This book examines the biological foundations of animal production and highlights how nutrition, feed resources, and management practices influence the productivity and health of livestock and aquaculture systems. It explores the relationship between biological processes and the efficient utilisation of feed materials in animal production, demonstrating how appropriate nutritional strategies support growth, reproduction, and overall physiological performance. The discussion considers both conventional and alternative feed resources, explaining their role in improving feed efficiency and supporting sustainable animal production systems. Particular attention is given to the biological and environmental factors that influence feed quality, digestion, and nutrient utilisation in different animal species. The book also addresses the importance of maintaining food safety and quality within animal production systems, recognising the direct connection between feed management and the safety of animal-derived food products. Through an integrated scientific perspective, the text illustrates how biological understanding contributes to responsible livestock and aquaculture development.

The book encourages a deeper appreciation of the biological principles underlying modern animal production. It supports advanced academic study in animal science, nutrition, aquaculture, and agricultural development, promoting sustainable approaches to feeding systems and livestock productivity.
