The weaning period is critical in piglet development, marked by a weakened immune system that makes piglets susceptible to E. coli F4 infections. This bacterium disrupts the intestinal lining, causing severe diarrhea, which hinders nutrient absorption and slows growth, often leading to high mortality rates. While antibiotics and zinc oxide have helped manage these infections, stricter regulations drive the need for alternatives. Polyphenols from agro-industrial by-products are promising due to their antimicrobial, anti-inflammatory, and antioxidant properties. This study investigates the in vitro antimicrobial effects of polyphenol extracts from mustard seed meal against E. coli. Extracts were derived from both unfermented and S. cerevisiae-fermented mustard seed meal to assess fermentation’s impact on antimicrobial activity. Over 24 hours, bacterial growth was monitored in varying polyphenol concentrations, with significant antimicrobial effects observed from both extracts. These findings highlight mustard seed meal’s potential as an alternative to antibiotics and zinc oxide in piglet farming, promoting a sustainable, circular economy.
