Culbac® Probiotic Plus™ Animal Products: Exceptional Feed Additives that Drive Results and Protect Your Livestock and Animals

Animals that perform poorly or get sick can cost you and your operation a lot of money. Animals with healthy immune system, however, can thrive, meet their genetic potential, and provide maximum return on your investment.

Culbac® animal products are produced to optimize gut health and support the immune system in animals with safe, proven and cost-effective additives.

Not all animal digestive systems work the same. Culbac animal products are specifically formulated to meet the unique digestive and nutritional needs of livestock. Over the past 60 plus years, university research and field studies have demonstrated time and time again that Culbac products are effective, reliable, and safe in animals including dairy cows, beef cattle, sheep, goats, poultry, swine, horses, and other species.

Culbac animal health and nutritional products include a unique Culbac® Probiotic Plus™ is a proprietary beneficial bacterial fermentation product that has undergone a special processing and is enhanced and stabilized to support the growth of good bacteria and minimize pathogens that can negatively impact your soil, plants or animals. Additional vitamins, minerals and amino acids are added to the formulations for extra benefit.  fermentation process that begins with our proprietary strain of bacteria.

Why is this important?

Culbac®  feed additives are more advanced than probiotics and prebiotics because they are derived from a unique fermentation process that includes nutrient additives, anaerobic and aerobic phases that promote and optimize vitamin-complexing, biopeptides, glycopeptide generation, and enzymatic efficiency which is what animals need. The resulting fermentate plus optimized and stabilized bacteria is the base for the Culbac® Probiotic Plus™ formulation.

In other words, adding Culbac products to animal feed provides not only a nutritional boost but also selective biopeptides and components to support the activation, defense, and preparedness of the immune system in an all-in-one easy-to-use concentrated product.

Unlike probiotics or prebiotics, all Culbac animal products provide nutrients and metabolites which feed the native, species-specific, beneficial microflora already present in the animal gut. Feed components and feed quality differ depending on your location and your animal’s digestive system needs to adapt both geographically and seasonally.

Culbac products help manage the transitions and the general stresses animals face including:

  • Heat Stress
  • Cold Stress
  • Transportation Stress
  • Gestational Stress
  • Performance Stress
  • Production Stress


Culbac products are shelf-stable, do not require refrigeration, are cost-effective and provide support in general situations or when the digestive system is exposed to antibiotics or medications (natural or synthetic).

Studies with Culbac® Probiotic Plus™ Animal Products have shown:

  • Gut pH
  • Native microflora populations
  • The linking and communication of the epithelial wall
  • Dilation of blood vessels
  • Robust responses to vaccines

Why are Culbac Animal products easier, safe and more economical to use? They:

Are compatible with medication programs including deworming, vaccination, antibiotic treatment, etc.

Are all-natural and environmentally friendly (lower methane emissions, sustainable efficient feed-to-gain)

Are shelf-stable – don’t require special storage or refrigeration

Provide a concentrated delivery resulting in higher ROI

Are available in liquid and dry formulas

Can be formulated in pellet feeds

Have no withdrawal period

How do Culbac Animal Products work?

When incorporated into feed Culbac animal products travel through the entire digestive tract of an animal with a concentrated formula of vitamins, minerals and nutrients as well as protected stabilized bacteria. When these bacterial bodies reach the animals’ gut enzymes release bioactive ingredients which stimulate the growth of the beneficial bacteria existing in the gut and prevent bad bacteria from colonizing. Additional bioactive ingredients dilate blood vessels, support responsiveness to stressors, support reproductive efficiency, and provide other physiological support.

Also, the animal’s immune system is stimulated when the cell wall of our product and the non-viable cpgDNA are released. As a result, the animal’s immune system gets primed and is ready for a faster and more effective response to stress or pathogens (bad bacteria).

In head-to-head studies, Culbac Animal products have been shown to outpace competitors resulting in more robust gut bacteria and higher ROI.
