Feed grade tannic acid can promote animal growth, improve the utilization of nutrients, anti-bacteria and fungus.

Description

Tannic acid has various effects such as antibacterial and anti-diarrhea, and can regulate nitrogen metabolism, methane release, and fatty acid metabolism in ruminants, and has the functions of optimizing feed structure and improving feed utilization in ruminants.

Applications

Tannic acid is a kind of polyphenolic compound, which widely exists in plants and has various biological activities such as antibacterial, antiparasitic, antiviral, antioxidative, anti-inflammatory, and immune regulation. Therefore, tannic acid is the main research direction of natural substitutes for antibiotics in feed. Plant tannic acid has a strong protein affinity and has been successfully used in ruminant nutrition to reduce the degradation of rumen protein, thereby improving protein utilization and animal production efficiency. Adding tannic acid-containing feed to ruminant diets also has three important functions, namely, controlling animal flatulence, intestinal parasites and pathogenic bacteria. Tannin has traditionally been considered an "anti-nutritional factor" in monogastric animals and poultry, but recent studies have shown that tannin, when properly applied, improves the gut microbial ecosystem and enhances gut health, thereby increasing production performance. The suitability of plant tannins as a substitute for antibiotics in feed depends on a number of factors that contribute to the large variability in their observed effects.
