In the modern livestock and poultry breeding industry, animal health and production efficiency are the top concerns of breeders. In recent years, against the backdrop of the ban and restriction on antibiotics as well as zinc limitation, the development of novel feed additives has attracted growing attention across the livestock breeding sector. As a new type of feed additive, zinc tannate (TAZ, short for Tannic Acid-Chelated Zinc) has garnered widespread attention for its potential as a safe, efficient and eco-friendly feed additive.
