Understanding methane supplements

The ‘Carbon Neutral Grazier Network’ provides the latest tips and information on positioning your business to take advantage of the rapidly evolving world of environmental markets and certification schemes.

Supplements that inhibit methane production are an integral component of our pathway to carbon neutrality, but as an emerging technology many of us know very little about them. Now that some key options have reached the point of commercialisation in Australia, it is important that we begin to understand what they are all about, are they safe to use and how might they fit into livestock production systems.

In this webinar recording, the network was proud to host Ms Ainslie Macdonald (Research Fellow – University of Melbourne) when she discussed the efficiency, safety, cost, and impacts of two leading methane mitigation options:

  • Bovaer®
  • Asparagopsis

Listen to Ainslie in this webinar recording to expand your knowledge and understanding of these methane supplements.
