The supplementation of mineral in nano form increases bioavailability and efficiency of utilisation. In this context an experiment was carried out to study the effect of calcium phosphate nanoparticles supplementation on the growth performance of broilers with the objective to reduce the quantity of mineral supplementation that would intern reduce the feed cost. Since phosphorus is expensive among the mineral sources, its requirement as dicalcium phosphate was replaced by nano form of calcium phosphate as low as 50% requirement to 100 % at 10 % increment range. Calcium phosphate nanoparticles were synthesised in laboratory by wet chemical method and the particle size and morphology were determined using transmission electron microscope. Calcium phosphate nanoparticles ranged between 20 and 90 nm. Feeding trail was conducted using mash feed. Feeding trial in 70 male broiler chicks (Cobb 400) from day 1 to 28 indicated that the cumulative feed intake was significantly (p<0.05) higher (1487.30 ± 19.99, 1510.80 ± 13.82, 1549.30 ± 5.75, 1550.00 ± 3.52, 1562.50 ± 3.85 and 1572.80 ± 1.50 g ) in birds fed with calcium phosphate nanoparticles at 50, 60, 70, 80, 90 and 100 % respectively in the diet than control diet containing coarse particles of dicalcium phosphate (1466.60 ± 4.73 g). By the end of fourth week, birds fed with 50 % and 60 % calcium phosphate nanoparticles had significantly (p<0.05) higher bodyweight gain (1069.90 ± 9.31 and 1068.50 ± 36.51) respectively than control (891.60 ± 48.1 g). Birds fed with 50 % calcium phosphate nanoparticles recorded best feed conversion ratio (1.39 ± 0.02) and it differed significantly (p<0.05) from control (1.64 ± 0.08) group. It is concluded that supplementation of 50 % of calcium phosphate nanoparticles can be practiced instead of the conventional practice of dicalcium phosphate incorporation in broilers diet. Thus, it is postulated that the usefulness of nano form in reducing the mineral quantity to half in the diet will reduce the cost of feeding when the actual production of calcium phosphate nanoparticles is up scaled to an industrial level.Keywords

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.- Assessment of Calcium Phosphate Nanoparticles as Safe Mineral Supplement for Broiler Chicken
