The effects of dietary supplementation with mannanoligosaccharide, fructooligosaccharide or galactooligosaccharide on the growth and feed utilization of Atlantic salmon (Salmo salar)

Growth Performance, Lipid Deposition and Hepatic Lipid Metabolism Related Gene Expression in Schizothorax prenanti fed with Dietary Acidolysis-Oxidized Konjac Glucomannan Supplementation

“…The improved growth observed in the present study was similar to that reported in rainbow trout [16], common carp [17], sea bream [18]. However, the growth-promoting effect of dietary prebiotics supplementation was not observed in Atlantic salmon [19] and red drum [20]. The body composition of S. Prenanti was affected by the A-OKGM diets, the crude lipid content in fish fed with both 0.4% and 1.6% A-OKGM diets was significantly higher than that in control group.…”

Effects of Dietary Supplementation with Immunogen^® on Growth, Hematology and Gut Microbiota of Fingerling Common Carp Cyprinus carpio

“…Our fish body proximate analyses showed that the administration of prebiotic Immunogen ® did not affect the composition of the tissues (Table 3), which was not the case for Atlantic salmon Salmo salar (Grisdale-Helland et al, 2008) or rainbow trout Oncorhynchus mykis (Dimitroglou et al, 2009) fed diets containing 10 and 20 g kg -1 mannan oligosaccharide, respectively. The disparity between our results and those of other studies may relate to species, prebiotic dosages, fermentability of the prebiotics and the different intestinal morphology and microbiota of the respective fish guts (Hoseinifar et al, 2010).…”

“…Since the early years of the present century, prebiotics have been extensively tested for potentially beneficial effects on fish health, growth and survival (Mussatto and Mancilha, 2007;Grisdale-Helland et al, 2008;Yousefian and Amiri, 2009;Ebrahimi et al, 2012;Amirkolaie et al, 2013). This research has demonstrated that elevating the levels of these non-digestible dietary ingredients can have wide-ranging beneficial effects on the growth and survival of the host fish via alterations in the bacterial composition of the gut flora (Gibson and Roberfroid, 1995;Mei et al, 2011).…”

Effect of Dietary Prebiotic Mannan Oligosaccharide (MOS) on Growth Performance, Intestinal Microflora, Body Composition, Haematological and Blood Serum Biochemical Parameters of Rainbow Trout (Oncorhynchus mykiss) Juveniles

“…The better growth performance in 1.0 g MOS kgG 1 supplemented diets may be due to the production of extracellular enzymes by the gut microflora (Andrews et al, 2009). Several studies have reported improved growth performance and feed utilization of fish fed dietary mannan oligosaccharide (Torrecillas et al, 2007;Staykov et al, 2007;Yilmaz et al, 2007;Grisdale-Helland et al, 2008;Samrongpan et al, 2008;Gultepe et al, 2011;Ye et al, 2011). Mannan oligosaccharide promotes the growth of beneficial lactic acid bacteria in the intestine and these bacteria help in inhibiting the growth of pathogens by producing bacteriocins (Andrews et al, 2009).…”

“…Mannan oligosaccharide (MOS) has been shown to improve the overall condition of alimentary canal by restricting the accumulation of agents of disease and strengthening the body immune system (Staykov et al, 2007). Several studies have demonstrated that prebiotic of mannan oligosaccharide (MOS) can improve the growth parameters, survival, hematological and biochemical parameters, gut morphology and modulate the intestinal microbiota in various aquatic species, including sea bass (Dicentrarchus labrax) (Torrecillas et al, 2007), rainbow trout (Oncorhynchus mykiss) (Staykov et al, 2007;Yilmaz et al, 2007;Dimitroglou et al, 2009), atlantic salmon (Salmo salar) (Grisdale-Helland et al, 2008); Nile tilapia (Oreochromis niloticus) (Samrongpan et al, 2008), rohu (Labeo rohita) (Andrews et al, 2009), sea bream (Sparus aurata) (Gultepe et al, 2011), japanese flounder (Paralichthys olivaceus) (Ye et al, 2011). Rainbow trout (Oncorhynchus mykiss) is one of the most commercially important species grown in Iran and all around the world.…”
