My undergraduate thesis focused on "Studies on Early Weaning Methods in Pigs." At that time, antibiotics were used. Since then, I have conducted research on alternatives to antibiotics using various nutritional supplements, which eventually led me to plant-derived tannins. Currently, I am studying the use of tannins to control pathogens, viruses, coccidia, and roundworms.
