Effects of dietary propolis and vitamin E on growth performance and antioxidant status in blood of juvenile Rainbow trout, Oncorhynchus mykiss (Teleostei: Salmoniformes) under different flow rates

Abstract: The present study investigated the effects of propolis and vitamin E supplementation in diets of juvenil rainbow trout subjected to two different flow rates with or without flow stress (0.9 and 2.1 l/min, respectively) on final weigth (FW), condition factor (CF), feed conservation ratio (FCR), protein efficiency ratio (PER) and vitamin A, C and E concentrations and malondialdehyde (MDA) levels in serum as well as plasma superoxide dismutase (SOD) activity. The experimental groups were as follows: group C was f… Show more

“…Dietary supplementation of VE improved the feed efficiency of soft–shell turtle, Pelodiscus sinensis ( Huang and Lin, 2004 ), which is consistent with our results. Several studies revealed that VE supplementation through diet improved the production and feed efficiency of parrot fish Oplegnathus fasciatus ( Galaz et al, 2010 ), Rainbow trout Oncorhynchus mykiss ( Kelestemur et al, 2012 ), zebrafish Danio rerio ( Mehrad et al, 2012 ), yellow catfish Pelteobagrus fulvidraco ( Lu et al, 2016 ), turbot Scophthalmus maximus ( Niu et al, 2014 ), channel catfish Ictalurus punctatus ( He et al, 2017 ) and largemouth bass Micropterus salmoides ( Li et al, 2018 ). The growth improvement could be a reflection of better utilization of essential nutrients, which may be attributed to enhance intestinal height and mucosal thickness ( He et al, 2017 ), stimulate the digestive and absorptive capability of host fish ( Farhangi and Carter, 2001 ).…”

“…Overall, studies concerning the antioxidant effects of vitamin E of commercial-sized European sea bass are rare. Silva et al [114] recommended a dosage of 500 mg kg −1 of vitamin E for adult sea bass. However, data obtained in this study suggests that a 500 mg kg −1 inclusion of vitamin E (VITE diet) in European sea bass feeds have no beneficial effect on muscle antioxidant potential compared to the traditional dosage of 100 mg kg −1 (CTRL diet).…”

“…For instance, dietary propolis extracts (aqueous or ethanolic) increased serum lysozyme and immune cells production and activity of tilapia species such as Mozambique tilapia Oreochromis mossambicus [19] and Nile tilapia [15,35] as well as for rainbow trout [22,36,37], common carp [23] and Japanese eel [24]. In addition, propolis also mitigated toxic effects and oxidative stress in fish exposed to exogenous chemical compounds or environmental stress [20,25,[38][39][40].…”
