Wamego, KS – MS Biotec announces the launch of LactiproNXT with Mega e, an innovation built on seven years of research and development. LactiproNXT enables beef and dairy producers to maintain digestive health in feedlot cattle, cows and calves, and to improve profitability.
LactiproNXT places a large number of rumen-native bacteria (Megasphaera elsdenii NCIMB 41125) directly into the rumen where it immediately begins targeting lactic acid. Lactic acid can build up and have dangerous effects on cattle as they transition to higher-energy diets or experience stress.
“MS Biotec scientists have been researching the unique properties of Mega e since our founding in 2010,” says CEO Leander van der Walt. “As we celebrate our 10th anniversary, we are excited to bring this innovative new product to market.”
LactiproNXT is an easy-to-use drench for feedlot cattle, cows, and calves and comes in 2 package sizes: 200 mL and 1,000 mL pouches. Each pouch contains freeze-dried bacteria separated from the rehydrant by a seal and features a clear bottom gusset that allows users to see inside the pouch.
“LactiproNXT gives beef and dairy producers an effective way to maintain rumen health and to increase productivity,” van der Walt explains. “Our scientists took our original drench with a 2-week shelf life to the next level to produce this low volume drench containing viable anaerobic bacteria with stability for months.”
MS Biotec Q&A
MS Biotec is pioneering the use of the rumen-native bacteria Mega e to manage diet transitions while maintaining animal health. Our signature line of Lactipro products harness the power of Megasphaera elsdenii NCIMB 41125, a superior strain of lactic acid-utilizing bacteria. Our PhD-led teams collaborate with leading universities and researchers to advance the science of rumen health and validate every product we bring to market. 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 Megasphaera elsdenii NCIMB 41125.
What is LactiproNXT?
LactiproNXT is an easy-to-use drench that can be used for feedlot cattle, cows, and calves. LactiproNXT comes in 2 package sizes: 200 mL and 1,000 mL pouches. Each pouch contains freeze-dried bacteria, Mega e, separated from the rehydrant by a seal and features a clear bottom gusset that allows users to see inside the pouch. LactiproNXT places a large number of viable Mega e into the rumen to support healthy rumen function. MS Biotec selected this superior strain because of its high growth rate in the rumen, its ability to grow at low pH, and its prolific utilization of lactic acid.
What is Mega e?
Mega e (Megasphaera elsdenii) is a rumen-native bacteria cattle rely on to digest high-energy diets. A naturally occurring anaerobic bacteria, Mega e has unique properties that make it essential to rumen health. While other rumen microorganisms consume amino acids and simple sugars first, Mega e prefers lactic acid as its energy source. As Mega e targets lactic acid in the rumen, it produces beneficial volatile fatty acids, such as butyric and propionic acids. Mega e is the primary and most prolific lactic acid utilizer. It contributes to the development and maintenance of a healthy rumen and enables pH regulation.
How does Mega e work?
With traditional feed transitions, naturally occurring Megasphaera elsdenii in the rumen takes weeks to reach populations required to effectively handle grain-based diets. As animals transition to higher-concentrate feed, lactic acid may accumulate in the rumen if Megasphaera elsdenii levels are not sufficient to handle the increased acidity. 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, weight loss to bloating, and even death. As the primary and most prolific lactic acid utilizer, Mega e works to improve rumen health, supports a healthy pH, and contributes to the growth of rumen papillae, which absorb nutrients.
How does MS Biotec produce and package LactiproNXT?
Our state-of-the-art production facility in Wamego, Kansas, uses proprietary anaerobic production processes and packaging that enable us to freeze-dry Mega e in a live, suspended state. LactiproNXT offer a months-long shelf life from manufacturing date when stored in refrigeration, and can be used for feedlot cattle, dairy and beef cows, and calves.
