Studies on Utilization of Calcium Phosphate Nano Particles as Source of Phosphorus in Broilers

Abstract

Calcium phosphate nanoparticles (NCP) for the experiment were prepared by wet chemical method. Commercial (BV 400) day old broiler chicks (n=192) were distributed randomly in seven dietary treatments. T1: Control (dicalcium phosphate-100%) (DCP), T2: 75% DCP+25% NCP, T3: 25% NCP, T4: 50% DCP+50% NCP, T5: 50% NCP, T6: 75% NCP+25% DCP, T7: 75% NCP, T8: 100% NCP. The experiment continued in two phases: starter phase-0-4 weeks and finisher phase-5-6 weeks of age. Weekly body weight and feed consumption were recorded. At 6th week, serum biochemical parameters and carcass traits of the experimental birds were determined. The size of NCP was found to be 51nm to 200nm. The average body weight gain of broiler birds at the end of 6th week of age were 1460.2±33.7, 1470.8±17.5, 1367.4±24.8, 1466.5±27.9, 1490.2±34.4, 1444.8±25.4, 1441.0±25.2 and 1394.3±24.9g in the group of T1, T2, T3, T4, T5, T6, T7 and T8, respectively. Significantly (P 0.05). The carcass characteristics and studied biochemical parameters of the broiler birds under different dietary treatments did not differ significantly (P>0.05). The growth performance of the birds was better at NCP 50% level either as sole source or in combination with DCP, the FCR remained unchanged among treatment groups, indicate that the ideal level of incorporation of NCP could be 50% in broiler ration.
