Effects of vitamin E on growth performance and antioxidant status in juvenile grass carp Ctenopharyngodon idellus

Evaluation of dietary vitamin E supplementation on growth performance and antioxidant status in hybrid snakehead (Channa argus × Channa maculata )

“…In the current study, dietary vitamin E significantly affected the growth and feed intake of snakehead in a dose‐dependent manner. This result is in agreement with some previous studies on black sea bream (Peng et al., ), Beluga Huso huso (Amlashi, Falahatkar, Sattari, & Gilani, ) and grass carp (Li et al., ). Vitamin E requirements for commonly cultured fish species have been demonstrated to be ranging from 25 to 200 mg kg −1 α‐tocopherol (NRC ).…”

“…Vitamin E deficiency may give rise to muscular dystrophy, oedema of heart and muscle, anaemia and impaired erythropoiesis, depigmentation, ceroid pigment in the liver (NRC ) and even death. On the other hand, excess doses of α‐tocopherol might also exerted a pro‐oxidant effect on lipid tissues, and this has been demonstrated in rainbow trout Oncorhynchus mykis s (Tokuda & Takeuchi, ), Channa punctatus (Abdel‐Hameid, Abidi, & Khan, ) and grass carp (Li et al., ). Diet supplementation with vitamin E decreases the levels of lipid peroxidation products and protects the integrity of tissues in farmed fish (Lewis‐McCrea & Lall, ; Peng et al., ).…”

“…Furthermore, there is no information about its role in the modulation of the antioxidant defence in snakehead, being effective in preventing some of the changes in oxidative stress markers (Guzmán‐Guillén et al. ; Li et al., ; Prieto et al., ). Therefore, the purpose of this study was to evaluate the effects of dietary vitamin E on growth performance, body composition, antioxidant capacity and serum biochemistry parameter in juvenile snakehead.…”

“…And this might be associated with the antioxidant function of FA which stabilizes biological membranes and avoids cell damage (Mancuso & Santangelo, ). It was reported that ALP was involved in immune defence mechanisms and was correlated with the immune competence (Li et al., ). In studies on rats, the increase in ALP clearly exhibited that FA possessed promising hepato‐protective potential (Krishnan, Prasanna, Sabina, & Rasool, ; Panneerselvam, Subbiah, Arumugam, & Senapathy, ).…”

Optimal dietary protein level improved growth, disease resistance, intestinal immune and physical barrier function of young grass carp (Ctenopharyngodon idella)

“…The manganese superoxide dismutase (MnSOD) activity was calculated by deducting CuZnSOD from total SOD. The catalase (CAT), glutathione peroxidase (GPx) activities were assayed as described by Li et al [54]. The glutathione-S-transferases (GST) and glutathione reductase (GR) activities were measured according to Matozzo et al [55] and Chen et al [4], respectively.…”
