Effects of dietary xylooligosaccharide on growth and feeding performance, body composition and physiological responses of sobaity seabream ( Sparidentex hasta ) juvenile

Abstract

The aim of this study was to evaluate the effects of xylooligosaccharide (XOS) on growth performance, haemato‐immunological responses, body composition and digestive enzymes activity of sobaity seabream juvenile (Sparidentex hasta) with an average weight of 35.64 ± 0.30 g. Fish were fed with experimental diet containing 0, 5 and 10 g XOS kg−1 for 8 weeks. The obtained results indicated that dietary XOS did not change sobaity seabream growth, feed utilization and body composition (p > 0.05). The results of this study indicated that different levels of prebiotic did not affect haemato‐immunological parameters except for complement activity (p < 0.05). Digestive enzymes including lipase and amylase activity did not affected by XOS treatment but protease activity decreased significantly in fish fed 0.5% XOS compared to the control group (p < 0.05). Overall, results revealed that adding 0.5% XOS could be beneficial as an immunostimulant for general health status as well as an immune and stress resistance promoter. There were no significant effects through dietary XOS on other parameters measured in this study. Therefore, it is concluded that the levels of dietary XOS can differ according to the aim of use.

Prebiotic effects of dietary xylooligosaccharides on fish gut microbiota, growth, and immunological parameters – A review

“…XOSs made from corn cobs using Aspergillus xylanase in Nile tilapia showed prebiotic effects (Van Doan et al, 2018. Morshedi et al (2018) used XOS from corn cobs and found no significant prebiotic effects compared to the control group. Azeredo et al (2017) discovered that XOS from corn cobs increased lysozyme activity but had no effects on total immunoglobulins, bactericidal activity, or complement content in experimental trials.…”

“…Moreover, XOSs fermentation by beneficial gut bacteria may benefit fish by providing energy from the simple soluble sugars produced and preventing the colonisation of pathogenic microbes in fish gut (Manning and Gibson, 2004;Vázquez et al, 2005). Systemic XOSs fermentation by Bifidobacterium species and LAB increases glycolysis and digestive enzyme activity (Guerreiro et al, 2016;Morshedi et al, 2018), resulting in improved growth performance and body composition of fish. However, adding XOSs to the diet of Sparidentex hasta did not affect intestinal lipase and amylase activities (Morshedi et al, 2018).…”

“…A number of prebiotics have been used in aquaculture to boost growth performance, immunological response, and disease resistance among many fish species (Grisdale-Helland et al, 2008;Burr et al, 2010;Merrifield et al, 2010 b;Hoseinifar et al, 2013). XOSs have recently attracted the attention of researchers for their potential use in aquaculture (Guerreiro et al, 2015 b;Van Doan et al, 2018Morshedi et al, 2018). XOSs are xylose-linked (-(1)4)-linkages) oligomers formed by steam, chemical, and enzymatic hydrolysis of xylan-containing lignocellulosic biomass (Aachary and Prapulla, 2011).…”

Effects of exogenous multienzyme complex supplementation in diets on growth performance, digestive enzyme activity and non‐specific immunity of the Japanese seabass,Lateolabrax japonicus

“…Current researches of scholars in different directions are looking for ways to resolve such problems, which gets a great success in the use of green feed additive. Researches show some green feed additive, such as Chinese herbal medicines (Pu, Li, Du, Cui, & Xu, 2017;Wang et al, 2018), oligosaccharides (Lee et al, 2018;Morshedi et al, 2018) and probiotics (Lee et al, 2018;Wang, Li, & Lin, 2008) that can enhance the fish growth performance, immunity, product quality and improve the aquaculture environment. As a new green feed additive, exogenous feed enzymes are primarily produced by microbial fermentation, which is a natural, environmental-friendly and safe process (Ravindran & Son, 2011).…”

Effect of dietary prebiotic fructooligosaccharide on histology, digestive enzyme activity, biochemical and immunological parameters of Asian seabass (Lates calcarifer) juveniles

“…FOS are not significantly digested in small intestine but fermented in the large intestine to selectively stimulate growth performance and survival of some health promoting bacteria such as lactobacilli and bifidobacteiral species (Wu et al, 2013). Supplementation of dietary prebiotics has been shown to improve the health and growth performance of various aquatic species (Safari et al, 2014;Eshaghzadeh et al, 2015;Guerreiro et al, 2015;Ali et al, 2016Ali et al, , 2017aAli et al, , b, c, 2018Morshedi et al, 2018). Therefore the current study was carried out to investigate the effect of dietary fructooligosaccharide supplementation on intestinal and liver histology, digestive enzyme activity, biochemical and immunological parameters of L. calcarifer fingerlings.…”
