CRV Ambreed receives government funding for further genetic research

An investment of $8.4 million will be put towards the seven-year research project that reduces nitrogen leaching

CRV Ambreed’s genetic discovery that led to the launch of LowN Sires this year around reducing nitrogen leaching, has been the cornerstone of a successful bid to receive government research funding, announced by Research Science and Innovation Minister Dr Megan Woods.


The Ministry of Business, Innovation and Employment (MBIE) fund will invest $8.4 million towards the seven-year research project. The project will be led by DairyNZ and co-funders CRV Ambreed and Fonterra. It will also involve researchers from DairyNZ, Abacus Bio, A. L. Rae Centre for Genetics and Animal Breeding, AgResearch and Lincoln University.

The $21 million project will be made up of the government’s $8.4 million contribution, with $11.5 received from farmers via Dairy NZ’s levy, and the balance coming from CRV Ambreed and Fonterra.

The project

It’s based on breeding dairy cows with lower levels of nitrogen in their urine, urea nitrogen being one of the nutrients impacting water quality. The use of the nitrogen-lowering trait to reduce nitrogen leaching was recognised by CRV Ambreed’s research scientist Phil Beatson. CRV Ambreed is already providing farmers with semen from bulls under its LowN Sires brand.

LowN Sires bulls are desirable for traditional traits as well as being genetically superior for the trait milk urea nitrogen (MUN). MUN is a measure of the amount of nitrogen contained as milk urea. CRV Ambreed has found overwhelming international evidence of a direct connection between MUN and the amount of nitrogen excreted in urine.

Beatson says that cows bred for lower levels of MUN are expected to excrete less nitrogen in their urine which will, in turn, reduce the amount of nitrogen leached from grazed pasture. Daughters of CRV Ambreed’s 2017 LowN Sires are set to send New Zealand towards saving 10 million kilograms in nitrogen leaching a year -based on the national herd number of 6.5 million dairy cattle.

The large-scale research will involve thousands of cows on farms around the country to test the effectiveness of breeding and measure the reduction of nitrogen leaching expected through genetic selection – potentially up to a 20 percent reduction.

CRV Ambreed Managing Director Angus Haslett says many farmers are already on the journey towards greener cows through buying straws this year from LowN Sires bulls, and confirmation of the major research project is very welcome.

"This is excellent news for the industry and the environment, and we congratulate the minister and our partners for seeing the importance of this research to New Zealand."

He says farmers are already working hard to mitigate nitrogen leaching and meet environmental compliance levels. "The beauty about the genetic approach is its potential to have a significant additive effect to other strategies a farmer might be taking to reduce nitrogen leaching with minimal cost and disruption to their current farm management systems."

The research announcement has been welcomed by DairyNZ Strategy and Investment Leader for Productivity, Dr Bruce Thorrold, who says the project is of major importance in dairy’s drive to lower its environmental footprint.

"Better options to reduce nitrogen levels in our food farming gives choices for our rural communities in that they can achieve environmental gains and maintain local businesses – it’s very much a win-win."
