Enteric methane mitigation strategies through manipulation of feeding systems for ruminant production in Southern Australia
This project has identified and quantified feed supplements, grain treatments and novel forages that enable improved strategies for enhancing milk and meat production while simultaneously reducing methane intensity and possibly greenhouse gas emissions. The knowledge generated from this project will be invaluable to the Australian dairy and livestock industries and dairy and livestock farmers in the temperate zone of Australia will benefit in the long term. Policy experts will have information to enable improved inventory techniques for estimating methane emissions.
Refinements to methodologies (both in vitro and in vivo) have resulted in greater confidence in the data being generated from more cost effective scientific techniques, which in turn will provide greater opportunity for other research groups (nationally and internationally) to utilise such methods and screen other feed options.
Research on the commonly fed supplement wheat, has raised the possibility of using this supplement at different feeding rates to significantly reduce methane emissions and intensity from dairy cows. However, based on data from this project it is suggested that further research be undertaken to further elucidate the mechanisms behind such reductions and in particular the influence of wheat type (starch and protein content) and forage structure (short and long chop length).
