Since our founding in 2010, MS Biotec has pioneered the use of the rumen-native bacteria Mega e® to enable regulation of rumen pH and to stimulate a healthy rumen environment.

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).

Our signature line of Lactipro® products harness the power of Mega e to enable beef and dairy producers to support healthy rumen pH and improve profitability. We invented anaerobic processes and packaging to ensure each Lactipro application maintains maximum potency from production to delivery. Our state-of-the-art labs and production lines are the only facilities in the world that can produce viable Mega e for cattle on a commercial scale.

A History of Innovation

The history of MS Biotec is a story of innovation and persistence — from early research into rumen health, to founding the company in 2010 to bring Mega e to scale, to breakthroughs in freeze-drying that enabled the 2020 launch of LactiproFLX and LactiproNXT.

Our founder and CEO Leander van der Walt first learned of Megasphaera elsdenii in his home country of South Africa in 2003. Recognizing the potential of the rumen-native bacteria to support animal health and diet transitions, the South African team patented the most effective strain of Mega e evaluated (Megasphaera elsdenii NCIMB 41125). A U.S. patent, FDA use approval and advances in anaerobic processes and packaging followed, culminating in the founding of MS Biotec and the first commercial application at a U.S. feedyard in 2010.

Since then, MS Biotec has continued to pioneer the science — evolving Lactipro products, expanding its team, and innovating anaerobic processes and packaging at its state-of-the-art R&D and production facility in Wamego, Kansas.
