Minerals constitute a major role in production, reproduction and health of animals. Their deficiency or imbalances in diet lead to reduced growth and production. Nano minerals are mineral particles that exist in nano size (1-100 nm). Their action is attributed to their small size and increased surface area, thus leading to greater bioavailability. They are synthesized by physical, chemical or biological methods. Biological synthesis of Se nano-particle is gaining popularity due to its easily available source and less toxicity. Nano Zn particles could possibly reduce microbes generating methane in anaerobic fermentation. Thus, they reduced methane release and increased microbial biomass production. Sodium selenite nanoparticles were encapsulated by nano-precipitation for controlled release of Se nanoparticles. The release of selenium from nanoparticles was higher in acid (pH < 4), that caused better availability of the mineral in the small intestine.
