INTERVIEW 66 FEED & ADDITIVE MAGAZINE April 2025 Thomas Pecqueur, Anti Mycotoxin Agent Technology Lead at Cargill: “Mycotoxins have profound and detrimental effects on the intestinal microbiota of poultry. One of the primary effects of mycotoxins, particularly deoxynivalenol (DON), is that they slow down the maturation of the intestinal microbiota. This delayed maturation can have far-reaching consequences, as a mature and stable microbiota is essential for strong health and optimal performance.” The intestinal microbiota plays a crucial role in poultry performance and productivity. By measuring and assessing it, poultry producers can gain a significant advantage, ensuring their flocks perform optimally. Importantly, understanding the microbiota can reveal one of the most significant hidden risks to health and performance: Mycotoxins. We had the pleasure of speaking with Thomas Pecqueur, MHS Technology Lead at Cargill Animal Nutrition and Health. He shared his insights on the importance of the poultry gut microbiome and the scientific findings on the effects of mycotoxins on poultry. Mr. Pecqueur also discussed the use of anti-mycotoxin agents and provided recommendations for poultry producers to effectively manage these risks. The details are in our interview. Let's start with the microbiome. Can you explain the role of the intestinal microbiota in poultry, and why it is important for poultry health and performance? The intestinal microbiota refers to the complex community of microorganisms that live in the poultry gut. This ecosystem consists primarily of bacteria, but also includes fungi, viruses, and protozoa, collectively forming a diverse and dynamic population that performs several critical functions. The importance of the microbiota cannot be overstated. Firstly, the microbiota helps break down complex nutrients, making them more accessible for the bird's metabolism and aiding in nutrient digestion and absorption. They also produce beneficial metabolites like short-chain fatty acids. These processes enhance feed efficiency and contribute to better growth rates. Secondly, a healthy and balanced gut microbiota is integral to the immune system of poultry. POULTRY GUT HEALTH AND PERFORMANCE: THE MYCOTOXIN CHALLENGE
