These can be shaped as spheres rods or spirals depending on the species. They can be used to promote health (probiotic) or can be pathogenic (illness – causing bad bacteria) fermentation products are proven in the field and by university research to be safe, effective, reliable and trusted.

Culbac  Products are not a probiotic, they're better! 

While our products have similarities to prebiotics Prebiotics are compounds in food that induce the growth or activity of beneficial microorganisms such as bacteria and fungi.   and probiotics Probiotics are live bacteria and yeasts that are good for you, especially your digestive system.   which use live bacteria, Culbac products use stabilized bacteria Preserved, non-viable bacteria that still maintain physiological relevance to a host. . Our proprietary bacteria have undergone a special fermentation process and then are stimulated and stabilized. The resulting product provides nutrients and metabolites which feed the native, species-specific, beneficial microflora already present in the animal gut as well as in plants, forage and soil.

  What is Culbac® Probiotic Plus™

 It is unique, proprietary beneficial bacteria that have undergone a special fermentation and are 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. 

 All Culbac products include specialized bacterial fermentation processes to enhance nutrient bioavailability and have been stabilized for a long shelf life.  

What are some key advantages of Culbac® Probiotic Plus™ vs. a Prebiotic or Probiotic?

 While there are numerous advantages to using our proprietary bacteria and unique fermentation process, here are four major benefits: 

activity

Our products stimulate native bacteria instead of introducing alien bacteria, therefore they are safer and more effective

durability

Our products are not harmed by high temperatures or chemicals used in feed processing so they are easy to integrate into your standard farming practices

stability

Our products have longer shelf lives and don’t require refrigeration so they are easier to work with and more economical

versatility

Many of our products are not species-specific therefore you can use them in a variety of applications versus competitor products which often require specialized products for every application or usage
