painful, untreatable illness in cattle.

The decision to eradicate was taken collectively by Government and farming sector bodies after months of intense modelling and analysis.

There has also been a very real human cost. Until Wednesday, May 23 former Van Leeuwen Dairy Group (VLDG) sharemilkers Sarel and Mary Potgieter were living in a leaking caravan in Australia, reported the Otago Daily Times.

They had been forced to sell anything they could, including household items, to pay debts, and both were now taking anti-depressants, Mrs Potgieter said.

They also had the “heartbreaking” sight of watching the cattle in their charge dispatched for slaughter, including pet cows.

“On the last day, myself and Sarel could not face it. But the worst was the newborn calves that MPI (Ministry for Primary Industries) instructed pet foods to shoot and slit their throats,” Mrs Potgieter said. She believed the Government and MPI should leave decision-making concerning the disease response to farmers, as it could be “controlled easily”. — Additional reporting by Otago Daily Times

“We had it under control within a month and kept on top of it till all the cows were culled,” she said.

The couple were variable lower-order sharemilkers in Morven. The animals and farm belonged to VLDG but the six staff, machinery and vehicles were the couple’s responsibility.

    Do you support the call for a feasibility study into developing an "inland port" and sending the district's export logs to Napier Port by rail, to get log trucks out of the city and to repurpose the port and harbour area?
