A review on the effect of ZnO nanomaterial as supplement in poultry farming

Abstract

Zinc (Zn) is listed as second most essential micronutrient in animal body which is required to control growth, immunity, wound restoration, metabolism, etc. Since, the animal body doesn't have any mechanism to store Zn, it has to be regulated by proper dietary intake. Therefore, Zn has been introduced into the food source of poultry farming as organic and inorganic means for the betterment of the growth and development. The use of nano sized ZnO with in 100 nm increases the mineral absorption and utilization considerably due to its attractive properties such as high surface area to volume ratio. Due to the higher bioavailability of zinc oxide nanomaterials, the quantity of zinc oxide nanomaterials required for supplementation in poultry feed is less compared to that of bulk zinc. The zinc oxide nanomaterial supplementation improves the immune response. Zinc oxide nanomaterial serves as an antioxidant and increases the fertility and productivity of chicken. This review addresses the significant role played by zinc oxide nanomaterial as a supplement on the growth productivity of chicken.
