Nothing magical in healthy happy cows

Written by

NEW ZEALAND farmer Rex Butterworth follows a simple philosophy: keeping his cows happy and healthy.

“They pay you back ten-fold, it’s really a no-brainer,” says Butterworth who farms at Waikato on New Zealand’s north island.

A top-performing dairy farm, Butterworth’s figures speak for themselves. In the 2014-15 season, Rex and his wife Sharon milked 480 cows at peak, versus Waikato’s average of 459 and its top-10% average of 479.

Milksolids per cow on the Butterworth farm were 492kgMS, versus Waikato’s average of 394 and Waikato’s top-10% average of 444. Milksolids per milking hectare were 2237kgMS, versus only 1317 for Waikato and 1645 for the region’s top 10% of farmers.

Total revenue for the Butterworths was just over NZ$1 million versus NZ$831,000 for Waikato and NZ$977,000 average for the top 10%.

It’s not surprising Butterworth scooped the Waikato title in the Dairy Business of the Year competition; he also finished runner-up in the national competition.

Hosting about 120 farmers and stakeholders at a field day on his farm in Winton, Butterworth says he doesn’t do anything special on his 113ha property (106ha eff).

“All we do is feed cows and grow grass; please don’t go away from here thinking anything special happens on this farm.”

But Butterworth refers to one major decision that was a turning point for his farm: in 2012 he erected two Herd Homes, each holding 250 cows. He made this decision after realising he was not always succeeding in his quest to farm healthy, happy cows; but the Herd Homes changed that.

It’s ventilation system and shade sails lower the temperature during summer, reducing cows’ heat stress, resulting in the cows consuming at least an extra 8kgDM/cow daily, raising profits and improving cow condition.

Butterworth also noted that their water consumption rose by nearly 50% during the hottest time of the day.

He says the warm, dry environment in winter led to mastitis at calving time halving from 10% of newly calved cows to 5%.

“We put this down to the cows being stood off in a less stressful, cleaner, dry environment.

“The clear roof allows sunlight through, killing light sensitive bacteria and drying the floor. Maintaining a dry floor plays a big part in Herd Home management.”

Butterworth says the Herd Homes mean lactation length is not as heavily influenced by cow condition, pasture cover or weather.

Animal welfare remains a high priority for the Butterworth.

“With the Herd Homes we focus on prevention, not cure and maintenance and not repair.”

He is intent on the basics – pasture management, making high ME supplements, fully grown young stock, cow condition and the transition of cows from pre- to post-calving.

“Get those things right and the rest is easy.”

Cows are fed pasture, maize silage, grass silage and PKE; all supplements are fed in the Herd Homes. All house effluent is exported off-farm to the maize ground and silage paddocks at the run-off farm.

“Growing a high yielding, high ME maize crop is essential to our system. The difference in cost between a 22tDM and 26tDM crop is minimal but the economic gain/loss is huge.”

Environment is also a key point but Butterworth admits he has not always been as environmentally aware as he is now. Like many he once saw effluent as a problem and costly to get rid off; today it’s a valuable resource.

He says as an operator of an intensive dairy farm with the potential to be a major polluter, he had to demonstrate that he could operate responsibly. The Herd Homes help make the farm more environmentally sustainable.

“The farm has a far lower environmental footprint than most conventionally run dairy farms and is well below the industry average; this proves more profit need not mean more pollution.”

People power

Butterworths only employ people they respect and like.

They want employees to share their vision and successes.

Farm managers Vernon Madeley and Barbara Fell are long-time employees.

“Their contribution has been outstanding and we couldn’t be happier with their efforts,” says Butterworth.

“They should be – and have every right to be – proud of what they have helped us achieve.”

While the industry makes headlines, the market turns

We're getting close to the peak of the production season in southern Australia, in one of the most tumultuous periods in the recent history of the industry. In the past 18 months, an unprecedented volume of milk has moved between major dairy companies in a short space of time, and most likely has some way to go yet, as the aftershocks of the major step-down in milk prices towards the end of the 2015-16 season continue to reverberate.

Northern NSW grass factory

UP ON the Northern Rivers of NSW – the top, eastern corner that abuts Queensland and the Gold Coast – they reckon Cory Crosthwaite is far and away the best grass grower around.

The Tweedside dairy’s 94ha, all sandy loam river flats apart from 8ha of red volcanic ‘hill’, produces more than 20,000kg of dry matter/ha a year, while pastures on your average dairy farm in the region do around 3500kgDM/ha/year. 

Effluent on pasture returns nutrients

THE RE-USE of second pond effluent back onto pasture will help return valuable nutrients to the soil, a six-year study has found.

The study at the DemoDAIRY research and demonstration farm at Terang tested a range of application rates of second pond effluent to pasture to determine how much can be safely applied.

It recommended that correct use of second pond effluent should be encouraged on dairy farms but found applying too much on the same land could have negative environmental impacts.

Fighting kikuyu invasion

Victor Rodwell, who milks 840 Holstein Friesians and crossbreds on a dairy platform of 250ha at Boyanup, 200km south of Perth, plans to sow more AberMagic high sugar ryegrass this autumn for its persistent and dense tiller and root growth, as well as its high nutritional value.

Change your rhythm to make lasting changes

I WAS recently informed that over 90% of what we do and how we do it is out of habit or routine and very little is spontaneous or based on the information on hand at the time.

Initially I wanted to challenge this suggestion but found that it is true in my life.

Summer rain can herald problems for livestock

THE VICTORIAN Department of Primary Industries (DPI) is advising livestock producers that while the recent rain could provide valuable green feed, they need to keep close watch on their stock to avoid possible health problems.

MANY FARM tracks are in need of serious maintenance after the wet conditions prevalent across most of Australia last year. Following are some practical tips that will hopefully help save time and money when the season permits some repair work.


The Stony Rises, near Colac, are aptly named.  While the soil is rich with nutrients and the rainfall consistently good, the land is disrupted by a vast number of basalt rocks caused by volcanic activity from thousands of years ago.

During the past month, I have received many calls regarding employment – the majority seeking clarification from people on whether they are employing or being employed correctly.
