Nanotechnology, defined as manipulation of matter at the nano scale (1–100 nm), has emerged as a transformative tool in animal production and enhancement of meat quality. Nanotechnology has shown great promise in tackling key challenges in the livestock sector. This chapter discusses the application of nanotechnology in improving animal health, enhancing meat quality. Nanoparticles, characterized by their high surface area-to-volume ratio and unique physicochemical properties, are increasingly employed in precision nutrition through nanoformulated feed additives, targeted nutrient delivery systems, and encapsulated bioactives. These contribute in improving meat characteristics such as texture, flavor, and color while reducing the reliance on conventional additives. Furthermore, nanocoatings and nanoemulsions extend the shelf life of meat products with their potent antimicrobial activity against foodborne pathogens, including resistant strains, and support advanced packaging technologies, real-time monitoring via nanosensors. By integrating nanotechnology into animal production, processing, and packaging systems, the industry achieves superior product quality, improved safety, and sustainable production practices by minimizing input costs, and delivering high-quality meat products that meet evolving consumer expectations.
