Nano phosphorus on egg production and quality in Japanese quail

Supplementation of nano form of mineral increases bio-availability and efficiency of utilization. In this regard, an experiment was performed to study the effects of calcium phosphate nano particle (NCP) supplementation with or without combination with DCP (Dicalcium Phosphate) on the performance of Japanese quail birds. NCP was synthesized in the laboratory and the particle size was determined by using scanning electron microscope. NCP size was found in the range of 51- 200 nm. For performance study, 192 Japanese Quail birds divided into 8 groups viz, T1-Control DCP 100%, T2- 25%NCP+ 75% DCP, T3- 25% NCP, T4-50% NCP, T5- 50% DCP + 50% NCP, T6- 75% NCP, T7- 75% NCP + 25% D.C.P., T8- 100% NCP. Performance of egg production was carried out for 100days after onset of laying. Total hen housed egg production percent ranges from 38.142±2.285 (T4) to 2.428±0.286 (T8). Shape index of the eggs ranges from 89.992±2.871 (T7) to 76.023±0.043 (T3). The average weight (g) of the eggs ranges from 11.982±0.185 (T4) to 6.022±0.123 (T8). Shell thickness of the eggs (mm) ranges from 0.172±0.007 (T4) to 0.12±0 (T8). The Haugh unit of the eggs ranges from 85.512±0.540 (T4) to 79.095±0.655 (T5).There are significant differences in the above mentioned egg quality parameters among different dietary treatment groups. Considering the above results of the present study, it may be concluded that dietary NCP at 50% level supplementation with 50% DCP have better bioavailability with higher production indices in Japanese quail birds. Significantly higher differences (p>o.o5) were achieved in case of egg production parameters and egg quality traits. In other wards supplementation of NCP at 100% level had adverse effects on growth, and seriously altering egg quality and other parameters.
