How Does Megasphaera elsdenii work?

On traditional step-up diets, naturally-occurring Megasphaera elsdenii in the rumen of cattle takes three weeks or more to reach population levels required by the animal to effectively handle high-concentrate diets.

As cattle transition to higher-concentrate feed, lactic acid may accumulate in the rumen if Megasphaera levels are not sufficient.

  • If lactic acid builds up, the rumen’s natural pH balance can become too acidic and health issues can result — from acidosis to rumen damage to weight loss, bloating and more.
  • Megasphaera elsdenii metabolizes lactic acid, converting it to less acidic short-chain fatty acids that provide nutrition to the animal and enable better regulation of rumen pH.

    Details & Apply
  • "Megasphaera elsdenii is the most powerful tool for nutritionists and operators."

    Dr. Jane LeedleMicrobiologist
  • "If I can use Lactipro to take the nutrition stress out of changing that diet, that has been where I’ve seen Lactipro working on a feed yard with 10,000 head down to the guy who feeds 500 head."

    Dr. Brian DorceyDVM
  • "Lactipro allows us to get cattle on finish feed ten days sooner. Cattle on feed for 110 days show like 120-day cattle, that’s why we identify them with a Lactipro ear tag. I always sell these cattle first."
