Developing biotechnology to reduce cattle methane emissions

Scientists from the Department of Agriculture and Fisheries and University of Queensland are developing a new way to reduce methane emissions in cattle.

The $7.5 million project aims to develop controlled-release biopolymer technology that delivers a continuous low dose of methane-reducing bioactive to cattle rumens.

This will be particularly useful in extensive grazing systems, where supplements are normally delivered through licks, with little or no control of intake by individual animals.

The project is co-funded by Meat and Livestock Australia and the MLA Donor Company.

How will it work?

The project aims to produce biopolymer devices that slowly release active agents (such as 3-NOP) into the rumen over an extended timeframe. These can be tailored to suit cattle of various ages (from calves to adults).

Join our expert panel

A volunteer expert panel is being formed to ensure the rumen inserts are practical for on-farm use.

The panel, which will include six producers from a range of enterprises, will meet online at least once a year.

If you’d like to volunteer for the panel, please complete the expression of interest form by 31 March 2023.
