Effects of dietary vitamin E on growth performance, antioxidant capacity and lipid metabolism of juvenile golden pompano Trachinotus ovatus

Abstract

Vitamin E (VE), consisting of tocopherols, tocotrienols and the derivatives, serves as a lipid-soluble antioxidant providing nutrients to animals including fish (Bramley et al., 2000). Its primary function is to act as a free radical scavenger that protects cells and tissues against the deleterious effects of free radicals (Liu et al., 2018;Naderi et al., 2019;Wang et al., 2019). Besides, VE can increase antioxidant ability of fish by enhancing the antioxidant enzyme activities containing superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), such as largemouth bass (Micropterus salmoides) (Li et al., 2018), hybrid snakehead (Channa argus × Channa maculata)

Vitamin E Ameliorates Impaired Ovarian Development, Oxidative Stress, and Disrupted Lipid Metabolism in Oreochromis niloticus Fed with a Diet Containing Olive Oil Instead of Fish Oil

“…golden pompano [37], and blunt bream (Megalobrama ambycephala) [38], appropriate VE supplementation was found to have a growth-promoting effect, although high doses of VE did not further increase fish growth. Previous studies have shown that 50-100 mg/kg VE can meet the growth demands for Nile tilapia at a dietary lipid level of 50 g/kg [18].…”

“…In the present study, the dietary VE level did not significantly affect the growth performance of female tilapia. In studies on spotted seabass ( Lateolabrax macroatus ) [ 36 ], golden pompano [ 37 ], and blunt snout bream ( Megalobrama ambycephala ) [ 38 ], appropriate VE supplementation was found to have a growth-promoting effect, although high doses of VE did not further increase fish growth. Previous studies have shown that 50–100 mg/kg VE can meet the growth demands for Nile tilapia at a dietary lipid level of 50 g/kg [ 18 ].…”

“…Gonad development in fish is mainly influenced by environmental conditions and feed nutrition. Research has shown that high-quality protein and lipid sources, as well as appropriate vitamin levels, can improve reproductive performance and accelerate oocyte development in fish [ 37 , 39 ]. Studies on tongue sole [ 8 ], Atlantic Salmon [ 9 ], and sterlet sturgeon [ 10 ] have shown that partially replacing FO with OA-enriched OO or RO can improve the egg quality and reproductive performance of broodstock.…”

Potential of Insect Life Stages as Functional Ingredients for Improved Nutrition and Health

“…Moreover, vitamins contribute to the development of the immune system, while also helping in the digestion of other nutrients [ 81 , 82 ]. The fat-soluble vitamins (α and γ tocopherols) are good natural antioxidants that impede lipid oxidation in biological systems by stabilizing hydroperoxyl and in mopping out other free radicals [ 83 , 84 , 85 ]. As vitamins cannot be synthesized de novo by animals, they must be supplied constantly by food, thus incorporation of the studied insects in diets would likely serve as an alternative source of vitamins.…”

Effects of Organophosphate and Pyrethroid Insecticides Mixture on the Haemato-Biochemical and Histological Function of Male Albino Rats

“…Organophosphate (OP) compounds are most commonly used insecticides which non-competitively inhibit the enzymatic activity of acetylcholine esterase which metabolizes acetylcholine. The enhanced cholinergic activity of muscarinic and nicotinic acetylcholine receptors causes the acute symptoms of OP poisoning (Zhang et al, 2021;Yongcai et al, 2020 andMinton andMurray, 1988). Pyrethroids are ion channel poisons that prolong neuronal excitement without being cytotoxic.…”
