ABSTRACT
Nanotechnology is revolutionizing the scientific world and is offering solutions to numerous scientific problems, including animal feed-related issues. Manipulation of matter at the nanoscale opens up possibilities for improving the functionality of feed nutrient molecules for the benefit of livestock health and production. Nanotechnologies have the potential to improve nutrient availability and act as novel vehicles for nutrient delivery, as well as serve as a tool to enable further elucidation of nutrient metabolism in animal physiology. Mineral particles as feed additives can pass through the intestinal wall and into animal body cells more quickly in the nano-form than ordinary bulk minerals with larger particle size and thus improve bioavailability. Nanoparticles of trace minerals such as iron, zinc, selenium and copper, when given to animals in appropriate quantity, promote growth, act as antibacterial agents, and modulate immune response and reproductive behaviors. Nanofeed has immense potential in aquaculture and seafood industries. In this chapter, the effect of different nano-feeds to different animals has been discussed. The other side of the coin, the adverse effects of the use and/or abuse of nano-feed supplements in animal feeds have not been ignored. Finally, the need to step up and redouble efforts in research to fully tap the potentials of nano-materials and nanotechnology for the overall benefits and advancement in animal health and production has been suggested.
