Disease pressure and antibiotic dependence challenge livestock and aquaculture Disease pressure, pollution of the farming environment and a continued dependence on antibiotics are placing significant strain on the livestock and aquaculture sector. Overuse of antibiotics in particular raises concerns around resistance, product safety and long-term sustainability. Vietnam Food Joint Stock Company (VNF) approaches this challenge by drawing on biological materials rather than conventional chemistry, aiming for a solution that controls pathogens while easing the pressure to rely on antibiotics. This is the goal behind Kito-Sil, its nano chitosan silver complex. Vietnam Food Joint Stock Company (VNF) combines chitosan and silver ions in one nano complex Kito-Sil is a nano chitosan silver complex that pairs the biological activity of chitosan with the antibacterial action of silver ions. Its key specifications are:  Chitosan content ≥ 10,000 ppm and silver ≥ 1,000 ppm  Particle size ≤ 150 nm, increasing the contact area and interaction with microorganisms The positive surface charge on the nano particles helps Kito-Sil approach, inhibit and kill many types of disease-causing microorganisms. Silver ions dispersed within the chitosan matrix create a synergistic effect that increases antibacterial activity, conductivity and overall efficacy. Through this design, VNF aims to deliver strong pathogen control from a biological base. A green solution across aquaculture and livestock farming In aquaculture, Kito-Sil supports the control of pathogens such as Vibrio parahaemolyticus, Vibrio harveyi and Aeromonas salmonicida, helping reduce pathogens in the water, strengthen immunity, support growth and limit odour from accumulated organic matter. In livestock farming, it helps partially replace antibiotics, clean the barn environment, deodorise and control cross-infection among animals. By offering a safe, effective, environmentally friendly and cost-competitive option, Kito-Sil helps reduce antibiotic pressure and improve sustainable production. As the livestock and aquaculture sector moves toward greener practices, the nano chitosan silver complex from Vietnam Food Joint Stock Company (VNF) points to how biological materials can support animal health while lowering reliance on antibiotics.
