Education 🎓

Valentin Menoury’s academic journey spans leading European institutions. He began at ESA, École Supérieure des Agricultures d’Angers (2016 – 2020), earning an Agricultural Engineering degree in Animal Science 🎓🌾. He then completed an MSc in Animal Sciences—Animal Nutrition & Metabolism at Wageningen University & Research (2019 – 2022), graduating cum laude 🥇🐄. Currently, he is pursuing a PhD in Animal Sciences at Université Clermont Auvergne (2022 – 2025), investigating biobased solvents for dairy cow nutrition 🔬🥛. This robust educational foundation underpins his expertise and demonstrates his commitment to advancing sustainable livestock nutrition and environmental stewardship 🌍🌿.

Experience 💼

Valentin Menoury is currently a PhD student at INRAe (UMR Herbivores), where he is leading research on sustainable agriculture 🌱. His project focuses on replacing hexane, a toxic solvent used in oilseed processing, with 2-methyloxolane, a biobased alternative, aiming to enhance dairy cow nutrition 🐄🥛. Valentin has also contributed to animal nutrition research during his time as a Master’s student at Wageningen University & Research 🏫, where he graduated cum laude. His work bridges environmental sustainability with animal science, advancing both animal health and milk quality 🌿💧.

Research Focus 🔬

Valentin Menoury’s research focuses on sustainable agriculture and dairy science 🌱🐄. He pioneers the replacement of hexane with 2-methyloxolane to produce defatted oilseed meals, studying their impact on dairy cow nutrition, digestibility, and welfare 🥛🔬. His work evaluates feed formulation, fermentation metrics, and milk quality parameters such as fatty acid profile and residue levels 📊🧪. Through controlled feeding trials and advanced statistical analyses, he ensures safe, high-quality dairy products while reducing environmental and health risks 🌍🛡️. Collaborating with international experts, he seeks to optimize feed rations and milk composition, driving innovation in sustainable dairy production 🚀. He drives future innovation.

Contributions 🚀

Mr. Menoury’s contributions center on replacing petroleum‑derived hexane with biobased 2‑methyloxolane for soybean meal defatting 🌱. He conducted controlled feeding trials in dairy cows, using analytical methods and collaboration with WUR statisticians, demonstrating the first detection of n‑hexane residues in milk from hexane‑defatted meals 🥛⚠️. This pioneering work underlines potential health risks and supports regulatory reevaluation by EFSA, ECHA, and BAuA in the EU 🇪🇺. By assessing feed digestibility and nutritional profiles, he established 2‑methyloxolane as an effective, safe alternative 🔬✔️. His findings promise to transform oilseed processing, enhance food safety, and advance sustainable agriculture with reduced environmental impact 🌾🚀.
