Effect of Nano-hydroxyapatite as an Alternative to Inorganic Dicalcium Phosphate on Growth Performance, Carcass Traits, and Calcium and Phosphorus Metabolism of Broiler Chickens

The influence of nano-hydroxyapatite (NHA) as a source of calcium (Ca) and phosphorous (P) alternative to inorganic dicalcium phosphate (DCP) on the performance, carcass traits, and the Ca and P contents in serum, bone, and excreta was evaluated in broiler chickens. One-day-old un-sexed Arbor Acres Plus broiler chickens (n.= 160) were randomly assigned to four treatment groups of four replicates with 10 birds in each replicate.
