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.

All of our animal products are Safe Feed-Safe Food Program certifiedThe SafeFeed-Safe Food Program is a third party certification program to promote feed and food safety for the care and growth of animals. and FAMI-QS certified FAMI-QS is the worldwide Quality and Feed Safety Management System for the sector of Specialty Feed Ingredients.   under third-party certification. This means you can be assured we are producing a variety of safe, wholesome and effective animal nutritional supplements, crop preservatives and plant biostimulants.

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: 


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


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


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


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
