Feed and pet food systems stand at a decisive crossroads. Climate pressure, resource constraints, regulatory evolution, and shifting market expectations are reshaping how protein and lipid sources are evaluated and implemented. This volume delivers a structured and interdisciplinary assessment of novel ingredientsâincluding insects, algae, agricultural by-products, microbial- and plant-derived sources âacross livestock, aquaculture, and companion animal nutrition. It addresses nutritional performance, oxidative stability, functional properties, regulatory pathways, sustainability trade-offs, and market dynamics. By integrating scientific evidence, decision-modelling approaches, and industry case studies, the book enables readers to translate innovation into robust, economically viable, and environmentally responsible solutions.
Dr Cristina Murcia holds a PhD in Chemistry (University of Bonn, Germany) and is currently Senior Technical Service Manager at Kemin Pet Food and Rendering. She specialized in feed and pet food systems, applying fundamental science to ingredient stability, shelf life, food safety, and sustainable industrial practice.
