AgResearch testing of genetically modified High Metabolisable Energy (HME)
ryegrass shows that it can grow up to 50% faster than conventional ryegrass,
and has the ability to store more energy for optimum animal growth, to be
more resistant to drought, and to produce up to 23% less methane (the
largest single contributor to New Zealand's greehous gas emissions) from
livestock.

The research is funded by the New Zealand Government and industry partners
including DairyNZ. Modelling also projects that adoption of GM ryegrass
could lead to less nitrogen excreted into the environment by animals feeding
on the ryegrass, thus less nitrate leaching and lower emissions of nitrous
oxide, another greenhouse gas.

The initial growing trial of two months was held last year, confirming the
suitability of conditions for the growth of the GM plant. Full growing trial
of five months is currently underway. If these trials become successful, the
researchers will apply for animal feed trials which may be conducted in two
years' time.
