ISSUE FOCUS FEED & ADDITIVE MAGAZINE April 2023 47 About Dr. Swamy Haladi Dr. Haladi is the commercial and technical manager for the Mycotoxin Risk Management Programme of Selko Feed Additives. He obtained his Bachelor and Master degrees in veterinary science in India, and then moved to Canada to obtain his PhD in animal and poultry science. During his studies and career, he continued to gain more interest and knowledge in the area of mycotoxins, especially the global challenges around this topic. He published various articles in both peer-reviewed journals as well as industry magazines and he truly understand the global challenge of mycotoxins. He also developed practical limits for mycotoxins in various species. About Avinash Bhat Avinash Bhat has been working for Nutreco and Masterlab since 2017 and has over 20 years of experience in laboratory management and customer service laboratory activities. Currently, he lives in the Netherlands where he works as technical specialist, responsible for mycotoxin analysis at Masterlab. example, the presence of AF, fumonisins and OTA can damage the liver and kidneys and interfere with immune system function, while ZEA interrupts the reproductive system. T2/HT2 toxins and DON damage the gut and immune system functions. All the mycotoxins cannot be managed with the same mitigation strategy. For example, AF respond well to binding agents, while Fumonisins and DON, don’t bond well to agents added to feeds. Mitigation tools must contain multiple modes of action such as a means to reduce the bioavailability of mycotoxins, and ingredients capable of enhancing immunity, gut health, and antioxidant status of animals. CONCLUSIONS Undoubtedly corn is the major raw material used in feeds to meet the nutrient demands of livestock and poultry. Despite the efforts from animal scientists and industry professionals, it has not been possible to find a cost-effective alternative to corn. Due to the changing agricultural practices and climate change, mycotoxin contamination in corn is steadily increasing. On top of this, more and more mycotoxins are held responsible for their negative effects on subtle parameters such as gut health, immunity, and antioxidant status. If the future mycotoxin regulations are based on such subtle parameters, mycotoxin limits in animal feeds must come down further. This will certainly put pressure on acceptable limits of mycotoxins in corn. Innovations are needed to improve the overall resilience of animals against a broad range of multiple mycotoxins.
