Abstract:
Zinc oxide nanoparticles were synthesized and characterized using by UV-Visible Spectroscopy (UV-Vis); Scanning Electron Microscope (SEM); Energy Dispersive X–Ray Spectroscopy (EDAX); X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). Six feeds were prepared by using the differential quantities of Zinc oxide nanoparticles such as 0;20; 40; 60; 80 and 100 mg along with a fish meal; groundnut oil cake; wheat flour and tapioca flour. Feed utilization and haematological parameters of zebrafish were estimated after 21 days. The UV-visible absorption spectra demonstrate that Zinc oxide Nanoparticles were measured in wavelengths within 200 to 300 nm. SEM image shows that the Zinc oxide nanoparticles were observed at the wavelength range from 8.40 mm. EDAX spectrum recorded two peaks located between t 0.2KeV and 8.6 KeV. XRD image shows that the diffraction peaks of Zinc oxide nanoparticles are indexed as 041;142; 123; 281; 163; and 100;200. FT-IR spectrum was observed at the wavelength range from 3512 - 1500 cm-1. The condition factor of Zebrafish was decreased in the final when compared to the initial. The feed consumption and feed conversion efficiency of Zebrafish were higher in feed V. The feed conversion ratio of Zebrafish was best in feed III. Growth and the percentage growth of Zebrafish were higher in feed VI. Assimilation and metabolism of Zebrafish were higher in feed V. Gross and Net growth efficiency were higher in feed III. All the haematological parameters increased with increased quantities of zinc oxide nanoparticles.
