NEWS 10 FEED & ADDITIVE MAGAZINE November 2025 A new study, unveiled by Aker ǪRILL Company, found that including ǪRILL Aqua in low fishmeal diets helps Atlantic salmon maintain growth, nutrient utilization, and fillet quality, while reducing the need for plant proteins and synthetic additives. Conducted by researchers from the Atlantic Veterinary College (UPEI), Dalhousie University, and Aker ǪRILL Company, the trial also found that higher krill meal inclusion improved the visual appearance of wounds after healing, a potential benefit for harvest quality and market value. As today’s salmon feeds are mainly plant-based with small inclusion of marine ingredients to address resource sustainability, farmers face challenges such as reduced palatability, nutrient imbalances, and increased reliance on synthetic supplements. Mark D. Fast, PhD, Professor at the University of Prince Edward Island, states, “Our findings show that higher inclusion of ǪRILL Aqua in low-fishmeal diets preserves fish growth and nutrient use — but importantly also leads to reduced scarring and improved gross appurtenance of wounds, which helps to improve fillet quality and reduces economic losses for producers” Kiranpreet Kaur, Director RCD, Aker ǪRILL Company, adds, “This research shows that ǪRILL Aqua can maintain high fish performance in plant-based diets, low fish meal. It’s a functional ingredient that delivers both nutritional and environmental benefits.” Read more>> New study shows krill meal enhances salmon growth Photo: Andrei Armiagov | Shutterstock Edward Manchester, Global Commercial Director of Ecolex Animal Nutrition, delivered a compelling presentation on “Nutritional Interventions to Reduce Antimicrobial Resistance (AMR)” at the Vietstock 2025 AMR Forum on October 9, 2025. He emphasized that the AMR crisis is intensified by the absence of new antibiotic classes, with no discoveries made since 1984, only modifications of existing compounds. Manchester advocated for integrating nutritional interventions into a feed strategy as part of a comprehensive and integrated One Health approach that also includes biosecurity and hygiene, and good farm management practices aligned with Vietnam’s National Action Plan on AMR. The selection of alternatives to antibiotics should consider specific gut health challenges, farm management systems, economics and regulatory requirements. According to Manchester, just some of the nutritional interventions to enhance gut health and reduce AMR include: Mitigating Mycotoxins, Reducing Pathogen Load and Increasing Digestion, Maximizing Nutrient Absorption, Novel Antibacterials, and Medium Chain Fatty Acids (MCFAs). Manchester concluded that ensuring a sustainable future for animal agriculture requires strong industry collaboration. This includes uniting farmers, veterinarians, nutritionists, feed millers, and feed additive suppliers under a comprehensive One Health approach. By working together across disciplines and sectors, stakeholders can implement integrated strategies that combine nutritional interventions with biosecurity, hygiene, and good farm management practices. Such collective action is essential to effectively reduce antimicrobial resistance, safeguard animal and public health, and support resilient and productive livestock systems.
