Effects of different dietary selenium sources (sodium selenite, selenomethionine and nanoselenium) on growth performance, muscle composition, blood enzymes and antioxidant status of common carp (Cyprinus carpio)

Abstract

This experiment was conducted to compare the effects of different sources of selenium (Se) on growth, muscle Se concentration, muscle proximate composition, blood enzymes and antioxidant status of common carp, Cyprinus carpio. Organic Se (selenomethionine, SeMet), inorganic Se (sodium selenite, Na2SeO3), or nanoselenium were each added to the basal diet at 0.7 mg Se kg−1 diet. Four groups of fish with an average weight of 9.69 ± 0.12 g were fed one of the experimental diets for 8 weeks. Nano‐Se diet resulted in better growth performance (P < 0.05). Fish fed with Se‐supplemented diets showed a higher (P < 0.05) Se content in the muscle and liver tissues. Fish fed nano‐Se had the highest liver glutathione peroxidase, superoxide dismutase and catalase activities (P < 0.05). Liver malondialdehyde level was significantly (P < 0.05) lower in fish fed on SeMet and nano‐Se diets as compared to control. The carp fed on nano‐Se diet had the lowest values of aspartate transaminase and alanine transaminase. Lactate dehydrogenase activity was significantly lower in fish fed on SeMet and nano‐Se diets. This study shows that nano‐Se acts more efficiently on growth performance and antioxidant defence system of common carp than organic and inorganic sources of Se.

“…Se as an essential nutrient for fish has been researched in many fish species, including grass carp (Liu et al, , ; Saffari, Keyvanshokooh, Zakeri, Johari, & Pasha‐Zanoosi, ; Xia et al, ; Zhou, Wang, Gu, & Li, ). Se nanoparticle (Nano‐Se) is the novel Se form and has attracted remarkable attention, as it exhibits higher bioavailability, lower toxicity and strong bioactivity in comparison with inorganic and organic Se (Saffari et al, , ; Zhou et al, ). Zhou et al () showed that Nano‐Se are more efficient in increasing muscle Se content compared to organic Se (selenomethionine, SeMet) in the crucian carp (Zhou et al, ).…”

“…However, hepatopancreatic MDA content did not decrease at Se level of 0.57 mg/kg, while which owns the highest hepatopancreatic and serum GPx activity. In previous studies, MDA was negatively correlated with increasing GPx activity in common carp and gibel carp with Se supplement (Liu et al, ; Saffari, Keyvanshokooh, Zakeri, Johari, & Pasha‐Zanoosi, ). The increased hepatopancreatic SOD at dietary Se levels of 0.79 and 1.00 mg/kg may compensate for the lack of greater expression of GPx in this study, as SOD was reported to combat oxidative stress in conjunction with GPx in the antioxidant systems (Zee, Patterson, Wiseman, & Hecker, ).…”
