A pilot trial seeking to identify a possible link between the methane cows produce and their genetics has got underway in the Waikato.
The trial involving dairy breeding bulls is believed to be a world-first and is being run by Livestock Improvement Corporation (LIC) and CRV which together sire 90% of the New Zealand dairy herd through their artificial breeding bulls. The project has received funding from the New Zealand Agricultural Greenhouse Gas Research Centre (NZAGGRC).
