Nanobiotechnology is a growing field in animal and veterinary sciences for various practical applications including diagnostic, therapeutic, and nutritional applications. Recently, nanoforms or nanoparticles (NP) of essential minerals have been explored for growth performance, feed utilization, and health status of animals. Various mineral NP, such as calcium, zinc, copper, selenium, and chromium, have been studied in different farm animals including poultry. Because mineral NP are smaller in size, and show different chemical and physical properties, they are usually absorbed in greater amounts from gastrointestinal tract and exert enhanced biological effects in the target tissues of animals. In various studies, mineral NP have been comparatively studied relating to its larger inorganic and organic particles in poultry. There are contradictory findings among the studies on comparative improvement of production performance and other mineral functions perhaps due to different sizes, shapes, and properties of NP, and interactions of minerals present in basal diets. There are not many studies correlating physical and chemical properties of mineral NP and their biological functions in the body. Nonetheless, it appears that mineral NP have potential for their uses as mineral supplements in preference to inorganic mineral supplements for their better absorption avoiding antagonistic interactions with other minerals, growth performance, and physiological functions, especially at lower doses compared with the doses that are recommended for their larger particles. Supplementation of mineral NP in diets could be a promising option in the future. This review summarizes the studies of different essential mineral NP used as mineral supplements for feed intake, growth performance, egg production and quality, and blood variables in poultry.
