MS Biotec is pioneering the use of the rumen-native bacteria Mega e ® (Megasphaera elsdenii) to support rumen health in feedlot cattle, cows, and calves at key moments of transition and stress.

MS Biotec and its affiliates are the world’s only commercial providers of Mega e, and the company is a co-owner of the patent for a superior strain of this prolific lactic acid-utilizing bacteria (Megasphaera elsdenii NCIMB 41125).

Lactipro Innovations

Convenient, Easy to Use and Stable for Months

Lactipro® harnesses the power of Mega e, a superior lactic acid utilizer, to enable beef and dairy producers to support healthy rumen pH and improve profitability. MS Biotec offers two Lactipro product lines with shelf life of months instead of days.

We Pioneered the Science of Rumen Health

In 1993, scientists researching the unique properties of the rumen-native bacteria Megasphaera elsdenii identified a superior strain, NCIMB 41125. MS Biotec built on this research to pioneer the science of rumen health and anaerobic fermentation. We collaborate with leading universities, nutritionists and veterinarians to validate every product we bring to market. Our state-of-the-art labs are the only facilities in the world with the anaerobic processes required to produce viable Mega e on a commercial scale for use in cattle.

We’ve been using Lactipro for the last five years. From our Lactipro research, what we saw was a significant reduction in the time it takes to get cattle back up on feed following terminal processing.

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 feedyard with 10,000 head down to the guy who feeds 500 head.

Dr. Brian Dorcey


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.
