VANNIX C4 – Phytogenics and Probiotics to Knock Out Poultry Gut Health Challenges

VANNIX C4 is a proprietary blend of tannic acid extract, phytogenic molecules, beta glucans and a probiotic (Bacillus subtilis  PB6) used to minimize the impact of enteric challenges on poultry performance. 

With more than 50% of commercial poultry raised without antibiotics today, producers need novel solutions that fit in their management systems to help support poultry health and performance. As a phytogenic additive, VANNIX C4 serves as a natural, cost-effective antibiotic alternative to help reduce the impact of pathogens – like Eimeria  and Clostridium perfringens – on poultry intestinal integrity, thereby allowing poultry to achieve their full performance potential. Research has shown that VANNIX C4 can be used not only in conventional programs, but also in combination with coccidiosis vaccination programs to help poultry maintain performance without impacting immunity development.1,2

Features and Benefits

  • Tannic acid extract – a novel phytogenic ingredient to support intestinal barrier integrity
  • Beta glucans to prime the immune system to respond to pathogen challenges
  • Phytogenic molecules from oregano and yucca for antimicrobial and antioxidant qualities
  • Bacillus subtilis PB6 – a natural probiotic for maintenance of a healthy and balanced intestinal microflora
  • Reduces intestinal lesions due to coccidiosis1,2 and necrotic enteritis3
  • Helps coccidiosis-vaccinated poultry maintain performance1,2,3

Phytogenic Feed Additives – Not All Are Created Equal

Phytogenics are natural, bioactive molecules from plants such as tannins, essential oils, saponins or flavonoids. Conventional phytogenic feed additives (PFAs) often contain ingredients sourced from dried plant materials or extracted plant essential oils which, because of natural variation among plants, can result in variable levels of active molecules in the PFA. This variation may impact the efficacy and consistency of the PFA under field conditions.4

VANNIX C4 differs from conventional PFAs because it not only contains both phytogenic and probiotic ingredients but also because the ingredients and active molecule levels are standardized during manufacturing of the final product. This process helps to ensure that VANNIX C4 will provide consistent responses for your operation.

VANNIX C4 – Four Levels of Protection for Gut Health

VANNIX C4 combines the functional activities of natural plant extracts, immune supporting beta glucans and active microbial ingredients to provide producers with a cost-effective solution to support poultry intestinal integrity and overall performance. Because of its unique formulation, VANNIX C4 offers four levels of protection to support intestinal health of poultry.

Suggested Feeding Rates

  • Broilers and Layers: Mix 0.5 lbs per ton of finished or complete feed
  • Turkeys: Mix 0.75 lbs per ton of finished or complete feed

Four Benefits of Tannins for Poultry Gut Health


Poultry producers know a healthy gut is critical for optimal performance. Unfortunately, managing enteric challenges – like coccidiosis and necrotic enteritis – in antibiotic-free production systems is anything but easy. To protect poultry from disease, using feed additives – like tannins – that offer a wide-range of potential benefits for optimal gut health is key.
