He has given over 70 invited presentations and published over 170 books, book chapters, and peer-reviewed journal articles.

Webinar Overview:

Dr. Hristov will give a general overview of livestock emissions in the US, talk about criteria products claiming enteric methane mitigation effect should meet, summarize what has been tested, what works and what doesn't, and talk about future directions.

How should products be tested for enteric methane mitigating effect?

What works and what doesn't.
