Part 2: Megasphaera elsdenii & Milk Fat Depression: pH, Silage Inoculants, and Rumen Bacterial Community Composition – Dr. Paul J. Weimer

June 2, 2017

pH, Silage Inoculants, and Rumen Bacterial Community Composition 

Check out this next segment from Dr. Paul J. Weimer, from the U.S. Dairy Forage Research Center, as he dives into his second segment of a four part series on Megasphaera elsdenii & Milk Fat Depression: A good bug gone bad. This is an evolving story, that will hopefully lead us to a solution that is a significant economic problem for the dairy industry.

What you will learn:

• Do cows having different ruminal pH profiles have different microbial communities?
• How strong are the correlations between milk fat depression and the presence of megasphaera elsdenii in the rumen?
