Novonesis launches Europe’s first Bacillus probiotic for dairy cows

COPENHAGEN, Denmark. April 29, 2026. Margins are under increasing pressure in dairy farming, and every drop matters. Efficient nutrition is key to a healthy herd, and with feed prices making up 60-70% of the total cost of milk production, ensuring the proper feed formulation has never been more relevant.

To support healthy and productive herds and sustainable farming operations, Novonesis recently launched Bovacillus™, a feed-stable and versatile Bacillus probiotic to improve health and productivity in dairy cattle. 

“Dairy farmers are often faced with the choice between health or productivity and profitability or sustainability. However, with Bovacillus™, farmers don’t have to choose – they can get productive and healthy cows along with a profitable and sustainable business,” says Kim Mueller Christensen, Vice President of Global Marketing for Animal Biosolutions.

Bovacillus™ delivers consistently superior results for dairy farmers by dual action: it works both in the rumen and the intestines, supporting gut barrier and a healthy immunity against potentially harmful bacteria. This means that energy extracted from the feed converts into milk instead of being used to fight off bad bacteria in the gut. Further, it improves fiber digestibility and enhances feed efficiency, in turn supporting better productivity and more sustainable farming, as more energy can be extracted from the same amount of feed.

The results speak for themselves: Bovacillus™ delivers one more kilogram of milk per cow per day, resulting in 37 grams extra protein, 31 grams extra fat and 44 grams of extra lactose per cow per day.  

“Adding Bovacillus™ made my life easier, and we definitely see the difference with calmer, healthier cows and more milk volume”, says Craig Jopp, a dairy farmer. 

Bovacillus™ comes in a highly resilient, heat-stable form that can be applied across virtually all feed types, providing reliability under variable conditions. It provides a feed-stable, easy, and effective biosolution that works every day, in every feed. And while it has just launched in the EU, the product is supported by 5 years of real-world experience and over approximately 1,500,000 happy consumers.

3 key facts about Bovacillus™:

• Bovacillus™ delivers 3.7% more feed efficiency from the same amount of feed.
• This dual-strain probiotic can withstand temperatures of up to 95 °C in application and therefore applied in both liquid and dry feed (pellets, premixes, mineral blocks, licks, TMR and mash feed).
• Efficacy of Bovacillus™ has been scientifically proven in 9 peer-reviewed publications and 12 peer-reviewed mode of action studies.
