Nano-technology is an emerging technology with tremendous potential and diverse applications in human health, agriculture, and animal nutrition. It also offers potential advantages in supporting research in many areas of life sciences. Nano-technology has many vital biological applications as living systems depend on many nano-scale objects like proteins, DNA, and enzymes. Trace minerals are normally used in very minute quantity in animal nutrition but issues like lower bioavailability, antagonism, and higher excretion rates from body limit their efficiency. Nano-technology offers opportunity to mediate these issues as nano-particles possess different physical and chemical properties than other forms of minerals. Nano-particles possess higher physical activity and chemical neutrality. Bioavailability can be enhanced by increasing the surface area of respective minerals by making their nano-particles. Owing to potential advantages of nano-particles, interest in exploring their potential use and efficacy in animal production has increased significantly in this decade. Although limited literature is available regarding potential effects of nano-particles in poultry nutrition, still some convincing evidences have suggested the feeding of trace minerals (zinc, copper, silver, selenium, iron, chromium, and manganese) in the diets of broilers, layers, turkeys, quails, etc. Excellent antimicrobial activities of nano-particles of Ag, Cu, and Zn, against key poultry pathogens like Salmonella and Campylobacter, indicate their potential for effective use in poultry production. Recent studies have also demonstrated modulation of gut health by nano-particle through increasing abundance of beneficial microbes (Lactobacillus and Faecalibacterium) and production of short-chain fatty acids. This review aims to provide insights on absorption, metabolism, and distribution of nano-minerals in the body. Moreover, potential applications and various aspects of using nano-trace minerals in different poultry species with potential effects on performance and health of birds are discussed.
