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?
Rather read than watch?

What's next?

Keep an eye out for more from Dr. Weimer as he continues his series exploring the effects of rumen microbes on milk fat synthesis. His upcoming segments will cover ruminal dosing to establish if M. elsdenii is a causative agent of MFD and lastly a summary of experiments and future direction.
