WATCH: Waikato farmer's impassioned defence of his fellow farmers following an expose on the "dark side of the farming industry".

MPI says an investigation into the alleged mistreatment of bobby calves had begun before news broke.

Investigator whose shocking video exposes cruelty in New Zealand's dairy industry says he was tipped off by concerned farmers.

Fonterra, Federated Farmers, the Ministry for Primary Industries and the Government need to take urgent action to stop cruelty in the dairy industry, writes Catriona MacLennan.

International dairy prices are at a "particularly bad" part of the cycle, but are expected to improve substantially in the first half of next year.

The August-September price bubble has popped, according to a dairy broker.

In 2014/15, dairy companies processed 21.3 billion litres of milk containing 1.89 billion kilograms of milksolids.

There's some good news from the dairy sector today, with Fonterra saying its financial performance is improving.

Consumer and food service came in at $408 million, up 216 per cent on the previous year's.

New Zealand has about 720,000ha of land under irrigation, but about half that again could be sustainably irrigated by 2025, an industry body says.

Any chance of an upgrade in Fonterra's farmer payout became more remote today after a big drop in world dairy prices.

Farmers might have to pay for their emissions like everyone else under a revision of the Government's main climate change policy.

Silver Fern Farms shareholders have voted strongly in favour of a 50/50 joint venture with China's Shanghai Maling Aquarius

Food researchers have been granted $10.9 million under a new Government scheme designed to encourage scientific brilliance and boost exports.

Silver Fern Farms chairman Rob Hewett said the board remained convinced that a joint venture proposal from Shanghai Maling Aquarius was the best choice.

State owned farmer Landcorp says it supports an alternative recapitalisation plan for the giant meat company.

A group of Silver Fern Farms shareholders who oppose the company's proposed joint venture with Shanghai Maling Aquarius say their offer of a $90 million alternative capital raising proposal remains a live issue just days before the deal goes to the vote.

Beef exports have hit $3 billion - a record high, driven by international shortages, rising local production, and a falling New Zealand dollar, Statistics NZ said.

Maling's proposal to acquire 50% of Silver Fern Farms reaffirms that Chinese investors are interested in New Zealand's rural and food-based assets.

Fonterra is reporting a big turnaround in annual profit and a much improved forecast cash payout for the current year.

Canterbury dairy company Synlait Milk has almost halved its net profit for the July year to $10.6 million.

Low dairy prices have continued to weigh heavily on farmer sentiment, according to Rabobank's Rural Confidence Survey.

Chief executive Theo Spierings says dairy giant has to make tough decisions as review increases job cuts to 750.

The blocking of a sale of Lochinver Farm will be welcomed by those with a narrow, not to say xenophobic, view of the national interest.

Does this morning's big jump in world dairy prices mean an increased payout for farmers? There might be a long way to go.

Prices are expected to rise at this week's GlobalDairyTrade auction but doubts remain as to how much further improvement is in store.

Fonterra is cutting back the amount of product it sells on its GlobalDairyTrade auction platform for the next 12 months.

Pre-tax profits for an average sheep and beef farm in New Zealand will increase to $109,900 this season - 9.6 per cent more than last season, but 3.1 per cent below the five-year average, Beef and Lamb New Zealand says in its 2016/6 season outlook.

Deal would increase dominance of New Zealand's biggest meat exporter but erode farmer control of the industry.
