ISSUE FOCUS 40 FEED & ADDITIVE MAGAZINE April 2023 About Dr. Clarisse Techer Clarisse Techer obtains a Msc degree in Microbiology at the Rennes 1 University (Fr) in 2009. After this period, she worked on the impact of dietary fiber in piglet feed and on the establishment of sensitive and specific immunological methods for the detection of staphylococcal enterotoxins in dairy products. In 2012, she joined the Animal nutrition and processing domain of the Avril group (Fr) and undertakes PhD research in the joint research unit “Science and Technology of Milk and Egg” between Agrocampus Ouest and the National Research Institute for Agriculture, Food and Environment (INRAE). Her PhD work concerned the control of spoiling bacteria in refrigerated food composed of egg products. Since 2015, she works in the Department of Research, Innovation and Development (RID) of MiXscience (Avril group) as researcher in microbiology and then as RID manager. Her main current research interests include animal gut health management, search for alternative solutions to the use of antibiotics in animal feed and mycotoxin risk management. About Anne-Laure Tournay Graduated with an Agricultural Engineering Master’s degree, Anne-Laure Tournay has a solid experience in marketing acquired within various international agricultural companies. She started working as a product manager for the world's leading equipment manufacturer for dairy farming, responsible for the Cow Comfort range for the Southern European market. From 2016, she held the position of international product manager for a veterinary laboratory, in charge of the Hygiene range for all animal species. She joined MiXscience in September 2019 as In Feed Solution Product Manager. She is in charge of the development and marketing of two solutions portfolios: the Rabbit range, and the Multiprotect range dedicated to issues related to biotoxins. aspartate aminotransferase levels at D21 (Figure 4), indicating a better liver health. The improvement of performance and a significant decrease of mortality (Figure 5) has equally been demonstrated in a duck commercial farm in Vietnam. The trial was performed with a total of 23 440 animals, divided in 2 groups and receiving for 46 days, naturally challenged local feed containing with DON and T2 Toxin at levels of 0.5 mg/Kg and 39 µg/Kg, respectively. CONCLUSION With growing evidence, there is no more doubt that the presence of mycotoxins is practically unavoidable in feed and that its management remains key because of significant threat to animal health, productivity and sanitary issues that can occur. The complementary effects resulting from the association of ingredients specifically selected to face these various animal challenges, make it possible to combine multiple modes of action in the gut and in the global organism such as mycotoxins adsorption, biodegradation and animal bioprotection, and contribute to better animal health, well-being and performance.
