Livestock vaccination to curb greenhouse gas emissions

A vaccine has been produced which aims to curb greenhouse gas emissions from Australia's livestock.

The livestock industry is Australia's second largest source of Greenhouse Gas Emissions.

Scientists at CSIRO Perth have been working for three years to produce a vaccine which alters the organisms in an animals stomach.

Spokesman Rob Kelly says the aim is to stop livestock emitting methane gases, which contribute to global warming.

"We estimate that if we can get widespread adoption of this technology that we should be able to reduce total greenhouse gas emissions from Australia by the order of 3 per cent or so," he said.

Sheep and cattle producers across the nation are being asked to take part in trials of the vaccine.
