Breeding cows with reduced environment impact

category Low N Sires

Widespread use of genetics for low-N dairy cows could result in reduction of Nitrogen leaching of 20% in 20 years. CRV Ambreed head geneticist, Phil Beatson, explains what breeding for low milk urea nitrogen and low-N output means for the dairy industry.

It’s a strategy that could change your dairy future. Lincoln University’s recently-published research is the first independent work carried out in New Zealand on pasture-based grazing systems to report that cows with lower Milk Urea Nitrogen (MUN) breeding values have lower concentration of N in their urine and urin…

Lincoln Research supports LowN Sires

category Low N Sires

CRV Ambreed welcomes the release of research findings from Lincoln University, which demonstrate that breeding dairy cows with low Milk Urea Nitrogen (MUN) can reduce the amount of nitrogen they excrete in their urine.

CRV Head Geneticist Phil Beatson says the findings are timely following the release of changes to the Government’s Essential Freshwater regulations last week, part of which focuses on improving farming practices to reduce nitrogen loss.

“The findings of Lincoln’s research confirm that genetics are an important and easily implemented solution for fa…

Patient converters set for low N future

The Jarmans have been adaptable farmers for more than 150 years – and they’re still innovating.

Paul and Ann Jarman run Essendon, a 400ha dairy farm at Greendale, central Canterbury.

Supplying Westland Milk Products, Essendon is milking 860 cross-bred cows and includes a fully self-contained block for wintering and growing out young stock. About two thirds of the 400ha is milking platform.

The Jarmans are connected to Stage 2 of the Central Plains Water (CPW), a high-pressure, piped irrigation scheme covering much of central Canterbury.

Sustainability and m…

Next generation of environmentally friendly calves born

category Genetics, Low N Sires

The next generation of environmentally friendly calves has been born around the country as Kiwi dairy farmers continue their efforts to reduce their nitrogen output.

Hundreds of thousands of calves have been bred from CRV Ambreed’s LowN™ Sires since the company launched the product in 2016. For the 2018 season, over a quarter of all CRV’s orders were for from LowN™ sires.

With the latest LowN™ progeny now being reared, hundreds of farmers are well on their way to building a herd of cows that excretes less nitrogen (N) in their urine.

CRV has identified and pro…

More dairy farmers breeding to reduce environmental footprint

Dairy farmers are uping their game and doing more to improve their environmental footprint through their breeding programme.

CRV Ambreed’s Product Manager Peter van Elzakker says more farmers have been asking about CRV Ambreed’s LowN sires this year with the goal to start breeding for lower Milk Urea Nitrogen concentration (MUN).

Cows bred for lower levels of MUN are expected to excrete less nitrogen in their urine, which then reduces the amount of nitrogen leached when cows are grazed on pasture.

This year over a quarter of all CRV Ambreed’s orders are for bu…
