An experiment was carried out with the objective of determining the bioavailability of calcium phosphate nanoparticles by supplementing calcium phosphate nanoparticles at graded levels from 50 to 100% of phosphorus content to the standard source (Dicalcium phosphate - coarse particle) at 10 per cent increment. Tibial bone morphometry, bone and serum mineral profile and carcass characters in broiler chicken were studied with mash form of feed in 70 male broiler chicks (Cobb 400) from day 1 to 28 indicated that the there was no significant variation in the parameters studied. The tibial bone ash, calcium and phosphorus content are unison for both the control and 50% calcium phosphate nanoparticles supplemented groups. The results indicated that the bioavailability of phosphorus in calcium phosphate nanoparticles was 200 per cent when compared to dicalcium phosphate. This finding may help the poultry managers to minimize the feed transport cost and also minimize the mineral wastages.
