VANNIX C

VANNIX C – Tannic Acid for Intestinal Health and Pathogen Control

VANNIX C is a proprietary formulation of tannic acid and a direct-fed microbial designed to improve poultry intestinal health and performance efficiency. By combining the unique benefits of tannic acid – a natural plant extract – and probiotics, VANNIX C helps minimize factors that can challenge intestinal integrity, thereby allowing birds to reach their performance potential.

Features and Benefits

  • Proprietary hydrolysable tannic acid extract with enhanced bioactivity
  • Reduces oxidative stress and inflammation in the intestine
  • Supports intestinal barrier integrity and animal performance
  • Tannic acid reduces coccidiosis lesion scores and oocysts counts1
  • Helps coccidiosis-vaccinated poultry maintain performance1,2
  • Bacillus coagulans direct-fed microbial supports intestinal microflora balance

 

Tannic acid molecule structure

What is Tannic Acid?

Tannins are plant-derived polyphenolic compounds, which are classified by their structure into two groups: hydrolysable tannins and condensed tannins. Condensed tannins are found in sorghum and are typically considered anti-nutritive for poultry. In contrast, hydrolysable tannins – like the tannic acid found in VANNIX C – are produced as a part of the plant defensive response to environmental or pathogen challenge. Research has shown that tannic acid may provide benefits to intestinal health through antioxidant, anti-inflammatory and astringent activities.3 Additionally, tannic acid has known anti-parasitic activity4 and has been shown in research to inhibit growth of several common poultry pathogens.5,6 With these multiple activities, one intriguing application of tannic acid could be as a solution for coccidiosis.7

VANNIX C – Plant Extract and Probiotic in One

VANNIX C combines the functional benefits of natural plant extracts and active microbial ingredients to provide producers with a cost-effective solution to support poultry intestinal integrity and overall performance. During the development of VANNIX C, numerous plant extracts and direct-fed microbial combinations were evaluated in order to formulate an optimal mixture to support overall health and performance. The resulting formula has consistently been shown to reduce coccidiosis lesion scores, lower oocyst counts and improve broiler performance.1 VANNIX C has been shown to support coccidiosis-vaccinated birds maintain performance.1

Tannic Acid Extract

The tannic acid used in VANNIX C is a natural extract from gallnuts (60-70% hydrolysable tannins). The tannic acid is further processed into a proprietary blend of tannic acid – referred to as tannic acid extract – with enhanced bioactivity towards pathogens. Tannic acid extract has been shown to reduce the viability of Eimeria sporozoites in vitro (Figure 1) as well as to decrease intestinal lesions and Eimeria oocyst shedding during a coccidiosis challenge.1 The observed reduction in Eimeria challenge may be related to direct action of tannic acid extract against the Eimeria parasite5,6,8 or through antioxidant, anti-inflammatory and astringent activities which support intestinal health.

Bacillus coagulans

Bacillus coagulans is a unique, spore-forming microorganism that supports intestinal microflora balance in livestock and poultry. Unlike other Bacillus organisms, Bacillus coagulans produces lactic acid and acetic acids, which may provide antimicrobial benefits.9 Research has shown Bacillus coagulans can positively influence innate immunity.10,11
