Better understanding the rumen for sheep.
Ruminant methane emissions are a product of microbial fermentation. The host animal influences microbial populations by feed choice and through morphological / functional variation in its fore-stomachs. There is evidence that these are heritable through the host. The overall objective of this project is to measure methane emissions on sheep from selection lines at different ages on different diets and use the measurement and the samples taken to better understand the link between the host genome, rumen physiology and the microbial genome in the rumen.
What are we doing?
This work will underpin discovery of new tools to breed low methane emitting sheep, permitting the Australian sheep industry to participate in the Carbon Farming Initiative.
