The Dairy Nutrition Blackbelt Podcast

In this special re-run episode of The Dairy Nutrition Blackbelt Podcast, we bring back our conversation with Dr. Mutian Niu, Assistant Professor at ETH Zurich, who explains exhalomics, an approach for assessing rumen fermentation by analyzing volatile organic compounds in cattle breath. He discusses how this technique can provide valuable insights into rumen function and help improve cattle health monitoring, with potential applications in managing methane emissions and optimizing dairy production. Listen now on all major platforms!

"We’re using exhalomics to study the volatile compounds in cattle breath, which provides new insights into ruminant metabolism and health monitoring."

Meet the guest: Dr. Mutian Niu is an Assistant Professor of Animal Nutrition at ETH Zürich, focusing on ruminant nutrition, precision livestock farming, and data science to improve sustainability. He earned his PhD in Animal Sciences and a Master’s in Statistics from UC Davis, with research on methane emissions and rumen metabolism.
