Abstract

The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC's 7.97 ×103mm-3, RBC's 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

Highlights

Fish flesh contains the highest quality of protein, nutrients, and vitamins that our body needs, and worldwide animal protein consumption is 17% (Kwasek et al, 2020; Shah and Mraz, 2020)
The main objective of this study was to calculate the effect of Se nano-particles supplemented diet on growth, nutrients digestibility and hematology of L. rohita fingerlings
Fingerling growth performance was estimated by using the standard method as represented by Hussain et al (2015b)

Summary

Introduction

Fish flesh contains the highest quality of protein, nutrients, and vitamins that our body needs, and worldwide animal protein consumption is 17% (Kwasek et al, 2020; Shah and Mraz, 2020). Selenium is considered to be avital micronutrient for the regular performance of the body and its supplemented diet could play an important role to enhance the quality parameters like growth, hematology and nutrient digestibility (Handy et al, 2012). Nanoparticles have a wide range of applications that help in improving feed quality, absorption of nutrients, and utilization of minerals (Vijayakumar and Balakrishnan, 2014)
