Nano-Fe as feed additive improves the hematological and immunological parameters of fish, Labeo rohita H.

Abstract

An experiment was conducted to compare the effects of iron oxide nanoparticles (T 1 ) and ferrous sulfate (T 2 ) on Indian major carp, Labeo rohita H. There were significant differences (P \ 0.05) in the final weight of T 1 and T 2 compared with the control. Survival rates were not affected by the dietary treatments. Fish fed a basal diet (control) showed lower (P \ 0.05) iron content in muscle compared to T 1 and T 2 . Furthermore, the highest value (P \ 0.05) of iron content was observed in T 1 . In addition, RBCs and hemoglobin levels were significantly higher in T 1 as compared to other treated groups. Different innate immune parameters such as respiratory burst activity, bactericidal activity and myeloperoxidase activity were higher in nano-Fe-treated diet (T 1 ) as compared to other iron source (T 2 ) and control in 30 days post-feeding. Moreover, nano-Fe appeared to be more effective (P \ 0.05) than ferrous sulfate in increasing muscle iron and hemoglobin contents. Dietary administration of nanoFe did not cause any oxidative damage, but improved antioxidant enzymatic activities (SOD and GSH level) irrespective of different iron sources in the basal diet.

A comparative study of Nano-iron and zinc as feed additive on growth performance, feed efficiency and chemical body composition of Nile tilapia fingerlings (Oreochromis nilotiucs)

“…This may be attributed to the ease with which Fe nano be taken up by body and higher absorption and avilability on the contrary conventional Fe as mentation by Feng et al, (2009). Also this was agree with Behera et al (2014) who cleared that, nano-Fe appeared to be more effective than ferrous sulfate in increasing muscle iron and hemoglobin content. On the other hand, fish fed bulk Fe and Zn, their livers and gills contained Fe concentrates more than those fed Fe and Zn in nanoparticles.…”

Influence of nanoparticle-based nano-nutrients on the growth performance and physiological parameters in tilapia (Oreochromis niloticus)

“…7 Moreover, Behera et al have recently demonstrated that FeNPs supplemented in the basal diet could improve the nal weight of treated sh. 6 In another study, Muralisankar and his co-workers observed improved performance in the survival, growth and activities of fresh water prawn sh treated with a ZnNP supplementary diet. 4…”

“…Nanotechnology has been growing explosively worldwide and become a ubiquitous tool for solving various aquaculture problems, including sh nutrition, 6 water quality management, and disease treatment. During the past few years, various engineered nanoparticles [NPs] have been reported for micronutrient delivery, such as FeNPs, 6 ZnNPs, 4 SeNPs, [7][8][9] AgNPs, 10 MnNPs, 11 CuNPs 12 etc. Iron (Fe) is an essential micronutrient for the functioning of tissues and organs of animals, including sh.…”

Green synthesis of silver nanoparticles using fresh water green alga Pithophora oedogonia (Mont.) Wittrock and evaluation of their antibacterial activity

“…To date, metallic nanoparticles are mostly prepared from noble metals, i.e. silver (Vankar and Shukla 2012), gold (Dash et al 2014), copper, zinc and titanium (Schabes-Retchkiman et al 2006) as well from cadmium (Suresh 2014), iron (Behera et al 2013) and alginate (Asadi 2014). Among the noble metals, silver (Ag) is the metal of choice in the field of biological system, living organisms and medicine (Parashar et al 2009).…”
