“…Depending upon the fish species and the study, it has been shown that dietary administration of b-glucan enhances or does not alter lysozyme or complement activities (Kiron 2012). For other kinds of supplementation the lysozyme or complement activities are also variable in Siberian sturgeon (Eslamloo et al 2012;Geraylou et al 2012Geraylou et al , 2013Kolman 2001;Xie et al 2006). In our study, both lysozyme and complement activities are unmodified by dietary supplementation.…”

“…Studies on the bacterial community in the sturgeon hindgut using PCR-DGGE have revealed that AXOS mainly stimulated the growth of lactic acid bacteria and Clostridium sp., with AXOS-32-0.30 having more pronounced effects. Thus, AXOS improved sturgeon health through prebiotic action (Geraylou et al 2012). Thus, 8000 mg/kg OKGM is beneficial to the growth of S. prenanti (Zhang et al 2013), which may have been caused by the gut microbiota.…”

Prenant's schizothoracin (Schizothorax prenanti) is an important existemic commercial fish in Yangtze River. Oxidized konjac glucomannan (OKGM) is a kind of polysaccharide oxidative degraded from konjac glucomannan. The diet of S. prenanti was supplemented with 500, 1000, 2000, 4000, and 8000 mg/kg OKGM. After a 60-day feeding trial, Escherichia coli, Salmonella, Lactobacillus, and Bifidobacterium in the intestines of S. prenanti were quantified, and intestinal flora was analyzed using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). Intestinal plica mucosa height, mucosa epithelial height, submucosa thickness, inner circular muscularis thickness, and outer longitudinal muscularis thickness were measured. In the foregut and midgut, Lactobacillus in the 2000, 4000, and 8000 mg/kg dose groups were significantly (P \ 0.05) higher than that of the control group. In the hindgut, E. coli and Salmonella of the 4000 and 8000 mg/kg dose groups were significantly (P \ 0.05) lower than those of the control group, but Lactobacillus and Bifidobacterium in these groups were significantly (P \ 0.05) more than those of the control group. The bands from PCR-DGGE of the control and 500 mg/kg dose groups were found to be highly similar, as well as the 4000 and 8000 mg/kg dose groups. The intestinal length index of the 8000 mg/kg dose group was significantly (P \ 0.05) lower than that of the control group. The plica mucosa height in the gut of the 8000 mg/kg dose group was significantly (P \ 0.05) higher than that of the control group. The mucosa epithelial height and inner circular muscularis thickness in the midgut and hindgut of the 8000 mg/kg dose group were significantly (P \ 0.05) higher than those of the control group. Hence, OKGM is beneficial to gut health. OKGM doses of 4000 and 8000 mg/kg in the diet significantly affected the intestinal morphology and intestinal microflora of S. prenanti, and the optimal dose was 8000 mg/kg.

“…In addition, there are a lot of other factors that may influence the success of prebiotic supplements. As a typical example, it has been clearly shown for arabinoxylans from wheat and other cereals that differences in pretreatment may determine the expected effect in different animal species and in humans , to the point that different degrees of polymerisation and substitution of arabinoxylanoligosaccharides may exert different effects (Damen et al, 2011;Geraylou et al, 2012). These compounds do induce a shift in the microbiota composition and can suppress Salmonella colonisation (Eeckhaut et al, 2008).…”

Dysbiosis or dysbacteriosis is defined as a shift in the intestinal microbiota composition resulting in an imbalance between beneficial and harmful bacteria. Since the ban on the use of growth-promoting antibiotics in animal feed in the EU, dysbiosis has emerged as a major problem in intensive animal production. Prebiotics and probiotics are currently under investigation as possible alternatives to growth-promoting antibiotics, as their mode of action is thought to be based largely on a modulation of the composition and function of the intestinal microbiota. In this review, we analyse the currently available data from both animal and human nutrition that document the potential and limitations of prebiotics and probiotics for the control of dysbiosis. An impressive number of empirical feeding trials have been carried out in healthy animals, yielding sometimes contradictory results. More indepth studies have revealed the complexity of the interactions taking place in the lower intestinal tract, thus illustrating that preand probiotics cannot be a simple replacement for growth-promoting antibiotics. Although there are indications that the strategic use of pre-and probiotics can provide major benefits, there is still a lack of basic knowledge on the delicate interactions between the microbiota, the host and the feed components, which hampers the widespread use of these valuable feed additives.
